I've always been curious about going on a ketogenic diet, but with all the new trends I don't know if it is worth it.
There is actually some evidence that adults with epilepsy may benefit from the diet. Also, I know several people who have lost weight with it.
What types of foods are you allowed to eat while on a keto diet?
You have to eat foods that are high in fat, and low in carbohydrates. And make sure you get adequate protein.
