There's no absolute answer for how many grams of protein a woman should get each day — 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. If you don't see your weight, just use the formula above to calculate your daily protein.

Weight (lbs) Weight (kg) Protein per day (not very active) Protein per day (active or pregnant) Protein per day (extremely active)
100 45.5 36.4 g 59.2 g 81.9 g
105 47.7 38.2 g 62 g 85.9 g
110 50 40 g 65 g 90 g
115 52.3 41.8 g 68 g 94.1 g
120 54.5 43.6 g 70.9 g 98.1 g
125 56.8 45.4 g 73.8 g 102.2 g
130 59.1 47.3 g 76.8 g 106.4 g
135 61.4 49.1 g 79.8 g 110.5 g
140 63.6 50.9 g 82.7 g 114.5 g
145 65.9 52.7 g 85.7 g 118.6 g
150 68.2 54.7 g 88.7 g 122.8 g
155 70.5 56.4 g 91.7 g 126.9 g
160 72.7 58.2 g 94.5 g 130.8 g
165 75 60 g 97.5 g 135 g

Based on the numbers above, do you already get enough protein per day?

The recommendations that are on the high end still seem too low. If you're trying to add muscle, you typically need 1g of protein per pound of bodyweight.

Protein Intake is high, stay hydrated.

Man, after going to a trainer, he told me that I should be eating over 100 grams of protein, and I thought he was crazy! I definitely have only been eating like 60 grams of protein. Maybe that's why I feel tired and "hung over" the day after an intense workout.

When you eat too much protein, water is taken away from your large organs to digest an breakdown the protein, which causes your organs harm, and begin to shut down

I'm new to this site, but it sounds just like what I need. I'm 68 just diagnois with diabetes and I'm a kidney transplant patient. I would really like to see some diet that would help keep me from going on insulin. Any ideas or suggestions would really be helpful. Thanks , Sunny

I had a friend that went on a low carb. high (animal) protein diet. She lost a lot of weight, but was hospitalized for about 3 weeks during the diet because he liver failed. I have a feeling she was basically only eating meat, and nothing else. Of course it is an extreme case, but I think some one asked what might happen if you consumed too much protein.

ok so I go to school in the morning, come home and workout for about an hour and a half, then go to work for 8 hours loading airplanes, so it's pretty strenuous work. I wouldn't call my workouts intense, but I work out 5 times a week as well as all that other stuff. So my question is, does this constitute an "extremely active" lifestyle? Should I be eating .54 grams of protein per pound of body weight?

I probably eat 2 pounds of meat a day, sometimes more: I wonder HOW BAD/GOOD that is for me...hmmm!? I do not eat any fatty gross meats though like pig...
