Intermittent fasting (IF), a regime with simple and dynamic weight management and health implications, has been discussed widely lately. IF differs from common diets primarily in that it is based on when food is consumed, not what food is consumed. Substantial scientific findings say that fasting can assist in the body’s self-repair, enhance metabolism, and promote multiple aspects of health.
This blog discusses the science behind intermittent fasting, the advantages of different fasting methods, and methods for ensuring a successful fasting routine.
What Is Intermittent Fasting?
Intermittent fasting is an eating pattern that cycles between periods of fasting and eating. Rather than focusing on particular foods, IF is time-centric eating. The idea is to give the system some time off from digestion and into fat-burning mode.
There are several ways to conduct intermittent fasting, but the main idea is lengthy periods of not consuming.
How Intermittent Fasting Works
When one eats, one temporarily breaks glucose from food to be used as energy; but as the body begins to fast due to not taking in food, it gives way for fat-burning. This process is known as ketosis and is great for fat loss.
By fasting, there is an initiation of autophagy, where cells begin eliminating damaged components and regenerating. This helps maintain health benefits and probably longevity.
