What is crash dieting and how could it affect my health?

Don’t crash diet if you want to lose weight and keep it off in the long term.

Crash dieting sound dramatic. And it can be; but not in a positive way. Many people embark on a harsh, low calorie diet to lose weight quickly. People who crash diet think that “less is more”. But if you diet too hard, too fast, your body will eventually fight back. You could end up in a worse position than when you started.

What defines a crash diet?

There’s no medical definition for a crash diet. But there are some red flags to look out for. A crash diet will expect you to slash your calories right from the start, often to below your BMR (the amount of calories your body needs to survive). Crash diets often make lofty promises about how much weight you’ll lose in a week (or fortnight). Statements like “lose half a stone in a week” or “lose 16lbs of fat in a month” are not uncommon.

Do crash diets actually work?

Going on a crash diet often delivers short-term results. By cutting your calories so low and making drastic changes to the type of food you eat, your body will shed weight. But there are lots of problems with this dramatic approach to losing weight.

 Why are they a bad idea?

Losing weight by making drastic changes to your normal diet is bad news for your body and mind. You will lose weight, but it won’t all be from unwanted body fat. You will also lose precious muscle tissue. Your metabolic rate will drop (making it harder to lose weight in future). And you risk severe food cravings and binges on a crash diet. The rebound effect from crash dieting can be severe. You could be left clueless about how to get back on track.
