I think this thread is another in the same vein of ones we see nearly every day on here, Fat people are wrong
They're wrong for being fat in the first place and then they're wrong for losing weight in the wrong way.
Just wrong'uns all round
And as evidenced by posts above, there is a belief, god knows where from, that somehow drugs (or surgery, this often is said about WLS) just make you lose weight in and of themselves.
YOU STILL HAVE TO EAT LESS!!
And whatever route you take, SW, WW, Jane Plan, Cambridge Diet, Slim Fast, fasting, calorie counting, low carb, low fat, surgery, medication, you still just eat less than you need and that loses you weight. Some of those routes can be tolerated better by some, one size does not fit all and there should be no shaming and judging for how someone loses weight, its bloody hard work all round and life long for most of us.
