The Sugar Busters Diet Book works on the theory that foods high in sugars are likely to increase your insulin levels and therefore cause a subsequent increase in weight gain.
On this basis, the diet restricts all refined sugars as well as white flour and any related products and it also encourages the intake of foods that are low on the glycemic index.
The diet is made up of 30% protein, 40% fat and 30% carbohydrate.
Foods on the restricted list apart from the obvious refined sugars, include white bread, white rice, potatoes, corn, carrots and even some fruits including bananas, pineapple and raisins.
Beer is restricted completely although a glass of wine is acceptable at meal time.
Pretty much anything high on the glycemic index is a no-no on this diet.
So what can you eat?  Well you can eat meats, eggs and fish, whole grain products, legumes and low fat dairy products as well as any non-restricted fruits and vegetables.
Any meat eaten must be lean with all excess fat removed and you must remove the skin from chicken.
Although this diet is simplistic in it's approach it does have some drawbacks.
Firstly, there is no still no real conclusive evidence to indicate that a high sugar diet causes weight gain.
The fact that the diet does assist in weight loss is purely based on the fact that it is essentially a low calorie diet and any low calorie diet will result in weight loss.
Secondly, the diet isn't specific enough in terms of portion control and there are a number of contradictions within the book about what can and cannot be eaten.
This leaves the diet open to interpretation by the user which can result in the dieter taking advantage of any possible opportunity to eat more of the wrong foods.
