Carbs and Fat

[Catrin]

90 to 130 is a big range. 90 wouldn't be enough for me on the training schedule you're keeping. My understanding is it's only hard on your kidneys if you're not using the amino acids to build or repair muscle. But I'll defer to those with more knowledge of the subject.

Personally I prefer the 130, the dietician wanted me to pull it back to 90 (some formula related to my weight). I've not been really successful with that so it is more like 110-130. Considering the kind of workouts we've had in class, it may well be that I needed 130 on those days.

The class is over for now, there will be a similar class starting in June that I will likely take - hopefully with the same instructor - he has quite the no-nonsense approach that I like. It ensures I get off the bike at least two days of the week and at $15 it is certainly affordable for a member. They have a couple of high intensity free classes that I will check out between now and then.

Our trainer is helping me change my usual workout to incorporate elements of the metabolic training into my usual fitness library so, for at least the next month, my training will be a combination of the old routine and elements of the new - with increasing riding if it ever should stop raining and warm up.

Added: I've been doing some reading, and there appears to be several studied opinions out there about the best amount of protein if you are working to build muscle. It also appears to be a myth that high protein consumption has any effect on the kidneys other than to make them work harder to remove the excess nitrogen - so not harmless but neither does it cause kidney damage. I may stick to her suggested 90 grams on non-metabolic training days and bump it up to one gram per pound of body weight on days I do metabolic training. That might be a good middle ground...
