Fussy eaters

[WHYohwhy12]

My kids (7 and 13) are so fussy with food I'm loosing the will. I always make sure there's two foods on their food they like but they still barely eat much other food. I swear my daughter eats two fruits and no veg. Won't eat meat and used to eat cheese but now refuses. Any tips? I've got in the trap of offering them cereal after if they don't eat. Any advice? Tempted to go 80/90s parent mode and if they don't eat it they get nothing else

What does a typical day of meals look like for them, OP?

Are they eating sweets or maybe junk foods before meal time? What are their usual activities before meal time? I had the same issues with my daughter before when they were rioting about eating greens like broccoli and beans, so I tried switching to other veggies that is not green like pumpkin or carrots.
