[Recommended Amount Per Day] Pretty much every resource I've come across recommends that we consume a minimum of 0.8 grams of protein per kilogram of body weight. To figure this out in pounds, just divide your weight by 2.2 and then multiply your answer by 0.8. (For example, a 200lb person would divide 200 by 2.2 and get about 91. They'd then multiply 91 by 0.8 and get about 73. So, this example 200lb person would require a minimum of 73 grams of protein per day.) Of course, the keyword there is minimum, as 0.8g of protein for every kg of body weight is what's required to keep the body from breaking down its own tissues. The USDA recommends that about 15-20 percent of your total calorie intake comes from protein. (This fits with their recommendations of about 50% carbs and 30% fat, which leaves 20% for protein.) 1 gram of protein contains 4 calories. So, let's say an example person is consuming 2000 calories per day. 15-20 percent of 2000 is 300-400 calories. And, since 1 gram of protein contains 4 calories, you'd divide 300-400 by 4 and get 75-100 grams of protein per day for this example person. I will also mention that for those who do some form of intense exercise on a regular basis, there is some research showing the need for a higher protein intake. A recommendation I've seen for these individuals is 1.8 grams of protein per kilogram of body weight per day. Many other resources recommend as much as 1-1.5 grams of protein per pound of body weight for those doing intense weight training regularly. However, for the average healthy adult who won't be doing any form of intense exercise regularly, I like the the USDA's 15-20% of your total calorie intake recommendation, or perhaps my own "average person" recommendation of 0.5 grams of protein per pound of body weight (a 200lb person would do 200 x 0.5 = 100g of protein per day). Anywhere in the range of these two suggestions would be pretty good. [Sources] Chicken, turkey, meat (the leaner the better), fish, eggs, egg whites and, to a somewhat lesser extent, nuts and beans.

Protein Protein plays an important role in muscle, cell and organ function and is necessary for building and repairing the body's tissues. It is present in muscle, hair, skin, bone, and nearly every other body part, which makes protein a very important part of a healthy diet.
