GI is the glycaemic index. All foods are measured against glucose, which has a GI of 100. It's a measure of how quickly the body converts what you eat into insulin The theory goes that the more high GI foods you consume (white bread, cakes etc) the harder your poor old pancreas has to work, and ends up converting what it doesn't use into fat. Put simply it teaches most of the stuff we already knew, that highly processed, refined carbs are a problem, all foods in balance are fine, etc and to have a healthy diet you need to concentrate on good quality carbs, plenty of high quality protein, and fruits and vegetables. There are some really good books out there with low GI principles. One of the interesting things it is the whole meal that you look at in terms of GI foods. So tonight for example I had a bagel, which is medium with a grilled chicken breast, mushroom, courgette and peppers, all medium and low foods, so the overall profile is low.
The beauty of eating low GI is that you don't have the peaks and troughs in your blood sugar and are more unlikely to demolish a packet of Jaffa cakes at 4 in the afternoon (but not totally immune) I have found I have had a lot more energy and my moods have certainly improved, just ask the DH.
Unfortunately, the GI diet does not feature young men in 50's US Army uniforms, but if you find some, you have to share!!!!!!!!!!!!!!
