Disclaimer: Intermittent fasting is considered a controversial topic by some AND depending on your health may not be a good idea- so you are responsible for checking with your doctor or medical professional before doing this. I am not a medical professional and the following are just my opinions based on my own experience and the research that I've done. There are quite a few books that expound on both the history and proof of the efficacy of fasting and I firmly believe in it's use, when done the right way, myself.
When You Have A Choice- Picking Your Fast Day
When you're in phase 3, ideally you want to catch major gains as quickly as you can and fast immediately. It just seems to work better this way. Once you let weight "lie around" on ya for a bit, it seems like it wants to stick to ya more. ;0
That said, once you are in Phase 4, you want to balance seeing the need to fast with what your week's schedule looks like. Some days are just going to be mentally/emotionally inordinately hard to fast, and in these cases, it seems like the strain and the potential of not being able to carry it out isn't worth choosing to do a fast on a difficult day.
So if you have a luncheon planned with your in-laws on a Wednesday, and you have a full day of work on Thursday- me personally, I would choose Thursday to fast because not eating at the luncheon will be super hard, and when I am working, the day FLIES by and the fast day happens almost without thought. So even if I notice on Tuesday that my weight is higher than normal, while I might try to eat a little cleaner on Wednesday- say after the luncheon eat lean chicken breast and a phase 3 smoothie for dinner or something, but I will PLAN to do a fast day on Thursday when it's going to go fast and feel much easier.
