GI stands for Glycaemic Index, which is a measure of the energy levels of carbohydrate foods and the rate at which your body uses them. Not all carbohydrate foods are the same and are rated on a scale of 100 in the index. The higher the GI, the quicker the food is absorbed and used and the sooner you feel hungry again. Low-GI foods means the energy stored in your body after digestion as glycogen lasts longer.

So low- and medium-GI foods are the ones to aim for. But you must also watch what the GI foods are cooked with.

Does it work? Good for those with an active lifestyle, as the slow-release energy of low-GI foods means less snacking in between meals. It's a long-term eating plan that you should stick with for life, so in theory you won't have to diet again!

Pros Low- and medium-GI foods are varied and plentiful. Oats, pasta, basmati rice, nuts, fruits, lots of vegetables, pulses, sweetcorn, muesli and brown bread should make up 70% of your diet, which is easy. Dairy foods (except skimmed milk), red meats, cakes and chocolates should form about a tenth of your daily intake. Processed foods are not encouraged, but occasional use won't make you veer off course.

Cons You have to memorize lists of what is low and medium GI. Weight loss is slow, but once it's off it stays off, if you stick to the same good foods.

Verdict: It works if you can be strict with yourself enough to allow the time it takes to lose the weight. I recommend using the G.I. Diet in conjunction with my Personalized Prescription Weight Loss Pills for the most effective diet. The Glycaemic Index list is available to my patients. When they order. It wont work right away by itself and takes time to curb your desires enough for it to take effect.
