“Fasting gets more manageable over time as your body adapts to fueling itself with body fat rather than food.”

“Fat adaption is a process that happens after at least four weeks of ketosis. It’s the end of your period of transition into a low-carb diet. During fat adaption, your body is fully acclimated to burning only fat. You no longer crave carbs, and you tend to get fuller faster and stay that way longer. When you eat carbs, they don’t spike your blood sugar the way they used to, and blood sugar returns to a normal state more quickly. Your body may even become fat adapted without your even knowing it.”

“Fasting induces autophagy—a cellular process that helps the body clear out old or damaged cell parts—”

“If you extract breast cancer cells from tissue, it’s quite simple to grow them in a lab. If you add glucose, epidermal growth factor (EGF), and insulin, they multiply rapidly. If you then take away the insulin, they die. Let me repeat that: breast cancer cells proliferate with high levels of insulin and die without it. What lowers insulin levels? Fasting.”

“since the advent of the Dietary Guidelines for Americans in 1977, consumption data from the United States Department of Agriculture shows that Americans have been doing exactly what they have been told to. Americans have consumed less meat and dairy and replaced their animal fats with vegetable oils. They’ve eaten more grains, fruits, and vegetables. And what has happened? A tsunami of obesity the likes of which the world has never seen.”

“spoke to Jason and immediately started fasting and applying his principles of good nutrition, eating a variety of low-carb, healthy-fat, whole foods. Within weeks, I realized that, for my whole life, just about everything I’d learned about nutrition was wrong. It’s been eight years since I began following Dr. Fung’s recommendations, and I’ve maintained an eighty-six-pound weight loss. I have completely reversed my type 2 diabetes, fatty liver, and PCOS.”

“Supplements may hinder autophagy. When fasting for metabolic reasons (meaning insulin resistance–related conditions such as type 2 diabetes, obesity, PCOS, and nonalcoholic fatty liver disease), the effectiveness of supplements is questionable. Most vitamins are fat soluble, but if you’re not taking in fat they won’t be as effective. Probiotics are fine to continue taking while fasting.”

“HGH secretions go way up during fasting. In fact, according to a 1988 study, a two-day fast can help you produce five times as much HGH! This is greatly beneficial for men and women because strong, lean, sturdy bodies are better for health than leaner, weaker muscles and skeletal frames.”

“When I started fasting, I consciously and deliberately had to think of food as energy and nothing more, divorcing it from the more complicated places it had always stood for in my mind. I also had to tell myself—repeatedly—that I already had plenty of energy stored as fat, and that fasting would help me burn it.”

“It’s calorie-restriction diets that cause your metabolism to slow down to a crawl. Fasting does just the opposite. The hormone noradrenaline, which is produced during a period of fasting, boosts metabolic rates. As you fast more and regularly over time, metabolic rates go up, and more weight loss is achieved.”

“Type 2 diabetes is essentially a disease of too much sugar and too much insulin. What decreases sugar and insulin? Fasting. When your insulin is in check, your blood sugar stays in check, your weight stabilizes or decreases, and your risk of developing any number of chronic health conditions goes down.”

“Now I understand that my body can either be focused on storing energy or burning energy. But not both at the same time. When I eat often, my body becomes busy packing away energy as fat. When I eat less often, my body has more time to burn energy—and fat. Fasting allows my body to focus its efforts on using energy instead of storing energy. I still have warehoused energy in my body in the form of excess fat. My metabolic and digestive systems are completely capable of using that fat as energy—but not unless I give them the opportunity by not eating for a period of time.”
