Put simply, low carb. Low enough that your body uses lipolysis/ketosis to generate ketones for energy rather than glucose from carbs, so you burn fat for energy. Typically under 50g carbs/day will get you into ketosis, but most commonly under 30 is your safest bet. So, fatty meat, nuts, cheeses, little dairy, veggies, and minimal berries. High fat diet.
see: Atkins or South Beach diet. They're both ketogenic diets. LINK
Lipolysis is the breakdown of lipids and involves hydrolysis of triglycerides into free fatty acids, followed by degradation into acetyl units by beta oxidation. It produces ketones, which when produced in large quantities are described as causing ketosis. These can then be used by the body for energy. Lipolysis testing strips are used to detect ketosis, primarily in diabetic ketoacidosis.
