Congratulations! It is a great workout, there is no doubt. One thing I have noticed, though, as I have also lost quite a bit of weight, is that I now have this ability to eat virtually anything at any time and still not gain weight. This is encouraging me to eat badly more often than I would like as the little voice inside me keeps saying: "Go for it. You're not going to gain an ounce."
It seems counterintuitive, but it is something I have had to really keep an eye on. That ability to easily keep off the weight can at times be a bit of a headache.
