I'm 54-went on low carb about 10 years ago, and lost 30lbs rather quickly, in about 6 weeks, but I had 2 jobs, one sedentary and the other moving all the time, so, I'm sure that helped. Now, I sit at a desk most of the week, but busy all day on the weekends. Quit smoking and gained 15-20lbs quick, and want it gone!
