A body to kill for, but are the diets that create them, killing them?

Low-calorie - This generally involves eating very little breakfast, not too much for lunch and tiny snacks throughtout the day, the only meal eaten is dinner. As well dropping a dress size you'll also find you have no energy and trouble concentrating if you use this diet. A woman needs about 2000 calories a day (men 3000) this is roughly halfed when on this diet. Healthy snack throught the day is a good idea though; try bananas and raisins for an energy boost with this diet. This diet is generally not adviced for a long-term option.

Low-carb - High-protein, low carb diets based on fish and fruit. The good news is that eating alot of fish is very good for you, it is high in vitamins A and D and help reduce the risk of cancer. You may, however, miss out on important vitamins and minerals like calcium and iron.

The Yo-Yo Diet - Dropping a lot of weight in a hurry and then allowing it to pile back on (or vice versa) can be very unhealthy. Anyone eating like this is risking coronary heart disease when they get older. Yo-Yo dieting also encourages the body to store more fat, incresing the risk of heart disease.

The Zone diet - This diet advices eating 30 per cent protein, 60 per cent carbohydrates and bout 10 per cent 'good fats' such as olive oil. The diet insists on strict portion control. High levels of protein could put you at risk of kidney damage. Too little fat can leave you with dry, dull skin and hair, and can even increase the risk of cancer and heart disease. You should try eating more nuts and avocados if you try this diet.

Macrobiotic - An eating plan that bans meat, dairy products, proccessed food, alcohol and caffeine. Although this diet is very healthy and aids concentration as well as boosting your libido, there's no logic in cutting out milk (it's an important source of calcium). By banning meat you are also at risk of anaemia. Meat contains lots of iron, which prevents tiredness, sensitivity to cold and physical weakness.

Weightwatchers - A calorie-controlled diet. Complex carbohydrates give long-lasting energy and provide plenty of vibre and vitamins. This is a very well-balanced diet and steadys your metabolism.
