I have been using Diet Doctor for 3 years, now is better than every. Great library of videos, fantastic receipts and meal plans, good education, community. APP is such a great addition to the website.
I am endocrinologist and Diet Doctor is the best resource I have on this topic. I greatly appreciate info provided in different languages especially Spanish. It is practical and great for ALL levels, from beginners to advanced. Highly recommend this web side to all interested.
