That's interesting.The 16/8 is pretty standard, try bumping it up to an 18/6 (three medium meals 2.5 hours apart) or even a 20/4 (2 meals 3 hours apart). You can drink water or herbal powders throughout the fasted state but nothing that would spike your insulin levels, and no caloric content. The lifts, runs, and moods are a lot stronger when you're on the fast. Remember your essential vitamins, minerals, and nutrients, if you give your body everything it needs then you will not become hungry during the fasted states. When your body is not digesting food all the time the blood will be free to move around to your brain and your muscles, and you can busy them with learning and exercise, two things you must keep up at all costs.
That's good to know, thanks. I plant to drink lots of water to make my stomach feel full.I once fasted for 7 days. It wasn't for spiritual reasons, but because I had very bad gastrointestinal problems. I can honestly say that I was not hungry the whole time, but then I wasn't eating much before the fast and was probably borderline keto. After a day your body will start burning fat for fuel and hunger usually disappears once in ketosis.
