I’ve gone through this “diet” three times (see graphs). The first time I went from 83kg to 75.5kg over about 3 months. The second time, from 80kg to 71kg over 4 months. My latest iteration of this diet has me down from 75kg to 68.5kg in about 2 months. Note how each time the starting weight is over the last ending weight? And this is the problem, right there. It is not hard to find an eating regime that will help you…
There's a lengthy period of time which I haven't typed in the data for where I just weighed myself every day. I still managed to keep the weight off when I did that. The minute I stopped weighing myself, though, the weight piled back on.
A daily ritual of stepping on a scale seems a small price to pay for not needing to worry about weight gain, though.
