I have been doing this for a while now during the week. Call it skipping breakfast or whatever, but you’re taking a meal out of the equation. I stop eating at 7. I don’t really restrict calories, as I bet I down 5,000 easily on a Saturday with beer and whatever else I eat.
I literally just came off a 66 hour fast today at noon. Hadn’t eaten since 6 o’clock Sunday. Water and black coffee in the morning. It’s amazing how much water weight you can drop. I was 251 on Saturday and 241 this morning. I do this once a quarter.
