Multivitamin if you think you may be malnourished. Don't skip breakfast.
For breakfast, look for protein & fat. (Bacon & eggs). With butter. A small amount of carbs is okay, but watch the toast (grains) & jam (refined sugar). Tea/Coffee with cream, if you like. The protein and fat will help with satiety and avoid a big carb/sugar insulun spike.
I wouldn't bother with genetic testing or obscure supplements until you feel like you have the basics covered, and have found a lean, stable body weight.
If my anecdote can counter your (healthy) skepticism, I ran the "who needs breakfast?" experiment on myself as a high schooler. I regret it. I was constantly dizzy/lethargic in the morning, despite eating well in the rest of the day. (Of course, you can point to the differences between a teenager and an adult person.)
I have the opposite anecdote: If I ate breakfast, I was tired/lethargic/falling asleep until the afternoon - but if I skipped breakfast, I was alert and awake until dinner time.
