Okay, that makes sense. My concern with the effect on LBM was that it would eventually have a neg impact on the workouts. I tried 50 the other day just to see what it would feel like - you are a woman of iron constitution....everything was fine til about 9pm when I had a total meltdown and went for my daughters valentine's day candy, I got a grip after a handfull of m&m's. Note to self: eliminate all candy from house on low carb days.
I think I would do fine at 100 on the low end while adding mass. I don't have competitve aspirations so 12-14% bodyfat would be fine with me.
