Will therapy help? Or Hypnotherapy?

It took me 20 years of trying every approach in the world until finally I discovered a book by Dr. Dean Ornish "Eat More, Weigh Less" and learned that I could lose weight without a therapist, hypnotherapist, or weight loss clinic, or spending thousands of dollars on a medically supervised weight loss program.. ( These didn't work for me, and according to Gina Kolata, medically supervised diets, calorie restricted diets, Atkins, and other commercial programs are ineffective in the long-run). I lost 80+ pounds over the past three years without much effort thanks to a low-fat, whole plant based diet endorsed by some of the most respected nutritional researchers in the country.
