It varies. We are all genetically unique so there is no single diet perfect for everyone. But most people will lose weight by minimizing high-glycemic foods like grains, sugar & potatoes (see http://www. Glycemicindex. Com/) & avoiding fried/fatty foods. Emphasize vegetables & fruits, beans, organically raised eggs & meats & wild seafood. Dairy, nuts seeds & whole grains can be eaten in moderation.
Everything moderate. Eating everything in moderation is your best bet. Common sense rules the day, fatty fast food obviously should be avoided if possible. Consider adding exercise to your regimen and you have a winning formula.
