While it might be tempting to slash your calorie intake considerably in an effort to lose weight fast, you shouldn’t aim to shift more than 2lb a week – although you may lose slightly more than this when you first start slimming as your body gets rid of water as well as fat. In the long term though, a weight loss of more than 2lb a week means you’ll have to cut calories excessively – and ultimately, this will make it even harder to shift those pounds. Effectively, very low calorie intakes simply push the body into ‘starvation mode’ so that it becomes super efficient at making the most of the calories it actually gets from food and drink. It does this by protecting its fat stores and instead using lean tissue or muscle to provide it with some of the calories it needs to keep functioning. This leads to a loss of muscle, which in turn lowers metabolism so that the body needs fewer calories to keep ticking over and weight loss slows down – not ideal if you want to shift unwanted pounds!
