Some people eat what they like and remain slim and vigorous after decades of unchanged eating habits while others wonder why, as vegetarians, they seem to experience weight gain and fatigue. I came across Sears' book and echoed the same sentiments that appeared in the January 1997 issue of Vegetarian Times , where Karen Cope Straus, Food Editor, offers a positive summary to vegetarian readers who might be contemplating Sears' pro-protein stance. Sears, like other protein-diet advocates, blames obesity on carbohydrate intake, which he claims causes insulin resistance.
Carbohydrates come in different shapes and sizes but all are starches.
Some starches are simple, like the potato, but as a simple starch, it transforms directly into sugar in the blood stream and can cause problems for diabetics just like candy would. This condition causes the body to store more fat and prevents the release of previously stored fat. The glucose remains in the liver instead of feeding the brain. People who have this insulin response to high-carbohydrate meals are said to be predisposed to obesity and other serious health risks. Heredity determines the level of insulin resistance in each person.
