I know it’s possible, but I’ve never had great success in losing weight. I’ve joined some online groups in the past, and been incredibly discouraged when everyone else seems to report the weight simply melting off, and I’m the one who loses maybe a pound or two. Very discouraging. I’m not at my very tippy-top weight any more - about ten pounds below it - and need to lose 50 pounds to get into the very top of the “normal” range for my height and build. I detest “fad diets” and think the common sense way - eat less, exercise more - is the way to go. Not glamorous, not sexy, not publication-worthy, but probably more effective in the long run.
