Trish, I do IF for around 24 to 26hrs. Then break fast for anything up to about 3hrs. But this rarely happens. Maybe eat for 45mins most times. Do not really count calories but I find what I eat makes me full on less food. I generally will eat around 2 to 3pm. Not unless I have a dinner to attend later in the night. Then I will extend my fast accordingly. Baz😀
