The benefits of fasting 

There are many benefits to fasting. These benefits include weight loss, detoxification, and better mental clarity.

1-Weight Loss 

When you fast, your body is not getting any food to compensate. As a result, your body burns the stored fat in your body. That leads to weight loss.

Fasting can help you lose weight because it allows you to burn more calories. However, when you fast, your body goes into survival mode and starts to burn stored fat for energy. That can lead to significant weight loss over time.


Fasting also helps detoxify your body by removing toxins from your system. For example, when you stop eating, your body has a chance to cleanse itself of toxins that have built up over time. That can help improve your overall health and well-being.


Fasting also boosts your metabolism, helping you burn more calories throughout the day.

4-Reduced Hunger 

One of the best things about fasting is that it reduces hunger cravings, making it easier to stick to your diet plan.

5-Lower Blood Sugar Levels 

Fasting can help lower blood sugar levels, making it an excellent choice for people with diabetes or prediabetes.

Types of fasting

There are many types of fasting, but they can generally be divided into two categories: total fasting and partial fasting.
