Fasting is effective

It’s proven that this healthy lifestyle leads to fast weight loss. During fasting, as your glycogen depletes, your body switches to ketosis, which is referred to as the body's "burning" mode. This is an effective way to burn fat.


Fasting is safe.

It’s the most natural and safe way to lose weight.
Studies show that eating all the time makes your body unable to take a break from digesting.
When you fast, you just take a break from eating, it takes some of the load off your liver.



Record intermittent history every single day.
Achieve your successful healty diet!
