A crash diet will expect you to slash your calories right from the start, often to below your basal metabolic rate, or BMR the amount of calories your body needs to carry out its basic functions. Handpicked content: Your guide to basal metabolic rate BMR.

By cutting your calories so low and making drastic changes to the type of food you eat, your body will shed weight. Here's why you shouldn't go on a crash diet, and opt for safer weight-loss options instead. A better way to approach dieting is to eat nourishing foods high in protein and fibre to promote satiety fullness.

This means that when we eat less, our bodies slow down our metabolic rate in order to preserve energy. For our ancient ancestors, this was a survival tactic which helped their bodies prepare for a period of food scarcity.

A study found that very low calorie diets cause an initial rise in the amount of fat present in the heart. This can trigger complications in those with existing heart conditions — such as shortness of breath, palpitations and arrythmia.

The study followed 21 obese volunteers as they reduced their calorie intake to to calories daily for eight weeks. A balanced diet is one that includes a range of nutrients — including high-fibre foods, carbohydrates, protein, vitamins, minerals and healthy fats.

Your body needs balanced amounts of these to carry out its many functions, from powering your muscles to maintaining a strong heartbeat.

Fad diets such as the cabbage soup diet and the cayenne pepper cleanse are particularly problematic, as their highly restrictive nature make it very difficult for you to meet your nutritional needs. In a healthy, gradual weight-loss plan which includes exercise, the effect of losing muss mitigated as exercise offers protection against muscle loss.

Improving your diet reduces your risk of these problems, and can offer more energy, confidence and a boosted quality of life.

Your BMR is the amount of energy your body needs to carry out the most basic functions which keep you alive, such as the heartbeat, digestion and breathing.
