As this is a weight loss program with a lot of personal autonomy involved, your weight loss is dependent on your adherence to the program, how much weight you have to lose, and other medical/lifestyle factors. We can only guarantee an upper limit of weight loss on any of our program lengths (up to 15kgs in 43 days for example). If you stick to the program 100%, ask for support when needed, and are realistic about your goals… you won't be disappointed!
