Let’s say someone ate poorly (high fat, junk food diet) and exercised very little for 5-10 years in early adulthood. But maintained a fairly balanced lifestyle and healthy weight afterwards. Would the body “recover” from the negative effects of being overweight or does the lifestyle change simply pause the negative effects from increasing?
In: Biology
Mostly the body will recover. If someone is extremely overweight/sedentary some diseases can start which are non-reversible, like CHF, fatty liver, and enlargement of the heart muscles. But those are extreme cases. Generally speaking clean living will get the body back to “normal” albeit slowly in some regards. It is markedly harder with age, though, and bad habits become harder and harder to break. Which is why it’s best to learn healthy habits early and make them lifelong.
