I think weight loss is more than just calories in/out. Maybe our body reacts to adapt to situations and tried to change the body shape to make it easier for itself. So I think healthy habits are more important and can depend on genetic history too.

I think emotions are a huge part of weight gain and loss and yet most Western medicine seems to almost completely ignore the impact of emotions on the body. Try eating a lot of food when sad—it's hard to take even a bite. Yet it's hard to even realize just how much one is eating when anxious.

I also imagine the emotions impact digestion and storage of fats and a lot more, basically adapting our bodies to our perceived environments, so it kinda baffles me that we don't study the emotional impact more.

Yes, I agree. I feel we are definitely missing out.

A clear example is something like cortisol. It damages your body to give you a short term advantage to survive a situation.

Being under stress might make you burn lots of calories, but stress ends up being weight gain in the long term because the body tells you to save up more energy for next time.
