Q: I weigh 210 pounds.How many grams of protein should I get per pound of body weight?.Some say 0.45, others say 1.5.I`m confused.I play 9 hours of doubles badminton each week.

A: A good target for somebody who is physically active is to get about 1 gram of protein per pound of bodyweight daily (so about 200 grams of protein daily). There has been a lot of research suggesting that physically active people can benefit from that much. There is some evidence that even more protein can be useful if you are actively trying to build muscle and/or lose fat, but the evidence there is not as strong. I would make 200 grams of protein daily as your goal and count each day that you get at least 150 grams of protein as success. Of course, don't forget about the rest of your diet -- getting enough protein won't help you much if the rest of your diet is junk.
