Recently, Intermittent fasting has become the hottest eating pattern trend. Intermittent fasting involves cycling between periods of fasting and eating. It could offer significant health benefits like weight loss, the reversal of type 2 diabetes if you do intermittent fasting properly. Here is the ultimate guide to do intermittent fasting for beginners.

What is intermittent fasting?

Intermittent fasting is not a diet. It is an eating pattern that cycles between periods of fasting and eating. You schedule your meals when you eat. But it does not change what you eat.

There are many ways to do intermittent fasting that all are based on setting up regular periods to eat and fast. It works by prolonging the fasting period when your body has burned through the calories consumed during your last meal and begins breaking down fat and burning calories.

Five stages of intermittent fasting

Intermittent fasting can be divided into 5 stages.

Stage 1 – Ketosis and heavy ketosis: You have entered the metabolic state called “ketosis” by 12 hours that your body starts to break down and burn fat. And, you have turned on the fat-burning mode called “heavy ketosis” by 18 hours.

Stage 2 – Autophagy: Your body cells are recycling old components and breaking down misfolded proteins within 24 hours, which is called “autophagy”.

Stage 3 – Growth hormone: Your growth hormone level is up to five times when you started intermittent fasting by 48 hours without calories or with very few calories.

Stage 4 – Insulin reduction: Your insulin has decreased to the lowest level point and you are becoming insulin-sensitive by 54 hours.

Stage 5 – Immune cell rejuvenation: Your body is breaking down old immune cells and generating new ones by 72 hours.

Intermittent fasting could help you lose weight and belly fat without restricting the intake of calories. It could also lower blood sugar, reduce insulin resistance, decrease bad LDL cholesterol that protects against type 2 diabetes, and prevent heart disease. Some research results indicated that intermittent fasting could reduce inflammation and prevent chronic diseases.

Intermittent fasting is not risk-free. People who have existing medical conditions should seek medical consultation with doctors before getting into intermittent fasting. The common side effect of intermittent fasting is hunger and feeling tired. You might overeat and get dehydrated during eating or fasting cycles.

DISCLAIMER: Intermittent fasting might have potential side effects on certain people especially those who have medical conditions. Please seek medical consultation with doctors before starting intermittent fasting.
