Someone explain it to me again... pleez. Does your stomach become that sensitive to food when you are in such a caloric deficit? Is it the extreme stress levels? Is it the dope? Is it eating foods you arent accustomed to eating regularly? Travelling?
All of the above?
I was told by my doctor that athletes and bbing competitors tend to get more colds, and stomach issues due to their immune system being down or compromised because of the extreme conditioning or pushing their bodies to the max. That is why many Olympic athletes get sick.
So, you take a bbing competitor who is at single digit bodyfat, his/her immune system is very compromised
its gonna eff with your stomach.
