Slender Wonder is a medical weight loss programme which is safe and effective. The programme helps to treat the cause of weight gain and helps to reset one’s “lipostat”, making it easier to lose weight and keep the weight off in the future. Weight loss on the programme is rapid (3-10 kg per month) and there is no rebound weight gain afterwards. The programme consists of 3 components, namely a calorie-controlled diet, supplements, and daily injections. An initial consultation with our doctor is necessary before starting Slender Wonder.
