I'm sorry if this is a common noob post, but I'm starting a IF plan, and I'm having trouble figuring out how to do it logistically. Any IF that can give me some guidance?

37 male 230 lbs, goal is to get to 180 lbs

I work most days from 9-6

I've been trying to stick to 7-17 from 1 to 8, but that often makes it so I miss a chance to eat lunch at work, and then end up binging on junk when I get out of work. I tried a 8-3p, but I always ended breaking it when I go out with friends.

1. People that do OMAD, where do you usually stick it?
   
2. And do you end up changing your foods a lot, or just eat what you like in that time?
   
3. And how do you find energy to workout? I've been trying to orde premade meal plans, but they're all based on low-calorie diets, so they don't fill me up when I eating 1-2 meals a day!
   
4. Lastly, do people in their 30-40s find this harder than people in their 20s?

I really appreciate having this community, and am impressed with all of your effort and willpower! This is probably the last time I can get excited to try something. If this doesn't work, I may just learn to accept being a fatty, lol.
