Can you eat too much protein?

[Ben]

I remember reading that too much Protein can increase the acidity of your blood, which in turns leads to the leeching of Calcium from your Bones to lower said acidity.

But I may be remembering wrong or just completely lying...

Put this link in a thread of mine a while ago, was a pretty good read

High-Protein Weight Loss Diets and Purported Adverse Effects: Where is the Evidence?

SpiderDan SpiderDan, does whatever a theory debunker can!

Loren Cordain in the Paleo Diet for Athletes says that you can have protein intakes of up to 40-50% of total calories before you start getting adverse reactions. So, depending on your calories depends on how much protein you can have. On a 3000kcal plan, you could have up to 1500kcal protein, which is almost 400g of pure protein each day. For a 100kg person, thats 4g/kg, which is higher than most people will go.

Personally, I have experimented with just over 3g/kg before (300g/day) and the only negative reactions I got were a weird sweat smell and very regular bowel movements. Fortunately, this bought me valuable "quiet time" away from my lady friend.

It depends on carb amounts, if you run a low to moderate carb diet (less than 200g per day), nitrogen balance is achieved 1.5g protein per kg bodyweight.

If you eat more carbs that goes down to 1.2g.

However this is balance, so if you are trying to build you may still want slightly more, maybe 1.75g per kg. That would still only mean ingesting 175g for a 100kg weight.

However outside of laboratory situations we all know that 175g is not enough for many to build and hard data doesn't substitute experimenting on yourself to see what works. Perhaps knock your protein back to 125g per day. If you are having trouble building at that increase by 25g and reassess, repeat if still no progress. Remember you will need to increase fat or carb intake to make up your calories.
