 but not sure where to start. I understand. I was right where you were two years ago. Let me tell you why I chose my PhD weight loss. First, Dr. Ashley Lucas has her PhD in chronic disease and sports nutrition. Her program is based on years of research and is based in science. Second, the PhD program starts with nutrition, but it's so much more. They know that 90% of permanent change comes from the mind, and they work on eliminating the reason you gain this weight in the first place. No pills, no injections, just solid science-based nutrition.
