Look up intermittent fasting. (And I'm not talking about 'Yogi on top of a mountain' type fasting.) Helps kick in apoptosis (removal of malformed cells in the body, potential cancer, by your body's natural cleansing mechanism.) Eating several meals plus snack(s) a day keeps your body from entering this phase and doing it's natural job. It also keeps your blood sugar elevated and insulin pumping constantly to deal with the food you keep adding every few hours. Fasting helps control blood sugar and insulin release, if you 'honestly' do it right.
