Thanks liftinlady

I'm actually doing much less cardio than 'normal' what is different though is the intensity, and the added weights.

I have done all the reading on HITT, but you know I'm not sold on it. I don't know yet. My logic tells me that if my sugar levels are low in the AM, because I'm in a fasted state, plus I'm low carb, AND because it usually takes 20 minutes of burning sugar to get to your fat, that my body will take muscle in the absence of glycogen.

I've read through the debate on the other threads on this. Lots of controversy. I think the bulk of the research has been done on people that are not eating LC.

Thanks for the advice though, I'll take it slower and see when I plateau to add more cardio. This is week 3 for me, and normally this is when I plateau. I haven't lost any weight since I weighed in last Friday. I tend to have to work harder than other people to keep the weight loss up, probably the thyroid problem I have...

Thanks liftinlady, advice appreciated as always.
