Not a male but maybe you’ll find that information useful:
If you want to do weekly rolling fasts, make sure that your refeeds are healthy, eating junk while doing that type of routine will bite you in the ass.Of course, you won’t lose the same amount of weight on every fast, it depends on a lot of things like for example refeeds, carb intake, water retention, sleep, exercise etc. But trust the process, don’t worry about small stuff. If you are not eating you are losing body fat. Also, don’t neglect your electrolytes.
