Eat meat, avoid processed food, lift weights -> lean and muscular.

As I see it, you've just avoided 90% of the health problems that everyone else has.

It's just that simple.

That’s pretty much it. Barring chronic health conditions, you can be healthier than most people without all that much effort — and live longer, too.
