The GI Diet
The GI diet has become popular recently, and has also been endorsed by many doctors and nutritionists.

The GI or GLYCAEMIC INDEX of a carbohydrate rich food depends on how quickly the sugar from the food is released into the blood when the food is eaten and digested. The higher the GI, the faster the sugar is released.

Therefore, when a high GI food, such as sugar, sweets, cakes, biscuits and white bread is eaten, you feel initially satisfied as the sugar is released but very soon, you feel hungry again, as the sugar is rapidly stored in the body. Lower GI foods, such as wholemeal bread and pasta, brown rice, wholegrain cereals, vegetables and some fruits, release their sugar into the blood more slowly, so you feel satisfied for longer.

The overall glycaemic or total GI of a meal is different from the individual GIs. Eating protein or fat together with a high GI food can lower the overall GI of the meal. However, some very fatty or salty foods may have a low GI, so it is important to consider other health issues before adopting the GI diet.

The key to healthy eating is balance and variety, rather than rigidly sticking to any particular 'diet'

DIETING CAN MAKE YOU FAT!

  • A large number of people are currently on a diet but many who lose weight will put it back on again. Constant switching between dieting and gaining weight is unhealthy. The metabolism is confused and in the long term, weight tends to slowly creep up.
  • Traditional diets involve restricting food intake, often involving complex rules and eating only certain food groups (such as protein and fat) or certain food types (such as cabbage soup or grapefruit). They quickly become boring and initial weight loss slows down or weight returns.

The Atkins Diet
The Atkins Diet has received considerable media interest with some celebrity endorsements. It involves eliminating carbohydrate (starchy and sugary foods, plus fruit and veg) from the diet and eating unlimited amounts of protein and fat (meat, fish, eggs, dairy and fats).

  • Weight loss is achieved because protein is very filling and so the dieter is less likely to feel hungry between meals. It is difficult to eat lots of fat on its own without carbohydrate e.g. cheese and butter without bread or potato would be unpalatable, so fewer calories are consumed overall.
  • In the long term, this diet is unhealthy, because the body, especially the brain and muscles, needs carbohydrate (ultimately glucose) to function properly. The dieter will feel tired on the Atkins Diet and may also suffer bad breath, caused by the lack of carbohydrate. It is also thought that the high level of fat may increase cholesterol levels and the large amount of protein might put a strain on the kidney and liver.
  • The key to maintaining a healthy weight is to eat a balanced diet, rich in fruit, vegetables, starchy carbohydrates, low fat dairy products and lean meat. Fatty, sugary and processed foods should be limited but this does not mean avoiding everything that you like.
