Default Training and diet with kidney damage

Hi all,

I'm concerned about a friend of mine. (No, not me this time, thank God.)

She's in her early twenties and about 2 years ago she lost one of her kidneys in a car crash. The other one is also slightly damaged and not functioning at 100%. She recovered well and is an exceptional athlete, no question about it - very strong, lots of muscle mass, great work capacity. Bodyfat is a bit high, but because of her kidney damage, she's wary of any diet that is too high in protein. So far the only recommendation her doctor has given her is to stay away from protein supplements and cut back on salt.

I read up a bit on diets for people with kidney problems, but the recommendations seem to come from the same place as the low-fat, high-carb, margarine-is-better-than-butter recs and I don't know enough physiology to sift out the good info... Maybe someone more knowledgeable can point me to some reading material or suggest some guidelines to help her stay healthy in the long run (first of all) and possibly lose some bodyfat?

What about training? She is a dancer and besides that she lifts heavy once or twice a week and does a good deal of handbalancing, pressing etc. (ex-gymnast). That seems to be working well for her. I'm thinking the only thing she should be mindful of is not doing any really long metcons (risk of rhabdo) - input on this?

Many many thanks in advance.

Limiting phosphorous intake is important as well.

Rhabdo would probably be the end of the world...

No long metcons, no metcons with exercises that are not a staple in her regular rotations.

Finding some form of bicarbonate (probably potassium instead of sodium) and having her take that on a regular basis would be helpful.

Thanks, Brandon and Dr. G. I'll pass on the recommendations.

Seriously, a nephrologist would be a little more helpful here than Teh Internetz.

Depends on how her kidney is functioning

Of course she is seeing a nephrologist. Like I said above, the only advice he gave her was not to go too high on protein and stay away from protein supplements, to cut back on salt, and carry on with her physical activities, all of which she is doing. That may be enough for 99% of kidney patients but I doubt most nephrologists know how to deal with someone who is an outlier in terms of athletics and diet.

Granted. So someone specializing in such patients might be better. But the point is: the kidneys do not fuck around, and in turn should not be fucked with; the very last thing you want is to find yourself going to dialysis three times a week. Trust me.

Although I don't have it myself polycystic kidney disease runs in my family and the advice we've all been given is to eat a regular healthy diet with plenty of fruit and vegetables and not too much animal protein.

As far as athletic performance goes protein requirements will be met automatically on almost any mixed diet if your calorie intake is adequate so it's unusual for anyone who isn't dieting to actually need supplements. It's worth noting also that carbohydrates have a significant protein sparing effect and this may be an important consideration for anyone needing to restrict their protein intake for whatever reason.
