Lyssa Weiss, M.S., R.D., and C.D.N., holds a degree in nutrition from Columbia University and was a staff nutritionist at St. Luke's-Roosevelt Hospital VanItallie Center for Nutrition and Weight Management in New York City. She is a weight management and obesity specialist and the owner of Skinny Jeans Nutrition. But Lyssa's weight loss secrets don't just stem from her degrees. Lyssa developed the Skinny Jeans Diet to combat her own issues with weight loss and food. That was thirteen years, fifty pounds, and four jean sizes ago, when Lyssa took control of her life for good and learned that she could fit into her favorite skinny jeans forever.
