If you're getting ill, then you're (probably) missing something in your diet.
After working out hard enough for a few months, I used to get an injury (muscle strains)... then take the rest of the season off to let it heal. It would happen every time I tried it.
At first I tried reducing my exercise... that worked.
Then I started paying more attention to my diet. Turns out, I would often only eat 45-60g of protein a day (not a huge fan of meat).
Fixed that.. now I can exercise hard every single day without any injuries.
My experience was similar. When I started Crossfit I was following my small portion eating habits and didn't really focus on getting enough protein, fat, or carbs (my thinking at the time was carbs and fat were bad, I had no distinction about WHICH ones were bad).
There was a point where I was complaining about feeling tired all the time and my coach asked me what my diet was like. I told him. He scolded me.
Ever since then I've noticed HOW MUCH diet truly affects my athletic performance and my recovery.
