The Warrior Diet was introduced by a book published by Ori Hofmekler in 2The diet was designed to help people stop the dieting, weight loss, and regaining weight cycle. The plan involves undereating during the daytime and overeating at night. This is what warriors did in the ancient Roman and Spartan societies. But, this plan is contrary to many modern ideas about health and nutrition.
Overall, the diet proposes that you should focus on your instincts regarding eating. Don’t worry about types of calories or which foods have more or less nutrients. Eat like warriors in ancient times: they ate what they hunted at night and had little to eat during the day. You should fast in a controlled manner and exercise without eating much food before. The goal is to eat primarily during 1 meal per day, at night.
