The notion of a metabolic set point is mostly a myth. The actual changes in resting metabolic rate from mild caloric restriction are very small. Most people underestimate how many calories they consume unless they carefully weigh and log everything.


Do you have a source for this? It's a fairly trivial Google search to find papers making the counter-claim, but I'm aware that nutritional science is kind of a dumpster fire, and much of the research is at least a couple decades old.


>The actual changes in resting metabolic rate from mild caloric restriction are very small.

But only a small change in metabolic rate can easily produce ten or more pounds of additional weight a year.


My reading of the last 3 years of findings regarding changes in resting metabolic rate due to caloric restriction is that they could become big enough to explain the pattern of weight regain. Now, the specific quantification of the relationship between amount, lenght of caloric restriction and resting metabolic rate is, in my opinion, waiting for a trove of data we do not have yet.


well, my doc is head of bariatric surgery at nyu, so I'll pass on what you said. Btw, I do weigh and log everything.

Your surgeon's income depends on people getting bariatric surgery. You can add in exercise to increase total calories burned to support a larger food intake and still lose weight.


(1) that’s not a meaningful support of any kind of argument. It’s borderline vacuous.

(2) I’ve never heard a bari surgeon Not recommend lifestyle change. Most will ask you to do your best pre-op, to make the surgery as safe as possible. They will counsel you on the same post-op. Many have in-house dietitians to assist.

(3) Your argument implies the following: Bari surgeons pretend and contend diet doesn’t work, to keep the supply of customers coming. Fact check: diet was failing for decades, and only the resultant epidemic made something as extreme as cutting out pieces of a non-diseased GI tract not entirely insane. Go read another hundred diet books of the week; proclaim their findings from the rooftops. I’m pretty sure the bari surgeons aren’t going to run out of willing customers.


I think the problem is that most people, and that includes doctors and bariatric surgeons alike, don't really know how to diet.

Using only diet, I have successfully lost 90lbs and continue to lose.


Good for you! I mean that. But your experience isn't everyone's experience. Mine isn't either. I said so. For one, men have much easier time losing weight. I'm not a man. I offered my singular experience to give support for those who might also be mystified after trying everything with a doctor. To those who think my surgeon is trying to get me to buy surgery by saying a diet won't work-- actually, my surgeon (also head of a weight loss clinic) recommended against surgery and against my eating less that I already do. There are a number of drugs that can help people trying to lose weight that aren't phentermine. Some people like me can't take them because of a family history of thyroid cancer or other diseases. But for those who can take these, they are helpful tools. Often, those who struggle with weight loss have struggled with it throughout their life for a host of reasons, only one of which may be eating and exercising habits. To the person who told me I could "add in exercise", what are you trying to accomplish with comments like this? Of course I exercise. People who struggle with this health issue need support and to know that there are other difficult cases sometimes and to keep at it anyway. I keep at it anyway, because being in shape and healthy matters to me and always has. I do an hour of cardio 5x a week and I weight train every other day. I was a serious athlete as a young person (high school/college) and never had trouble with weight gain/eating disorders. I definitely know how to add in exercise. In fact, I never didn't exercise in my life. When I hear simplistic comments like some of these that seem to be meant to shame someone for not exercising, or for having no willpower, or for just generally not being disciplined at losing weight, I have to ask myself where is this kind of thing coming from? I can't say for sure, but perhaps it is because they feel that way about themselves and it feels harsh to them so they throw it at other people so they don't have to deal with the discouragement. To these people I say: don't be too harsh with yourselves! You will do much better at all of these things if you support your own small successes every day. Ultimately, don't you want to succeed at being as healthy as you can? Well, you get there through encouragement and support of yourself. You get there hopefully with the help of better data, drugs, approaches, exercise, and emotional support as better and better research is done into weight loss. And this is what the OP was all about anyhow. One of the best things a person can learn from being an athlete is that if you have team support-- if you root each other on-- you raise the level of the team. People who are trying to lose weight, including yourselves, need this. Because the other raises cortisol levels, and we know what happens then.


I only have my own anecdotal experience to work from, but I genuinely believe that most Americans are so lost when it comes to diet that these last-resorts are all they have left.

I am very fortunate to have fallen in love with a Greek woman who has shared her family's diet with me. It's likely saved me from needing an extreme solution myself.

I think that in North America, we don't know the first thing about eating healthy. A big part of the Mediterranean diet is using high quality, expensive, olive oil with everything. My parents would blow a gasket if they knew that we paid for the fancy stuff. At $10/L it's more than my parents would ever spend, but it's honestly not noticeable as far as my budget is concerned. It's seriously a game changer.

By putting high quality olive oil in all you're food, everything becomes much tastier and satisfying than before. It allows you to eat and be satisfied with much less. The other key is to splurge on expensive, good looking vegetables.

Having delicious vegan recipes allows you to get your kicks without eating tons of saturated fats.

This allows you to be satisfied with less volume. It's made up through quality and taste. This is the foundation of a healthy diet, eating high quality tasty food.

The problem with the North American diet is that we don't have the same traditions of passing down recipes as they do in other parts of the world and so none of us know how tasty a simple dish can be. We then eat this processed crap that gets passed off as identical to the original when it's a fraction as tasty and nutritious. As a result, we compensate by eating far too much of it.

I think that this continent is in dire need of better recipes and respect for their ingredients. Until that gets integrated into the culture, we are doomed to depend on these extreme measures to stay at a healthy weight.

Don't get me started on drive-through culture or eating at your desk. Eating is something to be enjoyed, not rushed. When you rush your meal, you eat more and you aren't taking the time to enjoy any subtlety in the taste. This results, again, in overeating.

Surgeons are usually good at doing other surgeries as well...
