Let’s take a closer look.

What is the Ketogenic (Keto) Diet, and is it right for you?

The Keto Diet is an ultra-low carb diet, with a mere 5% – 10% of dietary intake comes from carbs. Unlike other low carb plans, Keto is also low protein, as only 20% – 25% of calories come from protein. The bulk of energy, 70% - 75%, comes from fat. Following this plan forces the body into a state of ketosis. Ketosis occurs when people eat a low- or no-carb diet and molecules called ketones build up in their bloodstream. Low carbohydrate levels cause blood sugar levels to drop and the body begins breaking down fat to use as energy, rather than carbs. ketogenic diet graph Now that you know more about the Keto Diet, we will break down the pros and cons and will provide some tips to make the Keto Diet work for you.

More energy
