Intermittent fasting is not a type of diet, but an eating schedule. Your body is always in one of two states: fed or fasted. In the fed state (anytime your body is digesting food), your body’s insulin levels make burning fat a challenge. However, in the fasted state (8-12 hours after your body finishes digesting), your insulin levels are lower and better able to reach into your fat stores. People rarely go into a fasted state throughout the day. In fact, the traditional theory of several small meals per day keeps us from ever reaching the fasted state. In addition, that type of eating schedule regularly spikes our insulin levels which also hinders fat loss. So, while eating several small meals per day can lead to weight loss (calorie deficits always do), you will likely be losing both muscle and fat. When you lose calorie burning muscle, you lower your metabolic rate and make it harder for your body to burn fat. You also might become frustrated because you never feel toned and fit, even though you are working out and eating clean.
SO, YOU DON'T EAT?
Not exactly. The FASTer Way to Fat Loss program has eating windows, combined with high and low carb days (also known as carb cycling). You will actually find that in this program you eat all of the time! The difference is that you will have a shorter eating window throughout the day allowing your body to enter into the fasted state.
What Will It Do To My Metabolism?
If you’ve ever heard that intermittent fasting will cause your metabolic rate to plummet, this is simply not true! In fact, studies show that intermittent fasting can actually raise the metabolic rate anywhere from 3.6–14%!
What’s So Great About It?
It turns your body into a fat burner. Intermittent fasting allows time for the body to utilize fat as its main source of energy, which means you not only lose weight, but you’ll see an improvement in your overall body composition. Intermittent fasting allows you to maintain muscle mass, which speeds up your metabolic rate while helping you shed fat.
Daily periods of fasting also changes your body on a cellular level. This is when natural detoxing takes place through a process called autophagy. Your cells get a chance to remove waste and repair! In addition, it helps regulate hormones like insulin and HGH to make the fat stores in your body more accessible.
Potential Additional Benefits of Intermittent Fasting Include:
better sleep and more energy
greater mental clarity and increased neuron development in the brain
improved hormone profile
increased life expectancy
maintenance of skeletal muscle mass
decreased blood glucose levels
decreased insulin levels
increased insulin sensitivity
slowing of brain aging biomarkers
Your body may take a short amount of time to adjust (after all, it is used to eating from morning until night), but you won’t be hungry because you’ll consume the proper amount of food during your eating window.
