Some years ago, my sweetheart put on several stones and became alarmed. She joined Weightwatchers, did a lot of exercise and managed to get to her goal in about six months. During this time, she ate quite a lot of Weightwathers meals, supplementing them with Weightwatchers desserts and snacks. More recently she lost weight to the point she didn't look well and I've been doing my best to build her back up to a healthy weight. It seems we've slightly overdone it because despite her good looks, she says she is 9LBs overweight and has rejoined Weightwatchers. Each time she attends a meeting, she returns with stuff she wouldn't normally eat. Snacks like low fat crisps crisps and healthier chocolate bars. I'm certain this entices her to consume more. What's it all about?
