how many g of protein per day
There's no absolute answer for how many grams of protein a woman should get each day â it depends on your weight, your activity level, and whether or not you're pregnant. But with a little elementary-school math, there's an easy way to calculate the number of protein grams that's right for you. Take your weight in pounds and divide it by 2.2 to figure out your weight in kilograms. Then multiply that number by 0.8 (not very active), 1.3 (active or pregnant), or 1.8 (extremely active), depending on how much exercise you get. As a general guideline, the CDC's average requirement of protein for women ages 19 to 70 is 46 grams per day. But, as you can see from this chart, you'll need to increase that if you're expecting or training for a marathon. Check out the chart below to see how much protein you should be eating each day.
