Because it is a cutting diet designed for another person.
Use the basis of the diet, tweak it to fit YOU. If that means eating more, then eat more. If it means eating different foods, then eat different foods.
EVERYONE has to take a base diet, and tweak it to fit their goals, their genetics, their life, their EVERYTHING. No one diet, one eating style, one choice of foods works for everyone.
Use the principles set forth to make it work for YOU. The base is the same - regardless. Eat clean, eat often. The details are individual.
