Keto: How it works

How it Works

When your metabolism starts to burn fat for fuel, instead of carbs and sugar, your body loses weight more efficiently.

What You'll Eat

Classic keto diets include very high levels of fat (75-90% of calories), relatively low levelos of protein (5-20% of calories) and extremely low levels of carbohydrates (less than 5% of calories) and may also be calorie restricted.*
