Hi this is Dr. Hill. When a rabbit is not producing stool it is usually a sign that the intestines are not moving ingesta through properly (gut stasis). This can be very serious in a rabbit. The majority of his diet should be hay, at least 80%. By regular food, do you mean pellets? How is he acting otherwise? Is he as active?
I recommend syringe feeding critical care herbivore. Is there a local veterinarian who works on rabbits? It would be worth having him checked and started on the critical care, potentially pain meds, fluids and a motility promoting drug called reglan. Is it possible he could have chewed on anything?
