I don’t think I can find it explicitly mentioned anywhere about fasting, hence, a couple of silly questions:
If you fast for multiple days, does that mean you literally eat nothing at all and if you do eat, what do you eat?
If you intermittent fast, do you only eat as much as you would eat in a single meal, or should you eat your daily intake in the single or two meals that you eat? I could easily eat just the breakfast’s worth so about 500kcal, and then eat the next time next day - is this bad?
When I fast I don’t eat anything but may drink coffee with cream and coconut oil, tea with low carb milk or maybe some broth depending on how long the fast is for.
I always do at least a 16:8 fast as I don’t eat breakfast just have hot drinks.
That’s just what I do.
I don’t eat any solid foods. I do use some fat (butter and/or MCT oil, and a small amount of HWC) in my coffee, to get some extra fat in, since I don’t have sufficient body fat to fully provide for my daily energy requirements. See @richard’s post here for more info:
With IF, you will typically consume all of your daily calorie needs in your eating window. So if you need 2000kcal/day, and you’re doing 20/4 IF, you’d eat 2000kcal during your 4 hour eating window.
