We're planning a 9 to 10 hour dive. We can't go that long without eating.
What kind of 'food' could replace at least 2 meals of the day so we can 'survive' a long dive like that?
We'll figure out if something can be eaten while scuba diving. But maybe someone has already done something like that or has another 'extreme' sport where normal food isn't applicable anymore.
I'm thinking astronaut food but where do you get that?
I'm looking for something that looks like tube of toothpaste or similar.
