Highly recommended, although I think the "keto" diet is a bit of a misnomer, it doesnt have to do with eating specific foods per say, but allowing your body enough time to digest and use up energy consumed from foods and waiting 17 hours or so to eat so your body goes into ketosis. Althoguh this time may change from what you consume it isn't WHAT you are eating that makes a keto diet keto, but the fact your body goes into ketosis to use the naturally stored glucose in your liver and muslces!
