What exactly is a safe limit for taking whey protein? Different websites recommend different amounts of protein intake. The most common one that I see is around 0.8g of protein for every kilograms of weight.
I went to an online calculator for protein requirement and given my body specifications, the calculator recommends that I take 48grams of protein per day. I think my daily usual food can reach 48g of protein easily. In fact, I don't need whey protein to reach 48g of protein, if the calculator is right.
On the other hand, some websites recommend up to over 100g of protein, which is more than twice the recommended protein intake from the calculator!
I weigh about 100 pounds and stand at 5'4. I am a male and have a relatively small and thin body frame. Apart from my recent venture into the gym on some of the days to spend an hour lifting weights, my activity level is pretty sedentary.
I ask because I'm worry that I may either consume too much protein, which may overwork my liver and kidneys, or consume too little protein, which is not most effective for my training in building up muscle size.
At this point, I am taking two scoops of whey protein on days after lifting weights. On other days that I don't lift weights, I take one scoop of whey protein.
So, again, what is a safe gauge for the amount of protein intake so that my body remains healthy and does not need to work extra to flush out the unnecessary proteins?
