This is probably better placed in the diet/nutrition thread, but I figured I'd come here first. I've been doing the NROL4W since January (a week behind the official challengers) and have seen nice strength gains so far and am pretty impressed with that aspect of things. However, I don't feel like I'm losing much fat around my new-found muscle. The way of eating that is outlined in the book is very close to what I've always done, though I had to work on getting more protein in and watching my grainy carbs. I had been eating between 1900 and 2200 cals which is right near maintainance for me. I tried dropping a few cals to around 1800 to 2000 cals and didn't see a change. I see a lot of talk on here about carb-cycling, and cutting and all that stuff and I'd like to try it but I'm unsure how to go about it. I don't have a lot of fat to lose, but I'd like to lose it before summer (aka bikini season) hits. I don't want it to hinder the strength progress I've made though. Right now I'm basically doing the NROL4W workouts on MWF, with rest days in-between. Maybe I should keep eating the way I've been eating but add HIIT on T,TH? Or do a "cutting" type eating plan for a while?
Any ideas, suggestions, helpful hints to get me started?
Thanks!
