'Flip the metabolic switch': Dr Michael Mosley shares how to be a 'fat burning machine'

He continued: “The thing is your body wants to use the sugar first, because sugar is like money in your pocket, whereas fat is more like money in the bank – you’re storing it up for a rainy day when you don’t have access to food.”

What Dr Michael suggested is that slimmers start burning their stored fat, but to do this they first need to “deplete” their sugar.

By cutting calories to just 800 per day and reducing carbohydrates to very little, the body can start burning fat, meaning slimmers can achieve rapid weight loss.

Talking about dieters, he explained: “They will have run through their sugar supply and but the body would have flipped over into major fat burning.
