All I know is that my endurance (as to running) immediately dropped after starting Atkins. I wasn't expecting it, and didn't think about the carb connection until later, so it wasn't something that was in my head.

I began Atkins on a Friday (after regular 5-mile run). On Sunday, I ran in a 5K. Usually, from pushing too hard, I would start to feel it in my lungs. But, this time, I felt it in my legs. They just felt like they didn't have the strength to go on - it was realy weird. Halfway thru, I had to start taking walking breaks.

For the next few weeks, I could barely run 3 miles. I kept at it tho. Eventually, my endurance came back. About 3-4 weeks in, I just was able to run 4-6 miles again. My pace as dropped dramatically.

We are specifically talking about endurance. I don't think the low carb has affect on strength and energy. Only on going for the long haul.

I personally feel that I will do better when I'm able to get more carbs again. Induction level is definately low.
