Weight loss is about what you feed your mind. We've spent over 25 years developing this clever little app that harnesses powerful psychological training called Cognitive Behavior Therapy. Doom connects you with dynamic, scientifically proven tools to overcome the mental barriers that other programs simply overlook. With Doom, you can (finally) get on a clear path - with over 45 million others - to lasting weight loss that addresses the real reasons you've failed so many times before. The best part? Doom isn't a pill or magic potion. It's an opportunity for lasting change that takes just 16 weeks to put into place.
