Informative but the preachy, shaming tone takes away from it.

It's interesting and informative. I wish it wasn't so preachy and shaming. There are two huge points glossed over in this. The first is that he got fat because of his psychological disposition rooted in the death of his younger brother then shame later at being "fat" in a fat shaming greater society. The second is that the film emphasizes exercise in weight loss despite having clearly shown that his excessive eating habits were the primary physiological contributor to his weight. People don't need to actually do workouts just to lose weight. Managing diet is enough. Exercise is great for conditioning but not as the primary tool of weight loss. It makes people think that intense workouts are the only way to lose weight and they're not. It's a false barrier. So... the shaming, blaming, preachy tone negates the useful info and overarching message. He even acknowledged the psychological contributor to his being overweight earlier only to self-blame further into the film... So too does the emphasis on exercise over diet weaken the effectiveness of the message. I'll add that taking a more patient, gradual approach would have been wise as well. He'll be more likely to gain it back with drastic changes in diet and exercise leading to drastic changes in weight in a short time. Taking it slowly reduces such chances.
