The Science of Fasting

I was back up to 260 this morning after staying around 248 for several of months towards the end of last year. Even went as low as 242 for a couple of days after a 40 hour fast. I woke up this morning with the intention of doing a two day fast (approximately 44 hours). I have been struggling to even hit my usual 18/6 or 20/4 fasts that I was doing effortlessly last year. If I can pull this off, I hope it will jump start me back to my consistent fasts and weight loss. So far I'm resisting the lunch temptation. I definitely feel, and see, the added weight.
