How does intermittent fasting work

When we eat, the carbohydrates present in the food break down into glucose, which mixes with the blood and is used by our body in energy. And excess glucose is stored in other organs like the liver and tissues for later use, called glycogen and fats. That is why it is recommended not to eat excess food or sugary items.

But, fasting can convert glycogen back into glucose. And the fat may break down into fatty acids to convert itself to ketones and then to glucose. Therefore, you can lose weight by intermittent fasting.

Also, the insulin level increases when you eat food and decreases between the gap of another meal. So, if you eat food the whole day, your insulin level will remain high, desensitizing body tissues causing insulin sensitivity. So, you can try intermittent fasting, and if you are a beginner, begin with 5:2 intermittent fasting. Prefer exercising, working out or doing creative activities on a fasting day to stay more fit and healthy.
