24 hr fasting would be eating once a day at the same time - so for example 7pm every day. This is also known as OMAD or one meal a day.
Alternate day fasting would be eat nothing Monday - eat anything you want on Tuesday, eat nothing Wednesday, eat anything you want Thursday and so on
48 hr fasting would be for example eat at 7pm Monday, nothing Tuesday, 7pm Wednesday, nothing Thursday 7pm
I’m not recommending to you or anyone else these ways of fasting just explaining time frames etc.
also the times you do eat on any type of intermittent fasting should be dense in calories & nutrients to sustain your health, it’s important that the food you do eat is nutritious
Is it safe for you to eat like this
@cdpm considering you are on insulin?
