"[Turmeric is] nature's strongest anti-inflammatory [and has] been proven as effective as over 14 different prescription medications without any negative side effects," says Dr. Aviana.

"Remember, all weight gain, but especially in the 'hard to lose' areas like the belly, glutes, thighs, triceps, neck, and chin is directly related to the health and function of your lymphatic system.
