hi there-- jujube recommended you highly for your knowledge, and i was wondering whether you could answer this question:
i started exercise again last week and have been doing some really rigorous stuff. i do some aerobic, like walking or lap swimming, but i've been doing a lot of strength training courses including weights. you wrote that our bodies are always breaking down muscle and need protein to rebuild. i've been trying to take in more protein than before since it's also important to toning and weight loss. despite all the exercise and the negative calorie balance, i've gained a pound or two. my kidneys have been doing poorly lately. i'm wondering whether the breakdown of muscle from exercise has anything to do with serum creatinine, the measure of kidney function. if so, it makes sense that my muscle breakdown is causing creatinine to rise,and my body weight to rise a bit, too. i may be a little dehydrated, too. i never drink enough. then, even more, the breakdown muscle wouldn't be excreted properly. i know only that creatinine rises the more muscle you have. i don't know about the connection between exercise and muscle breakdown and kidney function. it makes some sense, especially with the weight gain. i can usually lose weight very easily, and i'm just wondering why i'm holding fast or gaining now. if you know, please let meknow! thanks!
