The G.I. Diet: How It Works

With the glycemic index in the core, the G.I. Diet by Rick Gallop is based on the principles of the theory commonly known as the glycemic index, which was suggested in 1981 by David Jenkins. Naturally, the G.I. Diet works by promoting the ideas of glycemic index. Thus, a dieter is encouraged to choose products with low GI, which make him feel fuller for longer periods of time and avoid food options with the high glycemic index, which cause sudden changes of blood sugar level.

By the way, the G.I. Diet by Rick Gallop is not the only diet, which put the ideas of Dr. Jenkins into the basement of its own weight-loss program. South Beach, Atkins and many other popular diets refer to glycemic index to a greater or lesser extent. All of those diets use foods glycemic index in order to compose a menu, which would keep a dieter full and which would not raise the blood sugar - the underlying cause of certain diseases and a major culprit of the desire to eat more and more. So, in order to understand how the G.I. Diet and other diets based on the glycemic index work it is necessary to reveal the secrets of the glycemic index itself.

Well, the puzzle of the glycemic index is not much complicated. In fact, it is just a scale, which shows how much and how quickly different types of foods (mainly carbohydrates) increase the sugar level in blood.

Imagine that our daily menu is like city roads with different types of cars, driving at different speeds. Naturally, driving at the extreme speed increases the chances to get into a car crash; on the other hand, driving too slow increases the chances to be always late, which can also bring many troubles. That is why it is recommended to choose moderate speed while driving a car and always mind the road conditions. In other words, glycemic index says whether a particular food is an old Ford or a brand-new Ferrari, and the G. I. Diet teaches all its followers to prefer old Fords to Ferraris when choosing foods to eat.

By the way, there is one more symbol from the traffic regulations in the G.I. Diet. It is a traffic light, which says whether a particular product is allowed to consume off-limits (green light), or it should be eaten occasionally in moderate amounts (yellow light), or it is safer to avoid such a food option (red light). Such food categorization is based on the glycemic index of each food option: the higher glycemic index - the better a food product suits the "red" group.

So, all those traffic light techniques are used in the G.I. Diet to show a dieter what types of food are beneficial and what are not. The diet encourages all the people to consume low-glycemic products and avoid those with the high index. Such approach ensures a dieter not to be deprived while following the diet (it is because low glycemic foods require more time to be digested in the human body, thus making one feel fuller for a longer period of time). Furthermore, promoting low-glycemic foods, the G.I. Diet works to reduce cravings to eat more and more (it is because unlike high-glycemic products, low glycemic food options do not cause the rapid increase of blood sugar, which is usually followed by feeling the necessity to have another portion of carbohydrates).

Finally, it should be noted that in spite of the central role of the glycemic index in the G.I. Diet, it is not an absolute dogma in differentiating “good” and “bad” products. The diet also takes into account the amount of calories and fats in the food, thus promoting an eating plan, where the total amount of calories, as well as the amount and nature of fats, are under control. For example, peanuts covered with chocolate have low glycemic index; however, such candies are placed into the "red" group in the G.I. Diet, because of their caloric load and fatty ingredients.
