2.2 Key Metabolic Changes During Fasting
When you start practicing fasting, there are several key metabolic changes occur in the body. Your body starts using Ketones produced from stored fat as a primary fuel for energy instead of glucose. This metabolic change in the body results in fast fat-burning and weight loss, insulin sensitivity improvement, and reduces inflammation.
Fasting also helps in boosting muscle growth and muscle repair due to an increase in human growth hormone (HGH) levels which also improves bone density and overall health.
2.3 The Impact on Insulin and Blood Sugar Levels
There is no doubt intermittent fasting helps in regulating insulin levels and improves insulin sensitivity. Improvement in insulin sensitivity has other health benefits as it helps in stabilizing blood sugar levels, which in return reduces the risk of type 2 diabetes and helps in preventing energy crashes.
2.4 Hormonal Effects and Cellular Repair
Intermittent fasting has positive hormonal effects such as it helps in the increase in production of norepinephrine. Norepinephrine is a hormone that increases focus and helps in boosting alertness.
Also, Intermittent fasting helps in improving brain function, development, and growth of neurons by releasing brain-derived neurotrophic factor (BDNF)
During fasting body starts the cellular repair process, in which old cells are recycled and damaged cells are removed from the blood.
Section 3: Benefits of 16:8 Intermittent Fasting
3.1 Weight Management and Fat Loss
One of the major reasons people try intermittent fasting is to lose weight and reduce belly fat. In intermittent fasting, the eating window is restricted which allows one to consume fewer calories and promotes weight reduction.

3.2 Enhanced Energy Levels and Mental Clarity
Those individuals who practice 16:8 intermittent fasting claims to have increased energy levels and help in improving mental health. While using stored energy fat as a fuel your energy levels are more stable and helps in preventing energy crashes and increase focus and productivity.
Also, the release of the hormone “norepinephrine” during fasting enhances alertness and cognitive function.
3.3 Improved Insulin Sensitivity and Blood Sugar Control
The 16:8 intermittent fasting improves insulin sensitivity and helps to maintain blood glucose levels it acts by reducing insulin resistance and the help body’s ability to make effective use of insulin in reducing risk for type 2 diabetes mellitus and other insulin-related metabolic disease
