Keto Diet
Very low carbohydrate, high fat eating that shifts the body into ketosis.
The ketogenic diet keeps net carbohydrates around 20-30 g per day, which pushes the body to produce ketones from fat. Many people find it reduces appetite.
Fat loss on keto still comes from a calorie deficit. High-intensity training performance may drop, especially in the first weeks. People with diabetes, kidney issues or who take medication should talk to a doctor before starting.
