Essentially, the bodies starvation response kicks in (like a crash diet ), in order to conserve energy. In the first 24 hours of the fast your body will utilize glycogen (easily-accessible storage form of glucose, stored in small quantities in the liver and muscles) to provide energy for your various body processes to keep functioning. Once your carbohydrate reserves have been exhausted, your body utilizes stored fats. After several days of fasting, your body begins to break down protein, which is converted into glucose. Much of our muscle mass is protein and thus muscle tissue is often lost.
You suggest exercising as late into the fast as possible. You also suggest that a post-workout meal will likely include good tier 2 carbs. But the book describes your first meal in various places as a low-carb and low-calorie, light foods, and raw foods, with the real feast coming later for dinner. You also suggest exercise most if not all days of the week, so I don’t think my confusion is related to workout days vs non-workout days.
When keep consuming unhealthy food our body collect toxins that can't go our easily. Detox teas contain specific blends of natural ingredients which flush these toxins and chemicals we are consuming out of our vital organs. Those herbs are extremely effective for reducing cholesterol, body fat, improve digestive system and help our body losing weight.
And Ian K. Smith, M.D. agrees. Dr. Ian is a Harvard graduate, founder of the SHRED Lifestyle, and the author several best-selling diet books. He explains that the liver, kidney, lungs, skin, and gastrointestinal system remove toxins that accumulate in the body. But following a detox diet full of natural foods can enhance the body's ability to cleanse. He adds, however, that dieters should make no assumptions about health when choosing a detox diet. "Detoxes have gotten very trendy, and many of them are unhealthy and quite dangerous."
