One of my problems with trying to maintain a healthy weight is continuing feeling of hunger. The concept of Glycemic Index (G.I.), i.e. how fast food is turned into blood sugar, which in turn causes the pancreas to put out a lot of insulin, which in turn causes extreme hunger,always made sense to me. The problem was, how do you know what is the G.I. of all the food around you. Well this book perfectly listed almost every food that you will be exposed to. Once I selected to only eat really low G.I. foods, my hunger left me right away and my weight started to come off.
The only reason I didn't rate the book a 5 star is something they did that they maybe thought would be helpful but got in the way. They classified all the foods like vegetables, nuts, meats, etc. then within that classification listed them alphabetically. Well that kept getting in my way because, not being a food expert, I couldn't always guess what was the food I was looking for classification. Many times, I thought they hadn't listed the food, but in actuality it I was looking in the wrong clarification. It would have been better if all the foods were simply listed alphabetically. I didn't care about its classification because that had no nutritional impact to me.
