For weight gain you should be consuming close to a gram of protein per pound of lean body weight (body weight minus fat). I'd recommend using Cronometer to keep track of your macros.
First off welcome to the forum.
That is a common misconception.
Don't feel bad. I hear that repeated way more often than the actual fact.
At the most you need 0.8 g or protein per pound of body weight.
Most people need much less. The US RDA is 0.36. A study on body builders recommended 0.48. And 0.77 for body builders just starting out.
I think all of the recommendations round up or down to 1 gram of protein per KILOGRAM of body weight. So maybe this is how the misconception started.
A couple of things to keep in mind. More is not better.
Our bodies have no mechanism for storing protein. Excess protein is broken down into amino acids that circulate in the blood stream. Once the body figures out they are excess they are broken down into glucose. Then used for energy or stored as fat.
The breaking down of amino acids results in toxins (nitrogen compounds - like ammonia and urea) ending up in the blood which the kidney and liver have to work hard to remove. Some body builders have damaged their kidney by over consuming protein.
New research is indicating that we have a maximum rate of protein that we can absorb and utilize. This is still somewhat new but the number that seems to be best established is between 20 and 30 g of protein per meal. So probably anything above 30 per meal is just going to be wasted.
Oh, and I just thought of something. Grams of protein are a pretty good goal. But IMHO a better one is measuring protein as a percent of your total calories. I'm also a CronOmeter user. Some people think that 20/60/20 is ideal. I find it almost impossible and have lowered my goals to 15/60/25.
I always like to back up my claims. Below I've linked to an article that is one of the best on busting protein myths. The article itself is well referenced. And it's not that long. So if this is a topic of interest you should read the article.
I've also linked an article about too much protein.
Protein bars, shakes and powder supplements claim to curb appetite, help with weight loss and build muscle. But what’s the real story?
