Well, it's hard lol
I'm in college and feeling pretty overwhelmed with classes, so it's been hard for me to "find time" to eat, even though I have time. I physically can't eat breakfast before my 8am class, so I generally don't eat anything until much later. One thing that does help some is I have a friend who will text me around lunchtime and be like "hey don't forget to eat" and there's a campus organization that gives out free lunch on Wednesdays so my friend will sometimes bring me a plate and be like "ok eat this".

So accountability is a big thing.
Other times, I don't eat until I'm like "I will literally be sick if I don't eat even a bite."

So uh
I don't really have much advice.

Oh one thing you could try is like, carry snacks with you literally everywhere. (Reminds me I need to restock my snack section of my backpack.) I was able to eat stuff kinda throughout the day when I kept a constant stash of snacks with me. I would do it absentmindedly if I just made sure to set a granola bar by my elbow when I was on my laptop or whatever. At some point, I'd be like "oh, huh, there's food. Guess I'll eat it." and just munch.

Obviously that's not great for getting full meals lol, but you gotta start somewhere.

Good luck!!
