How much protein are we suppose to have in a day? I have been doing weight watchers and I am not sure how much to too much protein. I usually have about 3-4 oz at lunch and about 4-5 oz at dinner. Is that too much?
Thanks for the reply

Probably too much - aim for 3-4 oz/day

The US RDA is .8 g protein per kilogram (2.2 pounds) of body weight for a normal person.

175 pound person = 80 kilograms x .8 = 64 g of protein needed
64g = 2.25 oz.

Another way to calculate is by calories. On a 1500 calorie diet, if about 30 percent of your calories come from protein, that's 450 calories from protein. Protein has 4 calories per gram.

450 calories = 112 grams of protein = 4 oz

When people start consuming too much protein (over 2.0 g/kg/d), the extra protein can become a stressful stimulus for the kidney. This is even more of a concern as we get older and our organs are less efficient and effective.

80 kg x 2 g protein/kg = 160 g = 5.6 oz

Just saying one gram per pound of bodyweight is easier, and certainly isn't bad for you.

How much potein

Is there even one study out there that shows that healthy people with healthy kidneys have kidney stress from eating too much protein? Since farming didn't start untill about 10,000 years ago, did the ice-age man have kidney stress?

1g per pound is for men trying to build muscle, not for women trying to lose weight.

When I followed The Zone guidelines of 30% of calories (110g protein for 1500 cals/day), I stopped losing after the initial 15 lbs. Then I switched to a more mainstream guideline of 20% of my caloric intake. At 1500 calories a day, this translates to 6oz meat or cheese (42g protein) because meeting my requirements for dairy/milk adds another 12g and there's always a little protein in starches and veggies. The weight started coming off again.
