For a lot of people, the reason they feel hungry is because the way their brain works is that they feel better when they feel full and their life sucks for some reason, so they want to feel better. Hence overeating. It’s entirely a psychological issue for a person like this. Counting calories is not going to help them. In fact, them even being able to maintain a calorie counting regime is downstream of resolving their anxiety/stress/depression. In other words, diet and exercise are not the beginning in the causal chain required for them to lose weight.
And you’re getting absolutely no traction in this thread because you’re completely oblivious to this. Which is common for someone for whom diet and exercise is easy to control.
