Question : How much protein is too much protein?

Someone just tweeted me asking if it’s possible to eat too much protein.

It definitely is.

Eating a diet primarily based on protein is not good for you, and your body will not thank you for it.  You won’t look better, and you won’t feel better. Even Brock Lesnar (UFC fighter, performance athlete, human wall) blames his almost exclusively protein diet for the illness that retired him – Diverticulitis.

I currently weigh 13 stone (182 lbs) and I shoot for 182 grams of protein per day, so 1 gram per lb of bodyweight.  Some extremely clever people at the University of Connecticut (Yeah, I’m a bit international) and the ISSN (International Society of Sports Nutrition) suggest between 1.4 and 2 grams of protein per kg of bodyweight.  That would be somewhere in the region of 114 – 164 grams of protein per day for me.

Before you go overdoing it on the protein, remember this :

  • Eating more than 1 gram of protein per lb (or 2 grams per kilogram, roughly) of bodyweight has NOT BEEN PROVEN (at all, really) to build any more muscle than lower amounts.
  • Eating more than 1.36 grams of protein per lb (3 grams of protein per kilogram, roughly) of bodyweight can seriously affect your kidneys.  Don’t fuck your kidneys up, period.

I know the meathead at the gym is telling you to eat 500 grams of protein every day, and to drink raw eggs like Rocky Balboa – but really – don’t do it, it’ll hurt you in the long run.
