1. Ketogenic diet
The ketogenic diet is a low-carbohydrate, high-fat eating plan that has been used to control seizures in some people with epilepsy. The diet excludes carbohydrate foods such as grains, dairy, legumes, most fruits and starchy vegetables.
Supporters claim that a ketogenic diet can help burn fat and lose weight efficiently, but evidence on its long-term effects is currently lacking. It may also be challenging to follow this diet as it can cause side effects such as brain fog, fatigue, irritability, headaches and constipation.
