I was reading about carb cycling on T-Nation, and it seems to be very popular for fat loss and swift size gain. The funny thing was that every source I could find included grains and such... but I only eat vegetables and a few fruit for my carbs. Poliquin says that vegetables can be eaten in practically any amount you like, though, so I'm not sure if carb cycling can be applied with just greens.
I'm currently doing a bit of fat cycling of 40-50 grams one day and 120-150 the second. I just eat about 100g of carbs a day from greens. It seems to be quite effective, but I'm interested in learning more about why and how the two methods (fat cycling and carb cycling) work. Can anyone put it into layman's terms for me?
