So I was recently diagnosed with breast cancer, and am desperately trying to change my diet. Since my cancer is estrogen based, A lot of people seem to swear if I going vegan makes all the difference. My problem is in less than a week I have a lost 4 pounds and gained 3% body fat from strictly eating vegetables and fruits. I only weigh 107 pounds and really can't afford to lose anymore weight. What do vegans eat to add calories and protein to their diets. I need to stay away from all animal products, and soy as much as I can. Also, I was going to buy Orgain organic plant based protein powder so I can get some protein in my diet. That would considered a processed food then wouldn't it? I'm supposed to stay away from processed foods also. Ugh! I'm at such a loss, I am beyond hungry and have no idea what I should or shouldn't eat.
