The diet spread by vets and the rabbit house society has zero science behind it. In fact this diet can cause lots of problems for rabbits including but not limited to; urinary calculi (kidney stones and urinary stones), malnutrition, diarrhea, ect. We highly recommend proper feeding of a commercial rabbit pellet. This means feeding food that smells fresh and wasn't manufactured more then 3 months ago, feeding the proper amount for your rabbit, and feeding a quality rabbit pellet with no seeds or bright colors. a 16% pellet with the first ingredient being hay is ideal.
