I’ve read various things about people who stop smoking can recover lung function reverse the damage as if they had never smoked etc. Although I find it hard to believe.
We know that being overweight is unhealthy: a strain on joints, on the heart etc
There is a possibility Type 2 diabetes can improve or even go into remission with weight loss
But if someone’s overweight or obese and they lose weight are there any long term effects? Stretch marks won’t disappear but what else has gone wrong forever?
