Is anybody one?
I played sports in college and I guess my body was more resilient then. I still want to be vegetarian now, but I need to be more conscious. I am 28 and have been generally meat-free for almost 14 years. I think I over-did it this past week or so, either too much exercise or not enough food or not enough of the right kind of food (maybe not enough sleep too). So I have been taking it a bit easier in terms of exercise until my energy returns. Today is a bit better!
Eat lots of eggs, cheese, beans/legumes, whole grains, fresh produce, some protein supplement like boca burger or whey protein in smoothies. Things I try to pay attention to:
It doesn't seem like there is a lot of overlap. My vegetarian/vegan friends tend to be pretty scrawny, not into sports beside maybe riding bicycles or yoga. My athlete friends love to eat steak and things like that.
