Two things make you feel less hungry, longer. And that’s fiber and protein. So what’s something portable like an apple that I could buy a lot of and eat at work or whatever? Like I could buy a lot of apples and eat them anywhere, and while they have fiber they don’t really have protein.
Most kind of seed, like Flaxseed. However eating raw seed is super dry. I try to mix it with low fat yoghurt and/or add a fruit like Dates for a bit of sweetness
