20. Tuna

Low in both fat and calories, tuna is a lunchtime favorite that is almost pure protein. Tuna might not be quite as high in those healthy omega-3 fatty acids as some other fish, like salmon, but it still packs a wallop of nutrition. One cup of tuna, packed in water, has 39 grams of protein but only 179 calories.

21. Beef

There is no denying it; beef is loaded with highly bioavailable iron, B12, and other nutrients. Just one serving (3 ounces) of cooked beef containing 10 percent fat has 22 grams of protein and only 184 calories.

Eating a diet high in protein and low in carbs is one of the best ways to keep your weight down while giving you longer lasting energy to keep you going all day long.
