Why YSK: many countries have issues with weight, such as mine with 74% of US adults being overweight or obese. The global weight loss industry is over $200 billion yearly, with many influencers, pills, and surgeries promising quick results with little effort. These often come with side effects, or don’t work long term.
Studies suggest filling yourself with foods low in caloric density and high in fiber, like fruits and vegetables, can help reach and maintain a healthy weight. It’s good to have these foods available in our living spaces to make the choice easy. Your taste buds will likely adapt to love them if you’re not there yet.
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.
No. If you stop losing weight on a caloric deficit, you miscalculated the deficit. It’s a thermodynamic certainty. When people hit a long term plateau on a CICO diet, it’s because they either failed to adjust their total daily calorie expenditures for their new weight, or most likely they’re cheating on their calorie counts.
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.
Neither of you have cited any sources, this discussion ain’t going anywhere and you should not be listened to
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.
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:
[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.
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 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.
