Both keto diets and the Atkins diet focus on a reduction of carbohydrates in order to burn fat, but the keto diet allows dieters to continue to eat meat, in particular encouraging the consumption of red meat. Keto diets thus make use of a wider range of protein sources than the Atkins diet.
Keto dieting may well look very similar to the foods you’re already eating. In fact, the keto diet is well known for letting dieters continue to eat many of the foods they love. Love cheeseburgers? Keto has you covered: cheese and ground beef are both encouraged in the keto diet. All you have to do is switch to a carb-free “bun” (lettuce is a popular choice) and you can have as many burgers as you want.
