The RDA for protein is extremely conservative. If you're lifting
weights and
dieting, you should aim for 1g of protein for every
pound of bodyweight - or at least per every
pound of your
goal bodyweight. Or you can look at it as a factor of the percentage of your
calories - for example, I try to get my macros to balance out to 40/35/25, which means I get 40% of my
calories from carbs, 35% from protein, and 25% from healthy
fat.
When I do that, I get very close to 1g of protein per
pound of
goal bodyweight: 135g (or so) of protein.
Nutrition is KEY when you're losing weight and working out. And protein will help you feel full for longer as well, so it will help with the cravings and empty feeling that you'd have if you load up on carbs.
