Do you believe in strictly Calories In - Calories Out?

lindsey1979

When a person has surgery, the dieticians put patients on a higher protein diet to help them heal, not on a coke and doughnut diet.

urrrr....ummm.....what on earth has that to do with CICO?

Because this is the way the "clean eating crowd" tries to prove they're right and IIFYM is wrong. They completely ignore everything about CICO or IIFYM and pretend that all people practicing moderation just eat junk 100% of the time.

Clearly that wouldn't work. No one is saying that would work. It wouldn't fit any macros, thereby negating the entire principle behind IF IT FITS YOUR MACROS.

What they create is a strawman argument that is easy for them to tear down. Unfortunately for them (and luckily for us) they're only winning an argument of their own creation.

Yes but don't you realize that by its very name -- If It Fits My Macros -- acknowledges that not all calories are the same. Otherwise, it would be IIFMC -- If It Fits My CALORIES.

The same for what? Is anyone actually arguing that they are the same for all purposes and not just for the energy they contain for CICO purposes?

I haven't seen that claim yet, and can't imagine someone making it, but no doubt the other side of this argument will say that they have...

...and likely frequently too.

Okay, here's one from a few pages ago:

"Calories in - calories out is 100% correct. For weightloss. However if you want to be healthy, you also want to make sure your macros are good too."

I argue that CICO is not the only thing important for weight loss. People here love to make the differentiation between weight loss and being healthy, but they overlap. How you lose the weight (i.e. more fat versus muscle) will impact the amount of weight you lose since 1 lb of fat takes a much bigger deficit than a 1 lb of muscle loss. Then, of course, there is the metabolic results of higher body fat percentages. Then, there is the way you feel and how sustainable the plan is in the longterm. All those things contribute to weight loss and not just health. They're linked. Trying to separate them see silly and foolish to me.

Okay, then how do isocaloric diets (with the same caloric deficits) result in different weight loss? If it's all CICO, then the macros shouldn't matter and the results should be the same.

Because the measured calorie expenditure, hence deficit, can only ever be an approximation. Lots of different factors are going to affect expenditure, which will lead to absorption of energy by the body to be less than forecast, far fewer lead to it being greater than forecast.

The key point in your statement is different weight loss, yet upthread we've got people claiming a significant deficit yet gaining weight. Not going to happen, unless they're storing solar energy and wind power.

Sure, but mathematically, you can imagine a scenario with the right numbers manipulation where someone could gain or stay the same whereas another lost -- you'd just have to shift the bar for the calculated deficit closer to maintenance.

But different weight loss is the whole point. If all calories were created equal and quantity was the ONLY thing that matter, then the results would be the same. Since they are different, there is another factor(s) at play that are not accounted for in sheer caloric value.

This is still just variables in the CO portion. It does not negate the fact that you need to be in a caloric deficit to lose fat.

Once again, not my point. I'm not saying that you don't need to be in a caloric deficit, but how you manipulate that deficit will make a difference in your weight loss. So, it's not all about sheer caloric value -- otherwise, results wouldn't differ, and they do.

Am I not saying this clearly?

I think I have pretty much understood what you are saying (and generally do not disagree) - however, in a thread where some people try to indicate that you can gain weight on a deficit, I think it important to make the point that it is not what you are saying.

Also, I wanted to make it clear that results differ mainly when you look at people with metabolic issues. When you look at populations when they do not have them (and even in conflicting studies where they do to be honest), then results do not differ significantly.

I agree that people who think CICO is totally invalid are way off, so I totally agree with you wanting to dispel that notion. But, on the flipside, there are a LOT more people that I've seen that say CICO is the ONLY thing. And I'd like to dispel that notion as well.

As I said before, I think they're both important parts of the weight loss puzzle for people.

Both important, but all calories are not equal how they effect blood sugar and uptake.

Are you kidding me right now?! Did you just say that you agree that CICO is important for weight loss, while macro counts are important for optimal health?

Because that is what EVERYONE in this thread has been saying.

No, I never said that calories are not important, what I said is that I do not believe in CICO.

...but what does that have to do with CICO?

The point being it's not CICO, but many factors.

For example if you have Hypothyroidism, will cause you to gain weight with the same calories you were eating previously.
Another example is when you get pregnant.

Conditions that change what your CI is relative to what it says on the side of a food box is not somehow an invalidation of CICO, it just means that what your CI is can be individual based on your own metabolic rates and has to be discovered by each individual through meticulous measurement and tracking.

To give an analogy picture a bunch of people who are trying to determine the speed of a vehicle. Speed is distance over time. They all have the same ruler but they have different watches and each watch measures time slightly different...one is faster, one is slower etc. They all disagree on the speed of the car.

Does this mean

A) that using distance over time to measure speed is wrong
that their measurement devices include a variable that they aren't accounting for

What exactly do you not believe?

Do you think that you can gain weigh on a caloric deficit?

stevencloser

Yes, CI can be affected by obtuse factors like excretion and poor metabolism, but it will never become a larger amount of energy than it contains.

That's really poorly worded but my head hurts so screw it :P

And that's really the point - factors can and do affect both CI and CO, but at the end of the day if CI is less* than CO weightloss WILL occur.


*scientifically, not just assumed to be

None of the rest of this discussion invalidates that.

Exactly. What is on the food box is the maximum amount of energy that can be obtained by the food in a 100% efficient system. Our bodies will never actually reach that efficiency and some people might get less calorically than others from the same foods. That said you would NEVER get more calories than what is stated on the box.

Having some major digestive issues or a tapeworm does not somehow invalidate CICO though, just means your CI is much lower than you might expect from what is written on the box.

Not 100% true, the numbers on the box are just an average too, so the actual amount could be higher. So you could technically absorb more calories than stated on the box, but never more than the food actually contained.

True, but if you can't really determine the numbers, then you have to do more to cover that margin of error. And regardless of that, isnt' everyone interested in figuring out the most effective way that works for them? If lowering or raising their carbs, depending on the individual, results in greater, more effective results, doesn't everyone want to know that?

Doesn't everyone want to maximize their efforts? Get the most bang for their buck? And, isn't finding the most effective way what will lead to the most sustainable longterm changes?

Whoa, 16 pages, That has to be a record! These kinds of threads always spark the best debates! My answer to question #1 is no! I don't lose weight if I eat crap, I lose more when I keep it cleaner, but I do have a friend on here that eats whatever and she loses too, so I think it's whatever works for you!

I lost 18 pounds in 35 days eating quality foods.

Okay. Can you define what you mean by CICO in your own words because I cannot help but feel that you think it is something that it isn't.

SingRunTing

Calories in - calories out is 100% correct. For weightloss. However if you want to be healthy, you also want to make sure your macros are good too.

I think this says it all... end of argument.

Not all energy is created equally.

Conservation of energy: energy cannot be created nor can it be destroyed. It can only change from one state into another.

Also requires a closed system. The human body is not a closed system.

But humans can only gain energy from eating. So as long as you use more energy than you're eating, mass will decrease. If we could absorb energy from wind or sunlight, then we'd have a problem with CICO being invalid.

Yes, but both sides of the equation are affected by (1) how much food is actually absorbed -- that throws off your CI part and (2) other energy expended that's not fully captured, like heat, on the CO part. We try to measure those as much as we can through the caloric value of food and things like RMR testing, but it's not fully accurate.

That's why most people estimate their CO by looking at their weight loss results and working backwards. But there is a lot of error there since 1 lb of fat creates about 3500 calories of energy and 1 lb of muscle creates somewhere between 600 and 1700 calories. So, even when you lost 1 lb, there is not a great way to reverse engineer that calculation. Then you have issues about how your macros result in different weight and fat losses, which makes the calculations even more of educated guesses.

How much food is absorbed can only go down from the amount of calories you eat, which is good if you're trying to lose.

Btw. I read through your study completely now. As said, the ones who lost least lost about as much as was expected. Their conclusion about the ones who lost more lost weight because "we don't know, maybe TEE or more burn from being more active, or undereating, maybe something to do with something someone else noticed that some people's calories burned while sleeping would change significantly on different diets. Tl;Dr;: there has to be more studies done"

This.

Plus the sample size was really small. n=6 isn't adequate to get meaningful results. Maybe some people exercised more than others and didn't mention it (they felt better and so moved more). Or maybe TDEE was miscalcuated for a few people. Or maybe some people were using measuring cups instead of a food scale. Or maybe some people were just guesstimating serving sizes. When a study is performed in a non-controlled environment (the subjects weren't kept in a hospital or anything, they were at home) and the sample size is small, the results are pretty null.

I'm not saying that the conclusions aren't true. But they need to do a better controlled study with more people to validate it.

Are you kidding me right now?! Did you just say that you agree that CICO is important for weight loss, while macro counts are important for optimal health?

Because that is what EVERYONE in this thread has been saying.

I think it might just come down to her reading comprehension being way off and she thinks we are saying something we aren't.

Going to make this very clear. CICO is all that matters for weight loss specifically. For health and for nutrition and for wellbeing yes of course what you eat matters. What you eat matters for weight loss in the sense that to sustain weight loss you have to sustain your health so to have a sustainable diet for weight loss then yes what you eat matters...but not because CICO is incorrect.

And this is what I think is silly -- this decoupling of the amorphous "good for your health" and weight loss. They're linked. One will affect the other, either in how much fat versus muscle you lose, overall lbs lost, how you feel, how you sleep, how your hormones adjust, how manageable the program is for you, etc. -- that will all affect your ultimate weight loss and body composition goals. To pretend that they're totally different things to me is an issue of not being able to see the forest for the trees.

Whoa, 16 pages, That has to be a record! These kinds of threads always spark the best debates! My answer to question #1 is no! I don't lose weight if I eat crap, I lose more when I keep it cleaner, but I do have a friend on here that eats whatever and she loses too, so I think it's whatever works for you!

I lost 18 pounds in 35 days eating quality foods.

Nope all calories are not created equally!

YOu lost weight because you were eating fewer calories than you burned. its that simple.

Yes, CI can be affected by obtuse factors like excretion and poor metabolism, but it will never become a larger amount of energy than it contains.

That's really poorly worded but my head hurts so screw it :P

And that's really the point - factors can and do affect both CI and CO, but at the end of the day if CI is less* than CO weightloss WILL occur.


*scientifically, not just assumed to be

None of the rest of this discussion invalidates that.

True, but if you can't really determine the numbers, then you have to do more to cover that margin of error. And regardless of that, isnt' everyone interested in figuring out the most effective way that works for them? If lowering or raising their carbs, depending on the individual, results in greater, more effective results, doesn't everyone want to know that?

Doesn't everyone want to maximize their efforts? Get the most bang for their buck? And, isn't finding the most effective way what will lead to the most sustainable longterm changes?

For yourself, and I, perhaps optimisation is a concern. But I think your time spent on this forum should make it apparent that most people just want to lose some weight, and don't really care for the science or faffing around with numbers

So, that's another example of how the CI part of the equation can greatly affect your weight loss success that is not wholly accounted for it its caloric value.

Avoiding the validity or otherwise of the specifics, some of what you eat may cause you to want to eat more. That's fine, but if you do eat more then you're ingesting more calories. Doesn't invalidate the energy balance point.

Once again, not trying to invalidate the energy balance point. Just make practical suggestions based on known information. Getting into a physics purist argument is not my point. Getting into what helps people lose weight most effectively is, and that's why what you eat is going to be more important than just its sheer caloric value -- not only to your health, but also to the success of your nutrition plan and your actual results.

I know that this is continuing the 'off point' sub conversation, but it can work both ways, as in higher carbs can actually help fat loss indirectly. Someone who is not insulin resistant often does well on higher carbs (and this assumes appropriate protein and facts for health and LBM retention). Carbs provide energy, energy fuels workouts, workouts encourage LBM retention/gain and better nutrient partitioning.

Totally agree. And that's a really important point for insulin sensitive people to know and why they should probably avoid low carb diets. And why people have such dramatically different reactions and results from high carb and low carb diets.

ON a low carb diet you eat protein, vegetables, fat, some fruit, nuts, cheese. This is a great diet in my opinion, and not a diet to avoid.

That's a horrible one for me.

At least she gets credit for saying "in my opinion" for the first time ever I think. And yes, that's a horrible diet for me as well.

As already has been stated several times Calories are a unit of energy - 1 calorie is the amount of energy needed to raise the temperature of a l of water by 1 degree c. how on earth can they not be created equally? you boggle my mind.

Calories in - calories out is 100% correct. For weightloss. However if you want to be healthy, you also want to make sure your macros are good too.

I think this says it all... end of argument.

Not all energy is created equally.

Conservation of energy: energy cannot be created nor can it be destroyed. It can only change from one state into another.

Also requires a closed system. The human body is not a closed system.

But humans can only gain energy from eating. So as long as you use more energy than you're eating, mass will decrease. If we could absorb energy from wind or sunlight, then we'd have a problem with CICO being invalid.

Yes, but both sides of the equation are affected by (1) how much food is actually absorbed -- that throws off your CI part and (2) other energy expended that's not fully captured, like heat, on the CO part. We try to measure those as much as we can through the caloric value of food and things like RMR testing, but it's not fully accurate.

That's why most people estimate their CO by looking at their weight loss results and working backwards. But there is a lot of error there since 1 lb of fat creates about 3500 calories of energy and 1 lb of muscle creates somewhere between 600 and 1700 calories. So, even when you lost 1 lb, there is not a great way to reverse engineer that calculation. Then you have issues about how your macros result in different weight and fat losses, which makes the calculations even more of educated guesses.

How much food is absorbed can only go down from the amount of calories you eat, which is good if you're trying to lose.

Btw. I read through your study completely now. As said, the ones who lost least lost about as much as was expected. Their conclusion about the ones who lost more lost weight because "we don't know, maybe TEE or more burn from being more active, or undereating, maybe something to do with something someone else noticed that some people's calories burned while sleeping would change significantly on different diets. Tl;Dr;: there has to be more studies done"

I agree about the conclusions, but I think the underlying facts are super interesting. And at least suggests that if you manipulate the deficit in a certain way, you can maximize results, so much so that they don't understand what exactly is happening. To me, that's pretty exciting.
