Obesity rates have reached epidemic levels in many countries, with an estimated 32% of American adults considered obese. Every year, many of them try countless new dieting fads, exercise regimens, and questionable dietary supplements, but their motivation often sputters out as they see slow results. In the last few years, many of these determined individuals have turned to YouTube to share their weightloss journeys with their peers, who often respond with heartfelt and supportive comments. But YouTube doesn't offer a dedicated community for the weightloss crowd, so its functionality is limited. WatchMEmelt , a TC50 DemoPit company that launches tomorrow, is looking to fill this niche with a community site dedicated to helping users chronicle their weight-loss efforts.
