My family took care of the developmentally disabled, including at times people with Prader-Willi. I think every Prader-Willi person in independent living had to have their refrigerator and pantries locked against use, and their food portioned for them by staff. Seems like there would be no point to it if the people could just gain weight without it being related to food intake. I always wonder how familiar with the condition are the people that use it as a some kind of metabolic disorder that defies nutrition science.paperpudding wrote: »Prada Willy syndrome does not disprove CICO - it is a syndrome where people's hunger cures are out of whack
( amongst other traits such as intellectual disabilty) - and thus they eat way beyond what they need.
If their access to food is restrained, they maintain weight in the same way everyone else does.
If anything, the related disorder of Pica - eating nonfood objects - is closer to defying CICO. Sure, rocks have no calories, but sure, if you eat a pound of them, you're going to weight a pound more until you have a very unpleasant bathroom trip, stomach pump, or surgery. Or if eating dirt, the potential parasites could definitely make a difference between calories in your mouth and calories into your actual system.4 -
That as well as not all medical professionals give good advice.
About a month ago, I found out that someone who was an ROTC cadet with me as an undergrad and went on to Medical School is now on QuackWatch for some questionable medical advice offered to clients.
The anti-vax, anti-mask, etc is not limited to the uneducated. There are plenty of educated people who also buy into such pap.
In general, not commenting on any specific advice here, just because Doctor with Credentials advocates something doesn't mean it's good advice.paperpudding wrote: »I suppose those of you who disagree know much better than my medical advisers.........................................

Just today somebody said their doctor had told them to stop taking all their medication - there was no record in the patients notes of this and the doctor confirmed he had said no such thing.

When one has Hashimoto's, use mfp which for my height allows 1200 as lowest safe calorie limit it was impossible for me to loose weight. I needed to improve the many food intolerances and other symptoms which were causing additional damage to my health from the originally dismissed then inadequately, ineffectively treated Hashimoto's which had caused my body so much damage over the years. There are many different forms of autoimmunity with differing levels of autoimmunity within the community, mine was dire. The range of foods I could eat without increasing my symptoms was minimal.
You may not like it but some of us do have difficulties because our bodies are so damaged for reasons other than self intended abuse. Eating Less and moving more does not always cut it. I knew there had to be more to my life than what was on offer with the practice I had been with for years.
Having taken other advice with full testing I changed away from standard t4 which in this country (uk) contains dairy as one of the binders in pill form which is one of my diagnosed issues, in liquid form it contains paraben another of my issues. (paraben is a food preservative and is hardly ever on a food contents list). I lost and kept off 7 stone for many years. FYI. I did not need to count calories, the weight came off because my body was then working as it should.4 -

Nothing you are saying disproves CICO or eat less, move more. Whether or not you were able to lose weight at 1200 calories cannot be determined unless your food was being controlled under laboratory conditions. It is common even with logging to be off 20 percent or more.
For the sake of argument if you were unable to lose weight at 1200 it still doesn't disprove anything because it would just mean in your unique condition you would need a medically supervised VLCD to lose weight. There is no amount of damage to your body that can make it create energy from thin air. If you take in less food energy than you need to sustain and move yourself you absolutely must used stored energy to cover the deficit. There is no way around it.
I am glad you were able to get the help you needed and it resulted in weight loss. I hope as you tell your story to others it serves as a hopeful message not one that makes them doubt the true science of weight loss.9 -
Obviously there is a simplistic view of the depth and breadth of damage to someone's life that undiagnosed, untreated, then ineffectively treated Hashimoto's can cause a persons body. Every system in my body was affected, because the endocrine system is supposed to work in unison. When I go into town I see others with similar, probably dismissed difficulties. For me it actually took comprehensive endocrine system support for me to still be here, others are not so fortunate. I'd been told there was no treatment for me by my local NHS providers, they could not put me into any of their permitted boxes. At Regional NHS Immunology, higher up the NHS hierarchy, they told me what I needed, yet the local funding practice refused me that care!
I've heard recently, VLCD supervised regimes are about to be offered or are under consideration for some diabetics over here. Under any measures they would use, I and others like me, did not, could not, would not have fulfilled their requirements to be considered let alone accepted. I was and still am not diabetic nor are others with similar issues. Nor are we freaks, nor snowflakes. As I wrote in my first post on this thread, "there are people in this world who need to repair damage to the bodies systems", viewed as a whole before they have a chance of regaining their "health", epitomised for the general public as the Holy Grail of Loosing Excess weight.
Truthfully all I wanted was to be able to do was to live the active life I knew was possible. In the end, the weight did not matter, I'd accepted I was as I was the size I was. I wanted to be able to breath, to have stamina to have fun. Not to need to throw up on smelling someone's fowl laundry residue, perfume or aftershave, if not being convulsed into coughing bouts by the feted air in a concert or school halls for grandchildren's performances, I sometimes had those reactions even in the open air too. I wanted to play with the children be part of their lives. I wanted as others do, to LIVE.
All most of the population understands is weight loss, weight loss, weight loss, NOT the need for a good quality of life. I'm speaking for the others who are as I was, who have more Life affirming goals of better health which are often withheld from them, (at least over here) for lack of proper medical support, people for whom losing weight is the last thing their systems are able to cope with given the present state of their endocrine system and/or implications of other autoimmune conditions, a body needs to work properly before it can behave normally.
If you have a properly functioning body which conforms, be thankful.2 -
If eating less and moving more was that simple and worked, no one training for a marathon would be overweight, and ive seen plenty of overweight runners. I was one, living on calorie deficit, running, working out, doing ultrathons. Its not sustainable. You'll lose weight in the beginning, but you'll gain it back unless you luve your life in a calorie deficit. Many people actually under eat. CICO works, but yiu need to have a healthy metabolism and no underlying health issues for it to work properly. I've undereaten for the last couple years and have consistently gained weight. Now I'm with a trainer that has me on a reverse diet, adding in 500 calories a day.1

Actually the problem is you did not know your numbers.
You knew estimated numbers you used for math.
But not your real numbers.
You can mess up the CO part by the level of CI you attempt to do - and while you could have been burning many calories on the running your body can adjust to the foolishness of too much deficit and lower the CO for other aspects.
Just because you didn't have correct numbers doesn't mean the facts aren't true.
You were eating more than you were burning if you were gaining FAT weight.
But many reasons to gain water weight which many people have misunderstandings about.
You can have very terrible metabolism (by that I mean not where it could be because body has adapted) and still eat low enough you will lose fat weight.
You'll also be massively stressing out your body - but it will lose fat. And muscle.
Sounds like you did that - hence eating more. Eventually you'll be in good spot to lose weight reasonably.

that seems a complete strawman to me - all most of the population understands is not weight loss, weight loss, weight loss at all.
Almost everybody understands the need for good quality of life, separate to one's weight.
The medical system where you live may or may not provide good care for your medical issues - but that in no way disproves CICO nor means you could not lose weight if you ate less than you burned.
Your claim to special snowflake status - it is just impossible for me to lose weight because xyz special reasons - seems very tenuous to me.9 -

I am not downplaying what you have gone through. In the context of this thread though it doesn't change anything. Even while you were suffering your heart beat, your lungs filled with air, and the rest of your organs maintained your life. Presumably you moved around some as well. All of this requires energy which had to come from somewhere.
If you were too ill to lose weight in a normal healthy manner that is another issue. It doesn't mean that CICO doesn't work. It just means that at the time it may not have been advisable for you to do it. It also doesn't mean it was impossible.
It is a comfort to know that once you determine your caloric needs that eating less forces weight loss. There are a lot of people still out there suffering. They may not suffer to the same degree you have suffered but that doesn't make their suffering go away. They need hope. They already have a lot of doubt. They need to believe if they keep putting one foot in front of the other they will move forward towards something better. One of the hardest things to get people to do is to trust the process.
I have never known enough of the population well enough to know what they understand about weight loss. Making assumptions about what they "know" is folly in my opinion. I know from my Larger Losers group here at MFP that quality of life is EXTREMELY important to people who have a lot to lose. It was extremely important to me. My life was a prison of fat. I was in constant pain. Everything was a challenge including just lying in bed to sleep at night. I also had a convulsive cough that was easily set off. Even the slight variance in air pressure inside a vehicle could get it started. It was so bad that it scared people who heard it and it more than occasionally ended in vomit.

Actually, lots of people find that training for a marathon dramatically increases their appetite. It's not at all surprising that there are overweight runners as it is VERY EASY to gain weight while running for many people unless deliberate steps are taken to control food intake.
I have been running marathons since 2016, sometimes multiple marathons a year. I would absolutely gain weight if I wasn't also counting calories, as even my longest training runs don't burn as many calories as I could eat if left to my own, uncontrolled, devices.
You don't have to "live your life in a calorie deficit" to maintain your weight. All you have to do is consume the number of calories your body needs given your activity. It's a very simple concept that is often very hard to consistently implement in practice as our bodies will sometimes signal hunger to us when we don't actually "need" food and our minds will sometimes encourage us to keep eating (especially the hyper-palatable food many of us are surrounded with) even when we aren't especially hungry.
I find my current way of life (running a lot, counting calories, maintaining my weight) to be very sustainable. Been doing it since 2015. Would it be an ideal fit for everyone? No. But it works for me. It's a path, among several, to the ONLY route to consistently maintaining a healthy body weight, which is to consume the number of calories that your body requires.10 -

i think you under-estimate just how quickly runger can make you wolf down a few thousand calories of extremely-calorie-dense pub food..and many, many group runs end at pubs. (You also don't know how long they've been running for - it takes years for weight to come off at a reasonable rate).3 -

(a burger, fries, and a beer can easily get to 2000 calories (ETA: less for a simpler, smaller burger, but most pubs have pride in their work; also less if you don't get the really good beer)...I am definitely hungry enough to wolf that down in a blink of the eye after a long run.... alas, it would take 27 miles to burn it off).7 -

When I lost most of my weight from tracking years ago (I lost like 30 through exercise over two years but didn't track and then lost 50 more after tracking), a lot of my family was like, "how did you do that???". When I said just by tracking and moving more, it was like "nah, won't work for me. No way!".
Alrighty then. Whatever you want to believe.
Regarding running (or any serious endurance cardio), I started running years ago and ran for like 6 years and moved to rowing when my knee couldn't take it any more. I'm always stunned, to this day, at just how much I can gain while burning 600 to 900 calories a day. That's two large PB&J toasts and I'm net even on the day. And I can eat some PB&J with the best of them!3 -
CICO doesn't work. It all depends on where you live.
Fact 1. When I moved from my first house to my second house I gained a lot of weight and was unable to make lasting progress the entire time I lived there.
Fact 2. Shortly after I moved to my third house from my second house I began losing weight and I am now at the lowest weight I have been since I was a teenager.
The above did happen and, in fact, moving did help me lose weight. A change of environment away from the place I had a lot of bad habits at the time I was ready to form some new better habits was an aid. I do not think it would be a stretch to find studies that show that a change of location at a critical time can be beneficial. I didn't move to lose. It was just good timing.
What I have done with the above is taken 2 facts and attributed more to them than I should. Having an aid is great. Having a hindrance sucks. Like most people I had some aids and some hindrances. None of that changes the physical process of losing weight which is forcing your body to use stored energy. This has been summed up in the energy equation known as CICO.
CICO is not calorie counting. It is not even weight loss. It is an energy equation. It is how you gain or lose stored energy. If most of your minimal gain days balance out with your minimal loss days you are in maintenance.
If your body can run on something other than food energy and stored energy then what is keeping it from taking every calorie of food energy and converting it to fat?10 -

When it comes to people in my life I do not offer advice unless I am asked. Sometimes this bugs me because I can see the mistake but I say nothing because it is not my place. So after months of watching someone exercise A LOT and continue to gain weight I was finally asked what might help.
"STOP EXERCISING SO MUCH! IT IS JUST MAKING YOU HUNGRIER!"
I didn't actually yell it but this person does have pressing medical concerns. I went on to explain that if you do not have your hunger controlled by food first then burning 700+ calories a day has a good chance of backfiring. It seems like so many calories but that is only if you are making mindful choices. If you are not you can blow past that easily at any restaurant or in any well stocked snack cupboard in just a few minutes.
I told the person to scale it back for a few weeks, work on food control, then ramp it back up.
My advice has gone unheeded because food control is a low interest but I remain hopeful.6 -

Fact 2. Shortly after I moved to my third house from my second house I began losing weight and I am now at the lowest weight I have been since I was a teenager.
this anecdote and the 'but there are overweight runners' argument reminds me of the oft claimed point about diet coke " It makes you gain weight, lots of overweight people drink it"
All of the above have in common - taking one factor out of context and not seeing the whole equation.
In all these cases ,as with every other case, the outcome doesn't depend on one thing - if the total equation over time is calorie deficit, you will lose weight6 -

I don't argue with people. I don't argue because I have gotten so much science that's 50+ years old thrown at me as if it were STILL relevant. 21st century science is strongly supporting a hormonal theory to weight loss, not a calorie deficit theory. Intermittent fasting plays strongly into the hormonal theory because the goal of it is to allow your insulin to go down and glucagon to increase. We need glucagon to start the fat loss process (lipolysis)...if you're spiking your insulin 3-6x/day and have a 14-16 hour eating window, then you don't lose weight. The goal of intermittent fasting is not to reduce calories, per say, that's just a secondary effect. There's also the "starvation diet" thing to contend with as well. For most of the 20th century, 'starvation diet' was 1200-1500 calories per/day. Let that sink in a minute. Isn't that the GOAL for most of us??? Why?
A calorie is a calorie is a calorie----because physics, that's why. A calorie is the unit of heat needed to heat 1 kilogram of water 1 degree Celsius. Period. It's not anything else. Our bodies NEED to maintain a certain temperature...in fact, it's tightly regulated. The life giving chemical processes keeping us alive and healthy depend on it. These processes also depend on the pH of the blood to be between 7.35-7.45 and, thus, it is also tightly regulated. The human body's chemical processes that regulate these can use 2 energy sources: glucose and ketone bodies (hereafter: ketones). These energy sources are used in the Krebs's cycle which produces ATP.....which the cells use to do work (not glucose, not ketones). The aforementioned hormones, insulin and glucagon, are antagonistic hormones---meaning they have the opposite effects. The problem with glucose is that too much of it destroys tissue (blood), thus insulin. Insulin gets it out of our blood, usually by storing it as fat or putting it in cells for use in the Krebs cycle. When cells don't take in glucose, tissue damage happens or we get fatter. The A1C blood test detects the level of blood that's been 'glycated'....saturated with glucose. If this number is above 6.5, it indicates Diabetes type 2. 5.6-6.4 indicates tissue damage is occurring but not technically diabetic, yet...it's called insulin resistance/pre-diabetes. While insulin is in the blood, glucagon is not. Meaning, no fat loss is possible----calorie deficit or not. Now let's talk about glucagon.....
Glucagon is absolutely needed for your body to access the fat stores in your body. Increasing this hormone by fasting (regularly or not) is how fat loss happens. If you don't eat, your body still needs to maintain it's temperature and ATP still is needed by cells of all types. Enter Ketones......they come in at a different point in the Krebs cycle to produce ATP. In fact, they produce more ATP than glucose. So the issue with ketone bodies is 2-fold: raising body temperature excessively and acidifying the blood. In normal people, once the blood pH hits 7.35, insulin is called into action to stop the production of glucagon. The blood pH normalizes and the process occurs again, assuming you don't eat. This also stops fat loss by making the liver produce glucose from it's stores of glycogen or from a process called gluconeogenesis---the making of glucose. It's a medical and physiological fact that the human body does not need to consume any carbohydrate to produce glucose....the liver is fully capable of producing 100% of the glucose needed by the body....even your brain's needs can be met without consuming carbs. Ketones can supply up to 85% of your brain's energy needs....your liver's glucose, the other 15%.
Sorry for my long response...but I need you to understand that the lady in the gym was probably worried about her hormones to lose fat and get fit.....which is 21st century science with a few Nobel prizes backing it up.1 -

If you don't eat, your body still needs to maintain it's temperature and ATP still is needed by cells of all types. Enter Ketones......they come in at a different point in the Krebs cycle to produce ATP. In fact, they produce more ATP than glucose. So the issue with ketone bodies is 2-fold: raising body temperature excessively and acidifying the blood. In normal people, once the blood pH hits 7.35, insulin is called into action to stop the production of glucagon. The blood pH normalizes and the process occurs again, assuming you don't eat. This also stops fat loss by making the liver produce glucose from it's stores of glycogen or from a process called gluconeogenesis---the making of glucose. It's a medical and physiological fact that the human body does not need to consume any carbohydrate to produce glucose....the liver is fully capable of producing 100% of the glucose needed by the body....even your brain's needs can be met without consuming carbs. Ketones can supply up to 85% of your brain's energy needs....your liver's glucose, the other 15%.
Sorry for my long response...but I need you to understand that the lady in the gym was probably worried about her hormones to lose fat and get fit.....which is 21st century science with a few Nobel prizes backing it up.
So, how ya figure people lose substantial weight and keep it off, without IF?
Because we do.13 -
Add me to that.
Have done no IF ever and am more of a graze on bits throughout the day person - and yet miraculously I have defied this 21st century science and lost weight and the maintained it for another 6 years. !!!!!
Sorry for my short response - but your new 'science' is nonsense.
CICO is as relevant today as it was 50 or 500 years ago.
Human body hasn't changed and basic physics hasn't changed.8 -
"if you're spiking your insulin 3-6x/day and have a 14-16 hour eating window, then you don't lose weight."
That's funny as I tend to do IF in the winter when my calorie allowance is smaller and gain some weight and then in spring I eat far more frequently and lose that weight again despite "spiking" my insulin with high carb drinks and foods very frequently because I have a very high calorie allowance.
Must be because I was born in the 20th century that "21st century science" doesn't work.
Hmmmm.9 -
My body overproduces insulin when I eat so I "spike" more than your average person. I lost weight when I took in less energy than I needed to live and move forcing my body to use reserves.
The human body operates the same way in the 21st century as it did in the 1st century. The key difference is that in the last 2 centuries weight loss "science" and amazing "breakthroughs" have gotten to be far more lucrative.
Insulin is the new grapefruit diet and so far IF is really only amazing for people with IR and rodents. Outside of being a useful tool for some to more easily stay in a calorie deficit, of course.7 -

Who has gotten these Nobel prizes that you think are backing up your incorrect 'science'?4
