What is the Ketogenic Diet?
The ketogenic or "keto" diet is a very low-carbohydrate, high-fat diet that shares similarities to low-carb diets like the Atkins diet. The keto diet causes the body to enter a state of ketosis, which means the body starts breaking down fat for energy instead of carbohydrates.
On the keto diet, about 75% of daily calories come from fat, 15-20% from protein, and 5-10% from carbohydrates. Restricting carb intake causes the body to deplete its glucose stores, so the liver starts converting fat into ketone bodies and fatty acids for energy.
Some benefits of following a ketogenic diet include:
- Weight loss
- Reduced hunger and appetite
- Lowered blood sugar and insulin levels
- Improvements in heart disease risk factors

Frequently Asked Questions

Can you eat fruit on the keto diet?
You can eat certain fruits on keto sparingly, including berries like strawberries, blueberries and raspberries. Be careful of carb counts though - only about 1/2 cup fresh fruit per day.
What vegetables should you not eat on keto?
Avoid starchy vegetables like potatoes, sweet potatoes, corn, peas, butternut squash and most root vegetables since they are too high in carbs for keto.
