The most incredible weight loss transformations of all time

"Sometimes people can feel unmotivated because they lose sight of why they're making changes in the first place," says Edwina Clark, R.D., head of nutrition and wellness at Yummly. The reason why you're losing weight should be as specific and unique to you as possible. Not only will having a mission statement on tap help you build momentum in the beginning, it will help you refocus after any setbacks you experience along the way.
