I agree with Diana. It IS sad when people think this is their last option because they can't seem to lose weight any other way. Usually it's not their fault, it's our Government's fault by pushing the high carb, low fat diet on us. However some overweight people don't look for other options. I personally know a few over weight people who, when a low carb diet was suggested to them, reacted in horror because 'they couldn't bear to give up bread.'
