How Fasting Affects the Body

Intermittent fasting (IF) has become a trend recently. The key is to deprive our bodies of food for a fixed number of hours. IF can succeed only when it is based on a proper understanding of how fasting affects the human body.

Is fasting really good for us?

As the human body engages in metabolic functions to generate the energy it needs, fight microbes, etc., it generates active oxygen as a necessary byproduct. Active oxygen is the cause of inflammations and aging. As we eat and digest food, our bodies engage in this metabolic process. Eating constantly means generating active oxygen regularly. Therefore, it is necessary to let our stomach rest and stop the production of active oxygen from time to time.

“Fasting burns the fat buildup.”

The human body uses glucose from carbohydrates as its primary source of energy. When this glucose stock is completely exhausted, the body turns to fat for energy. With this, fasting helps us deplete our glucose stock more quickly, thereby speeding up the burning of the fat in our bodies.

“Hunger slows down our biological clock.”

When the glucose stock in the human body is depleted, some of the cells stop growing and begin to “eat themselves” to generate a new source of energy. This autophagy starts with cells that are no longer necessary to the body, such as sick and aged cells. This process rejuvenates and strengthens the human body.

Four Rules of IF

1. Drink lots of water, and eliminate caloric intakes during fasting.

Fasting means eliminating caloric intakes. It can also lead to dehydration, so it is important to stay hydrated by drinking water.

2. Eat nutritious meals, and avoid compensatory eating.

When you eat after fasting, make sure to eat nutritious meals rich in proteins, vitamins, etc.; however, avoid compensatory eating. IF does not mean you can eat whatever and however much you want while not fasting. Repeating overeating and fasting is bad for health.

3. Do cardio exercises.

During fasting, the human body depletes glucose and begins to burn fat and proteins for energy, reducing the muscle mass. It is important to do some cardio and muscle-strengthening exercises to maintain the muscles.

4. Talk to a professional first.

IF is not the answer for everyone. Make sure you consult a medical professional about your health conditions before deciding whether to start IF. It is not recommended for young people who need nutrition to grow and develop and also for seniors prone to frailty.
