Serve with mashed potatoes, rice or noodles - add canned green beans and a sliced fresh tomato to plate and voila - quick and tasty for 3 or 4 people.

So gist of GI diet is to focus on low GI value foods, as these are ones that will keep you going for longer without hunger rearing it's ugly head! A 'low' value is generally thought to be below about 55 on GI scale, while 'medium' foods are between 56 and 69. Above 70, and food is a high GI value. Obviously, on GI diet, you focus on low GI value foods, keeping your blood sugar at a constant level and holding hunger pangs at arms length. You should generally cut down on fat-laden foods too, even if technically they are 'low' GI foods. Milk, chips and chocolate are examples of this.

You have probably already spotted main problem with GI diet - it can be hard to tell what GI value of an entire meal is, given that a meal has several component foods. Unless you are careful, you could end up following what looks like a good GI diet, but is actually packed out with fat and salt - hardly healthy! This is why meal plans are essential on GI diet. On a good GI diet plan, you should expect to lose 1 or 2 pounds a week, and this is a pretty sustainable level to aim for, according to leading nutritionists. A GI Diet may also (although research is not conclusive yet!) help ward off certain types of diabetes, and heart disease too.

Like all diets, you should check with your doctor first, to make sure you aren't running any health risks unnecessarily. A typical 'good' GI diet plan for a day might look something like this (more detailed plans are, of course available at www.supadiet.com ).
