I too needed to add protein to my diet - when I *finally* got it figured out, I started to see the results I wanted! I aim for 12-16g per meal or snack. Yes, that's EVERY time I eat. Took a lot bit of getting used to, but now it's habit for me. There are the obvious chicken breast, lean fish, turkey, etc. Other than the "usual" these are some of my favorite choices:
Kashi go-lean cereal - 10g of soy protein per serving (1pt) (this is how I start my day - with 1/2 cup low fat milk...)
1/2 cup low fat cottage cheese - 12 g (2pt)
3 eggs whites 10g (1pt)
Tuna fish - 22 g (2 pts)
Protein powder (used in smoothie) 12 g (2pt)
Protien bars (Zone choc. coconut - yum!) 16g (4pt)
Luna Bars (again, YUM) 12g (3pt)
Beware of cheeses (string cheese for example) - they don't have a very high protein count for the # of points. Also, make sure you're looking at COMPLETE proteins - grain products will list protein on the nutrition label, but they aren't the same.
