As most things about the human body, it actually is more complicated. Caloric restriction also causes biological responses in our bodies, influencing hormones such as ghrelin and leptin which physiologically alter hunger and satiety. Some people can even be resistant to leptin for example, meaning that they struggle with a lack of satiety. Our bodies have also been shown to reduce their energy requirements by about 200 calories per day when intake is restricted.
So even if we disregard the problems the claim it’s just a matter of willpower, there are other, biological things to consider.
All this to say, it is undoubtedly good to have more fiber, around 1.2-1.6g protein per kg of bodyweight, 120minutes of excercise a week and strength training, or just whatever we can implement into our routines.
Oh, and one more thing, fatness isn’t a ubiquitous measure of healthiness or virtue, and thinness isn’t either. We have to challenge our assumptions and biases, a lot of which come from our cultures and media.
I thought the same thing, and tried to find the 2 replies. In the grand scheme of things, it does not matter though, because all three of these ghouls would say whatever gets more attention because they are amorphous blobs of shite.
