obesity
"I've been taking alli for 3 weeks (only on week days with a bit of cheating at the weekend) and I've lost half a stone.  You won't get any nasty side effects as long as you limit your fat intake to less than 15g a meal and avoid high fat foods. It's not a miracle drug, you can't just take it with an unhealthy diet (you will get the side effects then!) but with a healthy diet and exercise it increases your rate of weight loss. I think it's worth the money."
