The Sugar Busters diet requires dieters to avoid food with more than three grams of sugar per serving and to limit carbohydrates to two or three daily servings of whole-grain products. The guidelines encourage dieters to eat vegetables, lean protein and most types of fruit. The guidelines also allow dieters to eat low-fat or fat-free dairy products and healthy fats such as olive oil, walnut oil and canola oil.
The Sugar Busters diet discourages consumption of all types of sugar, including honey, corn syrup, molasses and dextrose. The diet makes exceptions for the naturally-occurring sugars found in fruits and dairy; however, it discourage dieters from eating raisins, bananas, watermelons and pineapple due to these fruits' high sugar content.
The Sugar Busters Diet was created by a group of doctors and a Fortune 500 CEO in the 1990s. The diet limits sugar intake in an effort to reduce the body's production of insulin, as too much insulin can trigger weight gain. Most of the diet's prohibited foods score highly on the Glycemic Index and cause blood sugar levels to rise when consumed.
Some nutritionists point out that sugar is not actually toxic and suggest that the Sugar Busters diet forces dieters to avoid foods that are actually healthy.
