Going "keto" by eating in a high-fat, moderate-protein, and low-carb pattern enables you to break free from the disastrous effects of carbohydrate dependency. Instead, you'll reset your metabolism to promote metabolic flexibility -- where your body learns to burn fat instead of sugar for energy, even when you take a break from the plan. Many ketogenic programs require challenging restrictions and deprivation or offer misinformation, but Mark Sisson, publisher of the Mark's Daily Apple paleo blog, presents a two-step approach for going keto the right way. He first reveals the real secret to rapid and sustained weight loss, which is in becoming "fat-adapted" before entering full nutritional ketosis, a process that allows your body to learn to burn fat more efficiently. It takes as little as twenty-one days to reprogram your metabolism to burn fat for fuel by ditching processed grains, sugars, and refined vegetable oils in favor of nutrient-dense, high-fat, primal/paleo foods -- and you'll see immediate results. Next, you'll fine-tune with Intermittent Fasting and then foray into full ketogenic eating for a further weight-loss boost and improved health. With The Keto Reset Diet, you can eat to total satisfaction by enjoying rich, high-satiety foods, and even weather occasional slipups. You'll use keto as a lifelong tool to stay trim, healthy, energetic, and free from the disastrous health conditions caused by the typical American diet. With step-by-step guidance, daily meal plans, and a recipe section with more than 100 delicious keto-friendly recipes, this is the definitive guide to help the keto beginner or the experienced health enthusiast understand the what, why, and how to succeed with ketogenic eating.
