If I may take some liberty, and speak only to those overweight folks who want to be thin, I suspect most of my readers have visited this site because they are overweight and further that they have previously tried various ways to lose weight, without success.
The reason? You are looking at weight from a physical rather than a mental mindset. You are fat not because this or that diet didn’t work. You are fat because your mind doesn’t work right. You have a mental disorder.
So read again Marcus Aurelius, elsewhere on this site. Read other books on the meaning of life and on stoicism. Read the essays of Montaigne and adopt his philosophy that you must first be true to yourself, that the opinion the masses may have of you is of no moment. Train your mind to accept hunger, even to relish it, for the rewards hunger brings are great.
