The Ultimate 800 Calorie Diet Plan:

Lose Weight in Just One Week

About the 800 calorie diet

This weight loss plan, also known as the fast 800-diet, is divided into two stages. 

Stage 1

The first stage, which aims to jump-start your metabolism and prepare your body for the overall process, entails eating 800 calories per day for at least two weeks.

Stage 2

In the second stage, you must switch to eating 800 calories twice a week. On the remaining five days, you will eat a Mediterranean-style diet with plenty of fresh fruits and vegetables.

Why is the 800 calorie diet divided into two stages?

The first stage focuses on activating your metabolism. The second stage ensures that your body enters ketosis.

Benefits of the fast-800 diet

The 800 calorie diet has numerous advantages ranging from battling cancer and dementia to fighting diabetes.

Helps to fight diabetes

According to research, the fast 800-diet, which involves consuming fewer calories than usual, can be used to combat diabetes by lowering blood sugar levels.

Can lower the risk of dementia

The eating plan that you follow in stage 2 lowers your risk of dementia because it includes anti-inflammatory foods that are high in beneficial minerals and vitamins.

Can reduce the risk of cancer

Eating more fiber and avoiding red meat and processed foods, both of which are compatible with the fast-800 diet, can help prevent cancer.
