The program is explained fully here:http://www.drmcdougall.com/free.html
And I very much recommend that you get at least one book of Dr. McD's like this one:http://www.drmcdougall.com/store_starch_solution.html
But basically. . .
No meat (includes fish, chicken, etc.)
No dairy (no milk, cheese, yogurt, butter, etc)
No oil of any kind
Eat lots of:
Whole complex carbs/starches (brown rice, oatmeal, other whole grains, potatoes, corn) in their natural states
Green and yellow veggies
Lightly processed foods (whole grain bread or pasta)
Eat only a little:
Calorie dense foods in their natural states (nuts, avocados)
And ENJOY GREAT HEALTH!
