I have recently returned from a trip to Taiwan where everyone seemed obsessed by the Keto Diet. For those not familiar, this diet, favoured by celebrities such as Kim Kardashian and Megan Fox, is a high-fat, very low-carb regime.
The idea is that eating minimal amounts of carbs will force your body to burn fat instead by turning fatty acids in your blood into ketone bodies.
The body (and brain) then uses these as fuel instead of glucose from carbohydrates.
