I try to understand something about calories intake, and the difference it makes the way you spread them on a week. Those numbers are mostly to simplify the calculation. Lets say 2000 is the perfect number for calories intake for a person who trains. He doesn't loose, he doesn't gain weight. That would be 14000 calories a week. Lets say he tries 3 different ways to distribute those cal in a week: A: 2000 a day for 7 days. B: 3000 a day for 4 days, 2000 a day for the fifth day, and 0 for the last 2 days. (Saturday, Sunday) C: 3000 a day for 4 days, 2000 a day for 1 day, and 0 for 2 days, but this time no side by side (Thursday Saturday) As we said, with method A, at the end of the week he hasn't lost or gain weight... Will B and C give different results?
