Many doctors have given up on recommending lifestyle changes to patients because compliance is so poor. They see it as a waste of time and prefer to focus on interventions that seem more effective.

If you want to make lifestyle changes then it might be more useful to consult with a dietician, personal trainer, or therapist instead of a physician.

I believe many people don't follow those recommendations, because no one is told how. like lose weight and exercise - how exactly? There's a middle bit missing imho - an average joe's food and exercise centre if you will. personal trainers and nutritionists are next level in my experience, they're not really interested in telling average joe's walk a bit and do some exercises, same with nutrition - people need recipes that they can make easily, and healthy food they can buy when out easily. These things don't exist in my experience. The junk food industry is huge, as is the diet industry - saying do these easy things and you'll be sweet isn't really a money making proposition afaics.
