-Trisha D.

The Science

Our flexible dieting solution is based on the scientifically established Mifflin, M. D., St Jeor formula for determining your REE and TDEE. It is also based on another respected article published in The Journal of the American Medical Association that supports the theory of no foods being forbidden as long as they don’t push you over your established TDEE.
