How much weight can you lose on keto?

It is possible to lose 0.5 lbs (0.227 kg) per day while fasting, which amounts to 3.5 lbs (1.58 kg) per week in a best-case scenario. Initially, you might lose 7 to 15 lbs in the first week, mostly water weight from glycogen. Glycogen, stored with 3 to 3.8 grams of water per gram, is quickly used up during fasting, causing significant water loss.

Factors affecting weight loss during fasting include:

- Age

- Activity level

- Gender

- Metabolism

- Overall health

- Diet

- Stress level
