How much protein in your diet is enough?

Have you been told you need more protein?

Have you wondered if you are eating enough of it?

The supplement industry, magazines, websites, trainers, and athletes (1-2) heavily promote high protein diets. But these popular opinions do not necessarily match up with the recommendations by scientists.

Let’s do some math together.

How much protein do we need?

The current Recommended Dietary Allowance (RDA) is 0.8g of protein per kg bodyweight per day. (2-3) Supposedly, this is “the average daily intake level that is sufficient to meet the nutrient requirement for nearly all (98%) healthy individuals.”

To make it simple,

your weight (lbs) / 2.2 x 0.8 = how much protein you need a day

For an average American male who weighs 195 lbs (4), he needs 71 grams/day. An average American female, who weighs 166 lbs (4), needs 60 grams/day.

How much protein do Americans actually consume?

According to a 2015 study, 98 grams for men and 67 grams for women. (5)

Remember that the average male only needs about 71 g and female 60 g according to our previous calculation.

What about active individuals? Do they need more protein?

This is still a debatable question. There continues to be conflicting recommendations between US Dietary Reference Intakes and the US Dietetic Association. (2,3)

Generally 1.2-1.3g/kg/day (instead of 0.8g/kg/day) of protein intake is considered enough for athletes and individuals with moderate physical activity level. (6,7)

If we do a quick calculation, that is 106 grams for a male athlete with an average weight of 195 lbs. 106 grams is not too far off from the 98 grams average American males are consuming already.

For female it is a different story. 90 grams is quite a bit more than 67grams, which is what average American women consume a day. The good news is that the difference is nothing an omelet cannot make up for.

So if you are a woman who exercises regularly, you may want to pay a bit more attention to your protein intake.

Keep in mind that protein does not only come from meat and beans. A cup of cooked oatmeal contains 6g of protein. A bagel contains 10g. One cup of cooked white rice contains over 4g. My point is, you are probably eating than you thought you were.

Bottom line
  • Extra protein is converted to fat. (8)
  • Too much protein is associated with (1)
  1. bone loss
  2. kidney disorders
  3. cancer
  4. liver disorders
  5. coronary artery disease
  • Plant-based protein may reduce cardiovascular disease risk (9)
  • As of now, there is no reasonable scientific data supporting a high protein diet due to potential disease risks (1)
