The concept of a metabolic set point is a myth based on a misinterpretation of research. Many overweight people — including those with families and jobs — have gotten down to a healthy weight and maintained it permanently purely though lifestyle changes. So please don't claim that it's impossible.
You are one of them, I assume? How much weight did you lose, over what period of time, and what is your weight right now? Are you a doctor by any chance?
