Yeah, most do suffer that for sure. But food intake is a bigger cause of health issues than people think. Everything down to your gut biome getting out of whack which can cause mental health issues as well (ask me how I know). It's all related. Exercising on bad fuel is not gonna help as much as you'd think.that's really all i'm saying. but also that generally it takes half a life-time to bugger your body with meat. just getting old and not moving as much is a WAY bigger problem for most of us.
I work out and exercise 4-5x a week pretty intensely, but still struggled with weight and other such things until I figured my food intake out.
