Top 10 MFP community falsehoods

I get really tired of reading all of the broscience and bad information passed around here as if it's going to help someone. I thought I'd compile a list of things that irritate me the most. Feel free to add your own. I'm writing this post because IMHO this community *should* be a place for people to come and get support, advice, and techniques that will help them with their fitness goals. I hope that in some small way I can help push the group back in that direction and away from the "I know better than everyone, listen to me!!!" theme that we currently seem to have. And yes, I do recognize the irony in that statement, as I'm about to list out a bunch of things that I know to be correct in spite of the trends. I'll add that I didn't come up with this stuff on my own. Much smarter people than me have done the real work, the real research, and published their real findings. I'm just summarizing their efforts in my own words. I hope someone finds it helpful.
Before I start the list, a personal disclaimer: I'm not a doctor. I'm not a nutritionist. I'm a fat, nerdy engineer. I'm less fat than I used to be (down a total of almost 70 lbs from a year ago, 34 since joining MFP about 10 weeks ago) but I'm still working on my own weight loss journey. That said, my job... nay, my very nature is to gather as much credible information as I can and sort the wheat (OMG GLUTEN!) from the chaff, as it were. I am very good at troubleshooting and problem solving. Historically I'm not very good with discipline, but that's something I'm working on. I recognize that as a personal weakness. I'm willing to bet that it's something almost all of us are working on. That segues nicely into the first item on the list:
1.) Something else is to blame, not me!
This is the biggest problem in the fitness community, so I've kinda grouped lots of falsehoods into this one item. Many reputable studies have found that the one thing lacking from every unsuccessful diet plan is discipline. Whatever goals you choose to set for yourself, you have to stick with a plan that gets you to those goals. The falsehoods surrounding discipline are too many to list entirely, but pretty much everything from "I did that and then gained back all the weight" to "that won't work because it didn't work for me" all boil down to a lack of discipline. Of *course* you gained weight after you stopped adhering to your diet plan... i mean... duh, amirite? You can't eat nothing but chicken and veggies for a year then go back to pigging out at Pizza Hut every day and feign surprise at your resulting spare tire. You definitely can't blame it on the chicken and veggies. A *lot* of people do, though. The diet gets blamed for what happened after you stopped the diet... that's crazy, IMO. Before you start looking for a place to point a finger, ask yourself honestly: "am I really being as disciplined as I should be?" Less discipline (and/or falling prey to broscience) will result in slower results. For some people that slower pace is fine, but it's not necessary or even more "healthy". If you are obese or overweight, you can lose weight quickly. It only needs to slow down as you get closer to your goal. Plateaus are not "just a part of weight loss", they are usually either a failure in diet and exercise plan adherence or failure to properly adjust one's diet and exercise plan. Blaming that plateau on something else, or even accepting it as normal, will only slow your progress.
2.) This must be right because it feels right, or it's easier
I almost made this #1 because it really results in a lot more false information than anything else. People seem to think that there is some kind of magic behind weight loss. As if there is one plan out there that is better than the rest, and only the people on that plan will ever have real or lasting results. Sounds a lot like religion for a reason... basic human nature is to make oneself comfortable. We have a goal, but we justify not meeting it or adjusting it because we want to make ourselves more comfortable. "Eat more to lose" is the best example I know of. Yes, you can eat more and still lose weight. Of course you can. That's a fantastic plan for a lot of people, psychologically. It makes us more comfortable and even though it slows down progress it does get results. The problem with it is that 2-3 times per day I read a response from someone that "you need to eat more to lose weight". That's 100% incorrect. Science has proven this 10 ways in every direction, but people still believe it because it makes them feel good about the amount they are currently eating. Convincing oneself that it's necessary is a great way to avoid guilt. The same goes for people who swear that even for obese people, a specific number of lbs per week is the maximum "healthy" rate of loss. There is no science to support that exact number. There *is* science to support the limit of roughly 6% of your body's fat mass per week as an upper limit on the rate of fat loss.
Another good example is the "your problem is that you are addicted to the scale" argument. Preposterous. There is nothing wrong with weighing yourself every 5 minutes if you want to. All data is good data. I personally don't have time to weigh every 5 minutes but if I were a scientist conducting a weight loss experiment, I would be pretty pissed off if the guy assigned to taking measurements decided that once every 7 days was enough because he didn't understand or like what the daily values said. In essence, we are all scientists in this experiment. No, the number on the scale isn't going to give you warm fuzzies every time you step on it... but knowing what you weigh each and every day has real value. Being able to trend and adjust accordingly will get you faster results. Psychology strikes again... people don't like the way something *feels* so they tell everyone that it's bad to do that thing. And other people *believe* it. People use words like "healthy" and "recommended" to bolster the credibility of the thing they're pushing.
The only real truth behind these things lies in the psychological benefits. People who exercise their willpower as much as their bodies will have faster success and keep it off. And they'll do it in a perfectly healthy way.
3.) Heavy Lifting makes women bulky
Nope. For men, eating at a surplus, heavy lifting can result in a decent rate of muscle growth. 20 lbs per year on a large-framed and very dedicated man is possible, but not very common. For women (who have a normal hormonal balance) it takes even longer than that. An average woman with an average frame (let's say 5'4") could potentially gain 5-10 lbs of muscle in a full year of dedicated heavy lifting. it's usually on the lower end of that scale, and 5 lbs of muscle spread out over the entire body is not incredibly obvious. Certainly not to the point of being considered bulky. What heavy lifting *does* accomplish, for both sexes, is a solid caloric burn that is not nearly as affected by muscle efficiency. As we lose body weight, cardio exercises like walking and running become less effective for two primary reasons. The first is that our workload (body weight) is decreasing, so it takes fewer calories to accomplish the same level of effort. The second is that our muscles become much better at performing those tasks. Cardio exercises work the same muscle groups every time, at the same (usually even decreasing) levels of effort. Heavy lifting helps counter the effects of muscle efficiency by not relying on pure body weight for workload. Increasing your workload regularly, instead of decreasing it, means constantly challenging your muscles to do more work than they're used to. This plan works well for women and for men. HIIT can have similar effects, but still relies on body weight for workload.
4.) Muscle gain is not possible on a deficit, and LBM loss always happens with fat loss
Not really. Muscle gain on a daily deficit is slower, that much is true. It is a lot slower in most cases. But it's not impossible, nor is LBM loss a requirement for fat loss. People preach these two ideas every single day on these forums, but science does not support them. For starters, the concept of a daily deficit is inherently flawed. You body is constantly (as in, all day every day) going through peaks and valleys of available nutrients. In the peaks it will use as much of these nutrients as it needs and either "flush" or store the rest. There are natural rate limiters on how fast you can digest and absorb nutrients into the bloodstream, and how fast you can use and store them. Anything that cannot be absorbed and used or stored before it is eliminated… well, gets flushed. As a whole, these limits are commonly referred to as your "metabolism" (which I will get into on the next point). when your body needs to do things like "perform this exercise" or "repair this muscle" it will find a way to do that. If there are carbs and fats available in the bloodstream, they get used. If there are not, fat stores are used. If fat isn't available, or if your fat is currently at maximum energy-providing capacity, proteins are used. If you don't have proteins available from dietary sources, LBM is used.
The body finds a way, but it only hurts itself if necessary to survive. Not all LBM loss is damaging, but the body prefers to avoid that scenario as long as it can. Assuming you have the right mix of nutrients available for muscle repair when muscles need to be repaired, they will be. It doesn't matter that you were in a valley earlier today if you're in a peak right now. Granted, muscle repair and building are a long process that usually takes a day or two post-workout... so being at an overall daily deficit (more valleys than peaks during the day, etc) will generally not result in much hypertrophy (muscles getting bigger than they were before) because there just isn't spare stuff to go around. Some will still happen though, assuming you are lifting heavy and eating lots of protein. More importantly, a high protein diet coupled with a heavy lifting routine will help *spare* the LBM you already have. That should be the primary goal of anyone (like me) who started this thing fat and wants to end up with a muscular physique. Hypertrophy happens when there are nutrients available during the repair phase. They are converted and stored in muscle rather than fat more readily during this process. That said, if you are at a caloric deficit for the majority of time you are in muscle repair, your body just won't have enough to increase your muscle stores. Gaining muscle on a daily deficit is difficult, but again - possible.
5.) I have a slow Metabolism
Your metabolism is not by default faster or slower than everyone else's. It just isn't. Your level of physical activity, your diet, your current state of and/or history of obesity, and your overall size and frame do affect your metabolism. But yours is going to be pretty much the same as someone else with the same background and stats. As with all things, there is some variation within those groups, but it's not a significant amount. Your Metabolism, as we commonly call it, is actually a measure of the rate at which your body can digest, absorb, and put nutrients to use. This rate is primarily governed by the health of your organs and the levels of several different hormones in your bloodstream. There *are* people with naturally higher levels of these hormones, or natural resistance to them... but it's not nearly common enough for so many weight problems to be blamed on genetics or "slow metabolisms". But, we still like to blame things (see point #2), so we do. Also, eating 9x per day will not keep your metabolism in high gear. Nor will eating certain foods like raspberry ketones. Your metabolism just doesn't have multiple speeds that you can control in such ways.
6.) Gluten
Yes, a very (very) small percentage of the population has Celiac disease. Another very small percentage has a general intolerance to gluten. But, you almost certainly are not one of them. It seems like an easy out (see point #2... again) and this is currently a very popular place to point the blame cannon... but chances are going Gluten free will not help you lose anything other than money. For those who truly are affected, there are no ifs, ands, or buts about it. Trying gluten-free as a "lifestyle choice" when it isn't necessary is bordering on insane (by Einstein's poignant definition of the word), regardless of if you have convinced yourself that it has had some positive effect. If you really think you might need to go gluten-free, go see your doctor first. There are ways to know for sure if it's a necessary sacrifice or if you're just falling prey to the latest craze. Either way, a real intolerance to gluten does not generally result in weight gain.
7.) Starvation mode
No. Just... No. Most people here know by now that starvation mode is complete BS, but I had to include it. Your body will not "hold onto fat" because you are eating too few calories, that's silly. And impossible. Stop it. Seriously.
8.) Trainers know best
This one is touchy because there really are some good trainers out there. But, it does not take a medical (or any other type of) genius to become a trainer. There are certifications to be had, but most of them don't really prove anything either. Again, some people really are good at it, but as with any scientific profession that doesn't require scientific proficiency... there are plenty of bad ones out there making money off of the unsuspecting public. Being a bad trainer for a long time does not make one a good trainer. Having a good build and a fancy logo on one's under armor shirt doesn't either. Be careful when you select a trainer. Just because what they're doing works, doesn't mean it's the best or the only way to accomplish your goal. A perfect example is a friend of mine who is paying a trainer over $400 per month to give him bad advice. I won't go into details of how bad that advice is... but he is guilty of pretty much every item on this list. And he's getting paid well for it. Again, be careful. Be selective. Do your own research first... you probably don't need a trainer. If you do decide to hire one, arm yourself with enough knowledge to be able to tell on your own whether or not he's full of sh… er, broscience.
9.) TDEE / BMR
This one is a big problem, and really should be higher on the list... but I guess they're all big problems. Relying on TDEE and BMR calculators is bonkers. They're estimates, and some of the methods can be pretty accurate for some people. That said, *most* people use them incorrectly. There are so many factors that determine what your actual daily nutritional needs are, that no online calculator can ever give you a perfect answer. The first mistake people make is under or overestimating the normal level of activity they have in a day (and/or counting normal activity twice by adding it to TDEE). The second is believing that the resulting number (or even an average of several methods' numbers) is truly accurate. It isn't. It can't be. It can be close at times, and I'm sure that just like with the lottery sometimes the number is actually hit on the head... but that's pure luck. The chances of you being one of the few people who gets that right number are so slim that you might as well just not use the calculator. If you do still want to use it, understand that it is a *tool* just like all the other tools we have at our disposal. It may well get you in the general vicinity of where you need to be, but it's an exercise in futility to attempt precision in the measurement and execution of a diet plan when you are basing it on an inherently imprecise number. TDEE and BMR are both touted as some magic numbers that must have some specific method applied to them. BMR is *not* the minimum number of calories you need to eat to survive. TDEE - 20% is *not* the only, the best, or the fastest way to lose fat. It's not even a really good way. It doesn't line up with science in any but the most average of scenarios. Since almost none of us will start or finish our weight loss journey as an average person… why use something that is designed for the average person? Figure out how much your fat mass weighs. Calculate 31kcal per day per lb of fat mass. That's your maximum sustainable deficit, without cutting into LBM too often. Find a point somewhere between maintenance and that number that gets you to your goal as fast or as slow as you want to get there.
10.) I did something and got results, so that is the way.
This might as well be #1... I give up on prioritizing these things. Regardless of its place on my list this is very important. Things get repeated as gospel because they "worked" for someone. 9 times out of 10 the "results" of a fad diet or some random broscience are just a side effect. Correlation does not equal causation. If every dieter on this board were to start rubbing their heads while patting their bellies every day as they walked for 3 miles, I can pretty much guarantee that the success would get attributed to the rubbing and the patting, not the walking. Similarly, every fad diet is 10% solid advice dressed up with 90% new/special/ultimate crap. People start paying a lot more attention to the number of calories they take in because they now have the new, perfect, secret plan... when really all they needed to do was just pay attention to the calories. But, they did the crazy thing and they got results... so the crazy thing gets the glory.
footnote - Adaptive Thermogenesis
AT itself is not a falsehood. I already have 10 of those on my list, but AT deserves a mention on this list because it *is* a real thing that gets manipulated and otherwise falsified quite often. People will see the effects of AT and call it something else. Or, they will think that they have done irreparable damage to their bodies because of the effects of AT. Adaptive Thermogenesis is, when simplified, a reduction in overall body temperature. The body generates heat while metabolizing food (and doing lots of other things), keeping it at a regular 98.6F for the average person as often as possible. Evolution has produced that magic number because that's where our bodies are generally the most efficient. Adaptive Thermogenesis is a process by which the body recognizes a need to survive on a consistently lower intake of food and thus concedes some efficiency in the name of overall survival. It does not happen immediately and it is not permanent. Hormone levels change slightly to alter the rate at which food is metabolized. There is a limit to this adjustment, though. At a certain point the body has to keep on living, so it can't slow these processes down any more. The limit on the effects of AT has been proven to be about 20%, and only in extreme cases.
Think of it like a campfire. You would like to keep that fire nice and big to cook on, to warm your feet on, and to toast those marshmallows. But, if the guy bringing you firewood isn't bringing it as fast as you'd like, you have to let that fire get a little bit smaller so you can keep it going long-term. The same analogy can be used for repairing your metabolic rate (the size of your campfire). Once you are satisfied that the firewood guy is going to supply you with enough to keep that campfire at optimum levels, you will add more wood to the fire more quickly. It doesn't take a very long time for your body to adjust its hormonal balance and regulate its temperature (and therefore metabolic rate) back up to normal. a few days to a few months, depending on how long you were at a significant deficit. One interesting exception is that of formerly obese people. AT effects can take much longer to overcome, primarily because people who are obese for a very long time have significant hormonal imbalances to repair. This is true whether they used a small or large deficit to lose their weight, however. It's not quite the same as the normal AT discussion, but it's part of the same puzzle.
references
I have far too many references to list. I originally intended to list the most useful ones, but in my mind that sort of defeats the purpose of this post. I'd much prefer that people actually do some research for themselves. Real, scientific studies are out there and available for your perusal. I don't put much stock in forum posts (more irony!) or non-scientific websites. I do enjoy authors like Lyle MacDonald and Mike Roussel, but I mainly use their writings as jumping-off points to go read the actual studies. It is vitally important to compare and contrast the results of every study you can find. The keys to success are applying the knowledge you gain to your own plan, and adjusting based on your personal results. I'm sure I have a few errors in there somewhere, but I've tried hard to lean as heavily as possible on the actual science and avoid putting my own spin on things.
TL;DR - There is no secret to fat loss. The only way to lose fat is to force your body to burn fat. The only way to do that is to consume fewer calories than you burn every day. The only way to know for sure if you're doing that is to measure your intake, your weight, and your fat mass as precisely and as often as possible. Use these measurements to verify and adjust your diet and exercise plan, and you will succeed. All the rest of the crap is just crap.
Before I start the list, a personal disclaimer: I'm not a doctor. I'm not a nutritionist. I'm a fat, nerdy engineer. I'm less fat than I used to be (down a total of almost 70 lbs from a year ago, 34 since joining MFP about 10 weeks ago) but I'm still working on my own weight loss journey.

Of *course* you gained weight after you stopped adhering to your diet plan... i mean... duh, amirite? You can't eat nothing but chicken and veggies for a year then go back to pigging out at Pizza Hut every day and feign surprise at your resulting spare tire.

Less discipline (and/or falling prey to broscience) will result in slower results. For some people that slower pace is fine, but it's not necessary or even more "healthy". If you are obese or overweight, you can lose weight quickly. It only needs to slow down as you get closer to your goal. Plateaus are not "just a part of weight loss", they are usually either a failure in diet and exercise plan adherence or failure to properly adjust one's diet and exercise plan.

For women (who have a normal hormonal balance) it takes even longer than that.

If you do decide to hire one, arm yourself with enough knowledge to be able to tell on your own whether or not he's full of sh… er, broscience.
9.) TDEE / BMR
This one is a big problem, and really should be higher on the list... but I guess they're all big problems. Relying on TDEE and BMR calculators is bonkers. They're estimates, and some of the methods can be pretty accurate for some people. That said, *most* people use them incorrectly. There are so many factors that determine what your actual daily nutritional needs are, that no online calculator can ever give you a perfect answer. The first mistake people make is under or overestimating the normal level of activity they have in a day (and/or counting normal activity twice by adding it to TDEE). The second is believing that the resulting number (or even an average of several methods' numbers) is truly accurate. It isn't. It can't be. It can be close at times, and I'm sure that just like with the lottery sometimes the number is actually hit on the head... but that's pure luck. The chances of you being one of the few people who gets that right number are so slim that you might as well just not use the calculator. If you do still want to use it, understand that it is a *tool* just like all the other tools we have at our disposal. It may well get you in the general vicinity of where you need to be, but it's an exercise in futility to attempt precision in the measurement and execution of a diet plan when you are basing it on an inherently imprecise number. TDEE and BMR are both touted as some magic numbers that must have some specific method applied to them. BMR is *not* the minimum number of calories you need to eat to survive. TDEE - 20% is *not* the only, the best, or the fastest way to lose fat. It's not even a really good way. It doesn't line up with science in any but the most average of scenarios. Since almost none of us will start or finish our weight loss journey as an average person… why use something that is designed for the average person? Figure out how much your fat mass weighs. Calculate 31kcal per day per lb of fat mass. That's your maximum sustainable deficit, without cutting into LBM too often. Find a point somewhere between maintenance and that number that gets you to your goal as fast or as slow as you want to get there.
10.) I did something and got results, so that is the way.
This might as well be #1... I give up on prioritizing these things. Regardless of its place on my list this is very important. Things get repeated as gospel because they "worked" for someone. 9 times out of 10 the "results" of a fad diet or some random broscience are just a side effect. Correlation does not equal causation. If every dieter on this board were to start rubbing their heads while patting their bellies every day as they walked for 3 miles, I can pretty much guarantee that the success would get attributed to the rubbing and the patting, not the walking. Similarly, every fad diet is 10% solid advice dressed up with 90% new/special/ultimate crap. People start paying a lot more attention to the number of calories they take in because they now have the new, perfect, secret plan... when really all they needed to do was just pay attention to the calories. But, they did the crazy thing and they got results... so the crazy thing gets the glory.
footnote - Adaptive Thermogenesis
AT itself is not a falsehood. I already have 10 of those on my list, but AT deserves a mention on this list because it *is* a real thing that gets manipulated and otherwise falsified quite often. People will see the effects of AT and call it something else. Or, they will think that they have done irreparable damage to their bodies because of the effects of AT. Adaptive Thermogenesis is, when simplified, a reduction in overall body temperature. The body generates heat while metabolizing food (and doing lots of other things), keeping it at a regular 98.6F for the average person as often as possible. Evolution has produced that magic number because that's where our bodies are generally the most efficient. Adaptive Thermogenesis is a process by which the body recognizes a need to survive on a consistently lower intake of food and thus concedes some efficiency in the name of overall survival. It does not happen immediately and it is not permanent. Hormone levels change slightly to alter the rate at which food is metabolized. There is a limit to this adjustment, though. At a certain point the body has to keep on living, so it can't slow these processes down any more. The limit on the effects of AT has been proven to be about 20%, and only in extreme cases.
Think of it like a campfire. You would like to keep that fire nice and big to cook on, to warm your feet on, and to toast those marshmallows. But, if the guy bringing you firewood isn't bringing it as fast as you'd like, you have to let that fire get a little bit smaller so you can keep it going long-term. The same analogy can be used for repairing your metabolic rate (the size of your campfire). Once you are satisfied that the firewood guy is going to supply you with enough to keep that campfire at optimum levels, you will add more wood to the fire more quickly. It doesn't take a very long time for your body to adjust its hormonal balance and regulate its temperature (and therefore metabolic rate) back up to normal. a few days to a few months, depending on how long you were at a significant deficit. One interesting exception is that of formerly obese people. AT effects can take much longer to overcome, primarily because people who are obese for a very long time have significant hormonal imbalances to repair. This is true whether they used a small or large deficit to lose their weight, however. It's not quite the same as the normal AT discussion, but it's part of the same puzzle.
references
I have far too many references to list. I originally intended to list the most useful ones, but in my mind that sort of defeats the purpose of this post. I'd much prefer that people actually do some research for themselves. Real, scientific studies are out there and available for your perusal. I don't put much stock in forum posts (more irony!) or non-scientific websites. I do enjoy authors like Lyle MacDonald and Mike Roussel, but I mainly use their writings as jumping-off points to go read the actual studies. It is vitally important to compare and contrast the results of every study you can find. The keys to success are applying the knowledge you gain to your own plan, and adjusting based on your personal results. I'm sure I have a few errors in there somewhere, but I've tried hard to lean as heavily as possible on the actual science and avoid putting my own spin on things.
TL;DR - There is no secret to fat loss. The only way to lose fat is to force your body to burn fat. The only way to do that is to consume fewer calories than you burn every day. The only way to know for sure if you're doing that is to measure your intake, your weight, and your fat mass as precisely and as often as possible. Use these measurements to verify and adjust your diet and exercise plan, and you will succeed. All the rest of the crap is just crap.

I am a little at odds with you basing most of your arguments on "you are not a special cookie, but average" but when it comes to TDEE calculators, you say it is just an average and shouldn't be taken for granted. I mean, in the end it is an estimation and that is the reason why you need several weeks of experimenting to see what seems to result in weight loss, and what doesn't. I don't think you were meant to discredit the method, I just think you could've differentiated more.0

you're right, there is a bit of a contradiction there. Perhaps I should have worded it a bit differently. What I was trying to say was that the TDEE calculators don't take into consideration all of the factors that really determine your TDEE, because if they did they would be too complex for most people to use. Aside from that, a lot of people use them incorrectly. So, they are estimates that work (somewhat) for average people, but they are not precise. I often read posts like "my TDEE is 2000, so I'm eating 1600 calories per day to be at TDEE-20%". But... what if that TDEE is off by 200 calories in either direction because it has no idea if you are a marathon runner or have been 200 lbs overweight for the past 10 years? what if the person using the calculator is in between the "buckets" of activity level that the common calculators use, or worse (and perhaps more commonly) they choose the wrong one? Any of those situations would drastically affect the resulting number. So many people want to be so tight with their intake and exercise numbers, but base it all off of a number that just simply cannot be correct to begin with.I am a little at odds with you basing most of your arguments on "you are not a special cookie, but average" but when it comes to TDEE calculators, you say it is just an average and shouldn't be taken for granted. I mean, in the end it is an estimation and that is the reason why you need several weeks of experimenting to see what seems to result in weight loss, and what doesn't. I don't think you were meant to discredit the method, I just think you could've differentiated more.
comparing that with the "not special" argument isn't exactly fair, IMO, but I can see why you drew that connection. What I was trying to say with the "I have a slow metabolism" point is that there is really no such thing as a "slow metabolism". Really, there is no such thing as "a metabolism", but that's picking nits. There are factors that affect your metabolic rate, and the effect is large enough to make TDEE and BMR calculators inaccurate, but those factors affect everyone in pretty much the same way (and none are accounted for by online TDEE/BMR calculators). There are exceptions for certain diseases and genetic conditions, but they generally aren't very prevalent nor do they have a very large effect. I was attempting to say that pulling the "slow metabolism" card is *generally* just a feel-better cop out.0 -
love it ... the 'you are not losing weight - or in extreme cases you are gaining weight - because you are not eating enough' comes along every day at least a handful times
can I just make an amendment to the gluten/wheat point: Since not all gluten is found in wheat and wheat is not just composed of gluten it is possible to have problems with wheat, but be alright with other sources of gluten. Irritable bowel syndrome (IBS) has often a low FODMAP diet prescribed (by doctors) as treatment and that includes cutting out wheat (because of it's fructans rather then gluten). Furthermore there are other bowel problems that get relieved when the sufferer cuts out gluten (or dairy) even if they are not intolerant to it. Gluten does not cause these bowel problems, but in order to properly heal it is recommended that gluten is cut out (it's prescribed by a doctor along side medication so not just quack science). And lastly it is also possible to be allergic to wheat without necessarily going as far as anaphylaxis. If people feel ill after eating a certain type of food they should always check with their doctor for further tests :-)0 -

Joshdann - so how do you measure your fat mass by 31 kg? I'd like to know pls.
Also were you saying that it is possible that we cant really trust the calculators which could include the MFP calculator, and that it is possible to adjust the MFP calorie calculations by maybe 100 calories more or less than it recommends if what MFP calculates is showing results in weight loss or not?
My favorite is your #1 on that list. It proves something that I secretly have been feeling is right for many years listening to all the people claim "diets dont work" and they eventually have to resort to tearing up their body with weight loss surgery. There are people who say "I'd have it again in a heartbeat" and who have had good results, but then there are those who have had disasters with it and are suffering intensely and then eventually eat out their surgery and are back to where they were before weight-wise, but now their innards are totally destroyed... i mean to say - if people could, would they really go for the WLS if they could do it on their own easily? they say "diets dont work" when all it is - is calorie reduction for the most part. its easy but yet hard to actually DO that. but its a lie. diets DO work. we have many success stories here. its that people dont continue to do the work and start eating back their old habits. i mean semantics-wise, diets dont work.. but making an eating-lifestyle-change will work. like we do here on mfp. wow... so think about it... if all the people who went thru the torture of WLS would have come to MFP and did the work and followed it, they COULD HAVE AVOIDED THAT !!!!0 -

Totally agree with almost all of this. Yes, let's face it if you stick to almost any diet you will loose weight. however I really do think that the psychological support behind certain plans may help some people more.
I agree that all you say is how I should think and how my husband would certainly think. Practical, science, engineer mind without the dare I say female psych.
So, yes no mystery except, life, family, psych, pat, vulnerability, fear and pressure.
Logically Iam a size 10. reality a size 14.0 -
i am down with everything you are saying except four ...I dont really see how you can build muscle in a 500 calorie deficit. My understanding is that you need energy to build muscle, and while in a calorie deficit, you are also in an energy deficit. Other than that, I love this post...so much BS on the threads...0

Allow me to horn in on these questions.Joshdann - so how do you measure your fat mass by 31 kg? I'd like to know pls.
Calipers are the most cost-effective way to measure; a hydrostatic test is more accurate, but a lot more money.Also were you saying that it is possible that we cant really trust the calculators which could include the MFP calculator, and that it is possible to adjust the MFP calorie calculations by maybe 100 calories more or less than it recommends if what MFP calculates is showing results in weight loss or not?
The calculators for BMR, TDEE, exercise, and so on are similar to BMI - they're accurate across populations, but only an average for n=1 cases. They provide a good starting point, but they're not enscribed on stone tablets.
Let's say due to metabolic and other factors your TDEE is 10% off from the calculators, a caloric change of 200 - that's a difference of a half pound a week of weight changes.0 -

Love it all, well said, except
Plateaus do happen, all of the guys in the Minnesota Starvation Experiments hit one in the final 4weeks of the starvation period, and could not be made to lose more weight even though it was tried and they were put on less and less calories.Plateaus are not "just a part of weight loss", they are usually either a failure in diet and exercise plan adherence or failure to properly adjust one's diet and exercise plan. Blaming that plateau on something else, or even accepting it as normal, will only slow your progress.0 -
Cliffs?0

The biggest falsehoods are "I'm experiencing X, therefore X is the truth for everyone" followed closely by "that doesn't apply to me, we are all different".
The balance is not in either statement.
Yes, plateaus are a phenomenon mostly generated by improper adherence and inconsistency in diet and/or exercise. But they are very much a real experience - people do see weight loss plateau and stop and the reasons vary. It seems that you make the assumption that one just "needs to stick to the plan" and everything will be resolved. Except this clearly ignores the simple fact the adherence (you have problems with "discipline"?) is a multi-faceted element that touches on emotional and physiological interactions. Why do binges occur? Why is adherence hard? Why do most diets fail?
"You have no discipline" is not only patently false but not helpful. Inconsistent discipline in most things is a fact of life as priorities change or get impacted by external influences - how well one adjusts to them matters.
Eat more to lose weight actually works for many people if it reduces cravings and increases adherence and provides sufficient energy to perform. Your rapid loss project is not the way everyone needs or wants to go. I'm quite comfortable at my very slow recomp as I eat food I enjoy. And that enjoyment is part of the lifestyle I want to life. I would not stick to it long term if I was eating 1200. Adherence and satisfaction can be key long term elements for many.The same goes for people who swear that even for obese people, a specific number of lbs per week is the maximum "healthy" rate of loss. There is no science to support that exact number. There *is* science to support the limit of roughly 6% of your body's fat mass per week as an upper limit on the rate of fat loss.
Actually not true. There are a lot of possible complications due to rapid weight loss - from pituitary damage to gall stones. Nutritional needs are a lot harder to meet at larger cuts. When we see people on the boards complaining of hair loss or other medical issues due to hard cuts, it is incorrect to tell then there isn't medical reasons to increase calories.
As to the 6% number, that science is based on a weak interpretation of studies from the 50s. Would suggest you review the source of that one.Another good example is the "your problem is that you are addicted to the scale" argument. Preposterous. There is nothing wrong with weighing yourself every 5 minutes if you want to. All data is good data.
Misses out on the psychological aspect of weighing oneself all the time. Obsessing over weight can result in adherence problems. That you don't doesn't mean others don't.Your metabolism is not by default faster or slower than everyone else's. It just isn't. Your level of physical activity, your diet, your current state of and/or history of obesity, and your overall size and frame do affect your metabolism. But yours is going to be pretty much the same as someone else with the same background and stats. As with all things, there is some variation within those groups, but it's not a significant amount.
Metabolic variation exist and are significant. We are just beginning to understand this.
Suggested start ... http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2581785/
Variations can be well above/below 20% estimated although LBM weight remains the largest indicator of change.footnote - Adaptive Thermogenesis

Adaptive Thermogenesis is, when simplified, a reduction in overall body temperature.
Already dealt with this in an entire thread - AT has a variety of other elements which you are chosing to ignore.
Overall you have some great info but I suggest temperance in that your experience or method might not suit everyone.0 -
