Guys. No so great. I didn't do well sticking to the rules. Starting Weight: 100% Ending Weight: 98% Loss: 2% Ending Weight from Jan 1: 98% Loss from Jan 1: 2% Challenges: The biggest challenge was that I wanted to eat every day and I wanted to eat well over the 500 calorie goal. I would fast all day, then eat after work and I would overeat because I was starving. I was more successful on days when I spread the calories out during the day. I didn't track calories on the fasting days as I was supposed to. Successes: 2% is something, right? I did find that, at least, it made me think about what and how I was eating. Verdict: Not worth the effort even though the effort is pretty minimal.
