Some of us may need more, while others get more than enoughbut more isnt necessarily harmful.

Heres how to figure it all out.

Most Americans eat more than that.

Studies like that one have led to a sort-of myth that we areall eating too much protein.

Its more correct to say that on average we are eatingmore than enoughprotein.

Thats a good thing!

After all, we wouldnt want to eat less than enough.

And its only the minimum for people living an averagely sedentary life.

Again, thats nottoo much; its within the range that their body can put to good use.

This range goes up to 0.82 g/lb, depending on the athlete and their sport.

Thats 123 grams for a 150-pound person, or 164 grams for a 200-pound person.

The extra protein wont hurt you, but it could make you gain weight.

Heres whats going on in your body.

They list kidney disease, cancer, and kidney stones as downsides of a high protein diet.

But we need to remember thatproteinis not the same thing asmeat.

That makes the strain idea a tough sell.

Thats your enough.Track what you eatto see to it youre getting an amount close to that.

Then, to find your personal too much, look at your calories.
