Mice Given an Experimental Gene Therapy Don't Get Fat (boingboing.net)
AmiMoJo shares a report from Boing Boing: Researchers at Flinders University knocked out a gene known as RCAN1 in mice, hypothesizing that this would increase "non-shivering thermogenesis," which "expends calories as heat rather than storing them as fat" -- the mice were fed a high-calorie diet and did not gain weight. In particular, the modified mice did not store fat around their middles -- a phenomenon associated with many health risks, including cardiac problems -- and their resting muscles burned more calories.
[Vice News reports:] The study's authors point out that there's a time and place for RCAN1's role in preventing calories from being burned: namely, back when food was scarce and calories weren't so readily available. In the modern world of "caloric abundance," however, too much fat is being stored and real health problems are ensuing as a result. The researchers suggest that "These adaptive avenues of energy expenditure [such as RCAN1] may now contribute to the growing epidemic of obesity." "We looked at a variety of different diets with various time spans from eight weeks up to six months," said Damien, "and in every case we saw health improvements in the absence of the RCAN1 gene. "Mice on a high-fat diet that lacked this gene gained no weight."

It's not ideal for long term use, but as a way to lose weight it's very promising.
The reason why fat people find it so hard to lose weight and keep it off is that the body fights them. When they cut down their calorie intake it goes into starvation mode. They feel tried all the time and it reduces burn to a minimum, which ends up meaning they need to diet extremely aggressively to get anywhere and will likely be unable to keep the weight off. 1500 calories/day is neither healthy nor sustainable, but in starvation mode that's what they need to achieve.
This gene seems to fix that. Say it could be turned on and off at will, or perhaps turned off but then the body regulated with medication instead. People could maintain a healthy 2500 calories/day diet with all the nutrition they need, and still lose weight and then maintain at that level.

Way back in the day Michelin was looking to increase sales and one way to do that was to get people to buy cars and drive more (hence more tires sold) and they needed a reason for people to want a car. So Michelin started reviewing restaurants (awarding them Michelin stars which are still given out today and considered somewhat prestigious) with the thinking that people would want to buy a car or use it more if they could have an exceptional dining experience.
