I'm been doing fast days for a couple months now, but it actually seems to be harder now rather than easier.I'm fasting today (after gaining nearly 5 pounds on two consecutive eating days) and so far doing okay but it's not as easy as it was a couple months ago when I started it. I'm toying with the idea of the Fat Fast too which I find more appealing that Longo's FMD. But then again veganism doesn't appeal to me at all.
