When it comes to calories, cutting back by more than 500 kcals per day puts you at serious risk of “under fuelling”, which leads to a slowdown in your metabolism and encourages fat storage and muscle loss.
Unless you are on a crash diet and are prepared to accept the compromise to your metabolism, make small changes to your diet that will lead to sustainable changes in your body composition.
The theory: Cut 1000 kcals a day / Lose 2.2 lbs (1 kg ) a week / Lose 2 stone in 3 months / Live happily ever after.
The practice: Cut 1000 kcals a day / Los 2.2 lbs (1 kg) a week / Lose 2 stone in 3 months / Gain 2 stone and more in next 3-12 months / Start again.
