Well the Primal diet is full of veggies, fruits , etc and not as big on the protein as long time ago they didn't have protein everyday due to sometimes on the hunts they didn't find any, so that is the bases . I've also gone back to comparing Sugar Busters which I' ve done 10-12 years ago when it came out since i was so in love with sweets and that is a good one . So I"{m doing a combo using info from both books, exercising more and now that after lots of glucose tests they did an A1C and i"m on the borer line of pre diabetic I really have to do it . So let me know of your successes so far , I've lost 8 pounds in the last 2 + weeks.
