I agree Blackrock. Thanks for setting up this challenge. I will help me stick to my fasting days!
For me, I began my fast after dinner on Sunday at 6:00PM, then fasted all day Monday and ate dinner at 6:00PM on Monday evening, keeping intake under 500 calories. I log what I plan on eating for dinner in the FS food log so I know I will stay below 500 calories. I can't sleep if I'm overly hungry so dinner to dinner works best for me. I lost a little over a pound on my first day of fasting and for me, that's great since I'm not far from my goal weight. If I grazed all day, I know I'd go over 500 calories quickly.
How are others managing their fasting days?
