I've done varying levels of carbs and I personally hated VLC. It did nothing for me but make me miserable the entire time. I now do 70-150g of carbs a day and am much happier. I lost the initial 3-5lbs of glycogen-water weight and gained it back when I added carbs in again, but after less thank a week my weight stabilized. I did notice my belly seemed bloated but that only lasted for about 3 days after adding in more carbs.
I am pretty active (waitress walking at least 4miles a day and workouts 6days a week) & I noticed nothing but major drops in my athletic performance, energy, mood, etc when I was doing VLC. I struggled to work-out, let alone complete my resistance work-outs. Had enough one day and I ate about 150g of carbs. Immediately felt awesome & the next day went for a 6mile run.
I'm happy that I tried VLC just for the fact that I now know my body does not like it. My carbs are mainly berries, broccoli, sweet potato or white potato, onions, lettuce, tomato, peppers, carrots, occasional apples or bananas. I feel I've been having more cravings for ice cream since going VLC, not really sure why that is but the cravings have been quite strong!?
Not sure about the carb intolerance but I've been reading from Robb Wolf and others that VLC long-term might not be the best so it makes me feel better about adding in more carbs. Of course, LC works great for some, to each their own! I would certainly think that with how active you are, adding some carbs back in would be a great idea-try it for a week or two?
