Jayapataka Swami: You see you can eat as much as you do service. If you do a lot of service, a lot of physical work for Krsna, you can eat more! If you do like office work, you don’t do much physical exertion, then it is not good to eat a lot! I may speak more. Usually Srila Prabhupada advised people to eat light at night so that they can get up early and have a sound sleep. So we take a large, a good breakfast, a good lunch and eat a little light at night. Hare Krsna!
