Preferably something that has little to no preparation required.
Banana. If still hungry then apple. If still hungry then banana. Repeat.
Fruits are good for you. Sugar in the morning and they hydrate you aswell. Might be a good idea to have a sandwich or something as a snack before lunch.
Op was asking for a fast breakfast really early in the morning. I think its not a good idea to eat something very heavy just after waking up. That’s why i recommended a sandwich as a snack some time later before lunch.
Fast as in the non-eating time since last meal or fast as in quick? I might have missed the original question… If it’s the latter, there’s plenty of quick, filling meal items in the morning. When I was serious about weight lifting, I would drink a protein shake 1-3 times a day to supplement muscle-building.
As for the former, intermittent fast-ers are adamant that anything other than water, plain coffee/tea will break their fast and provide less benefits.
I don’t know, but wonder if there is a scientific basis for this. If you’re avoiding eating something that’s going to fill you up (ie protein), my reaction is kind of “why bother”…
