the theory: This is the opposite principle of the Sugar Busters diet and actually encourages consumption of sugar as part of an overall calorie-controlled diet.Written by a state registered dietician, the diet—while gimmicky--does promote the message of moderation, allowing sugary foods to be eaten on a regular basis.

the plan
The principle behind the System S diet is that in order to lose weight we need to increase our consumption of carbohydrates. To do this without making the diet heavy and bland tasting, we need to eat 'carb boosters,' such as Jaffa Cakes, Sugar Puffs and dried fruit, which will help keep our blood sugar levels stable and give us energy.

upside
If you have a sweet tooth, you can indulge in sugary foods as part of the diet plan without feeling guilty and still lose weight.

downside
As with any diet plan, you will still need to reduce your overall calorie intake in order to lose weight.
