How Does Intermittent Fasting Work?

Intermittent fasting is an eating pattern that cycles between periods of fasting and eating. It doesn’t specify which foods to eat, but rather when to eat them.

During the fasting period, your body uses up its stored glucose (glycogen) and starts using fat stores for energy. This leads to increased fat burning, which can help you lose weight and fat over time.1

Intermittent fasting can also help improve insulin sensitivity, which means your cells can use glucose from the bloodstream more efficiently. This can reduce the risk of type 2 diabetes.2

Additionally, fasting triggers cellular repair processes, which promote overall cellular health by removing dysfunctional components and recycling them for energy.3

Intermittent fasting can offer several health benefits. However, it’s important to listen to your body, stay hydrated during fasting periods and maintain a balanced diet when eating.
