If you can drink enough water, you can consume a bit more protein (not too much more; up to 60-65g is ok. More is not helpful and is wasted, unless you're training for the Olympics) without problems. Generally, taking more creatine won't help....it gets digested, and is no different than any other (much cheaper) protein. The issue is that the amount of water you need to drink to markedly reduce kidney stone formation is a lot...at least 2.5 liters a day. Most people don't manage to make it to 2 liters a day unless they force themselves to drink more water. It helps if you add a bit of flavoring (e.g lemon flavor) to it. Especially if you exercise a lot, you will need to drink even more. How much more? If your urine is totally colorless (not yellow), you're drinking enough. You can do your weight training and eat a bit more protein with no problem, but generally, one will not see any additional muscle increase by eating much more protein (more than 60 g or 65g per day). So eating 100 g of protein per day will not increase your muscle mass, and will increase the risk of kidney stones. All the protein whey powder and creatine are more psychological...you can get the same benefits by eating a couple of extra egg whites per day.
Kidney stones training nutrition adviceThree weeks ago I've got my first kidney stone experience, and it wasn't pleasant. I just expelled it recently and went back to the hospital to do one more check up and also to give the stone to them in order to determine what kind of stone it is... After the check up they told me the stone went out and I was ok. But apparently I have another small one forming in my other kidney. They said it's small and even if it started moving I'll probably just expel it without any problems or pain, but I need to be careful on not making it grow bigger so I should drink plenty of water. So far so good.Now my problem is; I'm underweight and I've got a sedentary job, and I'm starting an intensive six months program at the gym to build muscle mass. This program include a very strict diet plan and the consumption of protein whey powder and creatine. I read in many forums that protein powder and creatine are not ideal for subjects with kidney stones history. And when I asked the doctor after my check up he just said "doesn't matter what you eat, just drink a lot of water". Now, I'm not an expert, but I do believe that what you eat does matter...I'm asking for advice here because I cannot see a specialist at the moment. I was wondering if taking protein powder and creatine wont have any negative effect on the formation of other stones as long as I drink plenty of water, or if I should avoid them...And if I should avoid them, are there any substitutes I can take?To give some context. I'm male, 32 years old, 187 cm and 69 kilos, never had kidney stones before, never took creatine before, I took some protein whey powder for about 40 days one year ago. I'm not under medications. I don't have any history of diseases.Any advice is really much appreciated.
