Wanting to start as a trucker

Hello everyone let me get my stats out of the way first

Age:27M

Height: 6'1

Weight:370

Job:otr truck driver

With all of that out of the way I am looking for advice. I want to start this diet. I've seen some pretty crazy results online and with a friend who has been on this diet for 2 years. Before I became a truck driver I lost 40 pounds. At that time I was 380 then dropped to 340 just by working out and counting calories. That was when I had free time and could go to the gym everyday. My question is what all can I eat really? Like I know meat fats and dairy but what about nuts? Also how do you guys deal with fiber? I'm assuming just eating straight protein will make shitting impossible? is milk ok to drink or do you stick with just water and black coffee. What would be some easy recipes for me since I'm in a truck. I can get an electric skillet for sure. I'll probably get a mini crockpot also. What are some good snacks? I know pork rinds are a thing but what are some other good options? Do I need to watch portions? I can eat a fuck ton if I really want to. If I made it a mission I bet I could eat a whole dozen of eggs. If any other truckers are on here advice would be appreciated.
