As a much less drastic alternative to gastric bypass for weight loss, dentists have started offering the DDS system - an attachment that fits into your mouth and prevents you from eating too much.

It costs about four or five hundred dollars to install. But some people wonder if it would be very effective. Here's one's persons comments;

"I had a retainer when I had my braces off and it looked similar to that thing. It did help me eat slower when I had to wear it 24/7, but after that, I took it out whenever I could. I can imagine people buying it and using it maybe once and then deciding it doesn't work because they STILL ate the whole bag of Doritos, so they stick it in a drawer and chalk it up as another failed dieting gimmick. You can out-think any weight loss plan if you try hard enough...I know a woman who gained back much of her gastric bypass weight by drinking milkshakes and eating very calorie-dense foods and basically not really complying to any of the rules she was supposed to follow. This little DDS thingie just proves that 99% of weight loss is a mental thing, not just a physical barrier."
