Can SuperFastDiet be used to lose a small amount of weight (2-5kg)?

Yes. In a recent study, scientists showed that normal weight and slightly overweight people can use the diet to drop the last 2-5kg, and achieve their ideal weight. Just keep in mind that as you are close to your ideal weight, your weight loss will likely be quite slow (about 0.45kg per week). To speed up the weight loss, you may choose to add in an extra fast day, or some extra exercise sessions each week.
