Oh, and learning to cook meat/protein so it is tender, browned, flavorful, and seasoned properly. It also seems like acid is way under-utilized in a lot of lazy / American style cooking. Helps a lot with palatability and digestion to use lime juice, rice vinegar, and other acidic ingredients during the cooking process.
Eat more veggies, too. They are full of digestive enzymes, but most veggies don't add too many calories.
Thats a pretty big meal but if you split it in two and have 8 hours between them it's really not that much. Doesnt seem like it should be a problem.
I'm 60kg, 1m83, with I guess strong and endurant muscle with all the bike and manual tasks I'm doing
But yeah, even the minimum is a lot, and it’s hard to achieve without building all your meals around protein.
