Although lots of experts disapprove of low carb diets for health reasons, many, particularly those who love bacon and eggs, may find it works for them. But it's not a long-term diet.
What is it?There are lots of different low-carb diets around but the Atkins Diet is perhaps the most famous. Carbohydrates consist of sugar, starches and fibre and are found naturally in lots of foods such as fruit, veg, wholegrain cereals and brown rice.
A low-carb diet is where you restrict the number of carbs you eat, replacing them with protein rich foods like meat and cheese.
How does it work?Our bodies break down carbohydrates and fats into sugar which then gives us energy. Low-carb diets are based on the idea that if we don't eat carbohydrates, our body will use stored fat for energy instead.
