Please help. I am doing Whole30 with my girl friend and having a good bit of trouble with my energy. I am 33 years old, six foot three inches and weigh about 195 to 200, ex college tennis player. I play tennis at least five days a week and do high intensity training at least five days a week as well. At one point during high school and college I was on a 6,000 cal diet, basically just eating as much as possible. What would you suggest with me always being hungry and searching for sources of energy? Thanks so much for your help!
