"Doctors won't mention that losing weight and exercising more will make you healthier" is quite a take.
I've heard exactly the opposite from any number of people: that if you're overweight at all, many doctors will tell "lose weight and exercise" and then usher you out the door, rather than pay attention to the specifics of your medical problems - sometimes missing serious issues as a result.
When they have to turn patients over at the rate of 10 per hour due to the policy of the private equity group that owns their practice, they will be inclined to offer blanket advice that, while actually good and applicable for 80% of people, will tend to miss the edge cases.
