Very solid argumentation…

It is not. I am not saying people should not eat healthy or should not try to lose weight. I am just saying that pushing the oversimplification that for everyone it is just calories in vs calories out and that it is only about willpower is not correct. People should get the right help with losing weight and the factors that cause the weight gain or makes people not losing the weight should be addressed.

There is lots of scientific work on this. I copied some links from another comment I made.

For example, this is an article in Journal of Obesity. It discusses the role of willpower and provides an overview of some of the research on other factors that affect whether people lose weight, such as metabolic compensation.

This is another interesting paper in the Irish Journal of Medical Science on patient’s view on obesity as a disease. I think the conclusion of this study aligns well with some of my claims:

The presence of beliefs and perceptions to support the narrative that obesity is a choice, that choosing to eat less and move more effectively treats the disease and willpower is a principle determinant of weight loss maintenance may negatively impact long-term treatment. A belief that obesity is a choice will see prevention and treatment strategies continually focus on education regarding eating less and moving more, which may be suboptimal. Therefore, the narrative must change and align with the science regarding the biology of obesity as a disease.

[This] (https://www.sciencedirect.com/science/article/abs/pii/S0953620521000029) paper on weight regain also claims that it is not just about compliance with a diet, but that, amongst others, metabolic adaptation and changed appetite play an important role as well.

If you disagree, please provide some substantiation. I would be interested in reading it.

Thanks! I think you are describing what a lot of people experience. Weight loss is highly complex and by oversimplifying it, lots of people do not get the help they need and are made to feel bad about themselves.

There is actually quite some scientific work supporting what I am saying. For example, this is an article in Journal of Obesity. It discusses the role of willpower and provides an overview of some of the research on other factors that affect whether people lose weight, such as metabolic compensation.

I am personally quite interested in work on obesity due to eating disorders. The reason for this is that I suffered from an eating disorder causing obesity for most of my life (fortunately, I do not have the disorder anymore). The constant pressure to just eat less and getting blamed if you fail, severely increased my eating disorder and I saw the same thing happen to others with similar issues. I know that this is anecdotal and not everyone that is obese has an eating disorder and not everyone with an eating disorder is the same. However, there is some limited evidence that weight neutral treatment of binge eating disorder has better outcomes. This and treatment for my CPTSD is exactly what worked for me.

I think for most people it is not the best advice. In most cases, there are many other factors at play than just willpower and “calories in vs calories out”. Obesity should be viewed and treated more like a disease, because it is. If you are interested, I can link you some interesting papers on this.

My experience is that if you spend time on providing sources, people usually are not interested in them and will not change their mind anyway. So I do not feel like it is worth the effort in every discussion. However, if you are interested in the work on this topic that substantiate my claims, then I am very glad to provide some links to some interesting articles.

In conclusion many people with obesity who agree obesity is a disease appear to have an imperfect understanding of the causes and treatment options.

I hope that this provides you with enough evidence to at least take the things I was saying into consideration. Please let me know if you find this useful. I have a lot more to share if you are interested.

Like I said, that is an oversimplification. There are many other factors that play a role, like the body working against the weight loss and lowering metabolism and increasing appetite, as I already discussed. There are also psychological factors and environmental factors that can have a big impact on weight loss.

Just ignoring those makes losing weight more difficult and means you have to do it entirely based on willpower. If you are one of those people for which these other factors play a big role it becomes very difficult to keep the weight off in the long term just based on willpower. This can be the case, for example, if you have an eating disorder, very high stress, untreated medical conditions (e.g. hypothyroidism), not enough money to buy healthy food, problems with the body signaling hunger or fullness, unsolved emotional issues, and so on.

Of course there are some people who just eat too much and who can just lose the weight easily by eating less. However, especially for people who are very overweight, these factors will play a role. They hear they should just eat less all the time and if they fail they are made to feel like a failure themselves and as if they have a lack of willpower. This is not the case. For them losing the weight is more difficult and the underlying issues should be addressed. You cannot just generalise like that and apply what works for you to everyone else.

Edit: please find sources for my claims in my comment below.

Thanks for saying this. I think the idea that it is just willpower causes so much unnecessary suffering. As someone suffering from an eating disorder and thyroid disease, I was getting a bit down reading all the “it’s just calories in vs calories out” remarks. It is so much more complicated than that.

It is not as simple as just calories in vs calories out. Your body has a setting point for what weight it thinks it should be. Once you are overweight, your setting point will be higher and your body wants to get back to that higher weight. It will start working actively against you. This might mean your appetite will increase and your metabolism will slow down. I think that is what you are describing here.

Trying to push yourself to lose more weight despite your body working against you can cause rebound weight gain if you are not able to keep the diet (which might become increasingly difficult due to increasing appetite). The most important thing is to keep a healthy diet that does not reduce your quality of life too much and is doable on the long term, I think. If you are struggling everyday, then it might be better to eat a little bit more and stay on a higher weight a bit longer to ensure that you will maintain the weight loss.

Maybe this is already what you meant. But the phrase “calories in vs calories out” and stating that nothing else matters made me want to respond. I think it is a popular oversimplification that causes a lot of unnecessary suffering for people trying to lose weight.

Eating fruits and vegetables might definitely help and it is in any case very healthy! However, people should not always expect to lose more than 10% of their weight in the long term (over years). This 10% can already provide great benefits for your health, so definitely try to lose that weight if you are overweight.

Often it is said that it is just calories in vs calories out. This is only true up until a certain point. For many people, after losing about 10% of their weight, their body starts to work against more weight loss. Their metabolism starts to slow down and their appetite will increase, making it more difficult to lose weight. It might make it almost impossible to keep on a diet and it might even cause people to gain more weight back than they lost.

The theory behind this is that your body has a set point or settling point for what it thinks your weight should be. When you are overweight, the set point changes to a higher weight. When you lose weight, your body wants to get back to this higher set point. The set point can be changed to a lower weight, but that might take years and years. There also is some limited evidence that building more muscles might help somewhat.

I think it is important to add this to the discussion, as often there is the idea that weight loss is just based on self-control and limiting calorie-intake. While this might play a role, the idea that these are the only factors that determine your weight causes a lot of suffering for people. It might also cause more weight gain in the long term.

So, try to lose about 10% of your weight and if you feel like you are struggling after that, go to a specialised doctor who can help you with losing more weight (doctors without this specialisation are often clueless about weight loss in my experience). In addition, a psychologist might be able to help if your are overeating due to an eating disorder.
