It is not as hard and complicated as you might think. Fish, chicken, and lean red meat. Baked or broiled. Lots of Veggies, the darker green the better.
Fruits are great, especially in the a.m. and in smoothies.
I love smoothies. Sometimes I ll have 2-3 per day. Stay away from fruits at night, to high in sugar. No dry carbs for dinner. Stick with protein and veggies.
