I have finally lost 40+ pounds eating primarily raw foods! I especially enjoy my raw fudge made from medjool dates, walnuts and/or coconut oil, and raw carob. I also try to eat avocados as much as possible which is probably just one or two a week in my salads or smoothies! If I use any oil it is olive oil. But I also use nuts as a base to make a fantastic dressing.
I had tried for a long time to lose weight before i became a vegan, but nothing worked even though I would eat about 1800 calories a day for well over a year! In retrospect, I know that the stresses I was under was the primary reason, but now I am no longer pre-diabetic and don't feel as anxious as I used to feel eating a nutritious diet but with some meat and very little dairy!
