And consult your doctor before starting, especially if you have any existing health conditions.

The ketogenic diet puts your body into ketosis " — a metabolic state where it burns fat for fuel instead of carbohydrates. When done correctly, keto can produce rapid weight loss, improved energy, and better blood sugar control. Here's everything you need to know to start keto the right way.

How the Keto Diet Works

On a standard diet, your body uses glucose (from carbs) as its primary fuel source. When you drastically reduce carbs (below 50g per day), your body runs out of glucose and switches to burning stored fat for energy. This metabolic state is called ketosis. Your liver converts fat into ketones, which become your brain's primary fuel source.
