question. when you're out hiking do you constantly take snack breaks?

whenever i watch american youtubers they take a snack break every 40 minutes it seems regardless if they are hungry or not. i'll do 20km and not feel famished enough for a "snack" until i'm able to eat the real food i packed.

snackpackers what we think??? is it a meme to take 3 bites off an oversized cookie then keep walking or what
