Ackies, as well as other odatriad monitors should eat everyday, given the proper temperature levels are met in order to allow them to properly metabolize their meals.
LOW TEMPS = OBESE MONITOR
Just look at all the sav's and salvators that are kept at room temp, they become morbidly obese.
I prefer to feed my monitors some variety in their diet. With the expensive costs of feeding monitors, I decided to start with a clean slate and breed my own feeders. It is fairly simple, inexpensive, and easily accessible(no frequent trips to the pet store). I raise superworms, mealworms, waxworms,and cockroaches, and am trying to find a supply of trevo worms(butterworms), however there is absolutely no info on their care and breeding.
I usually try to feed a different prey everyday, with waxworms being only a snack once every other week. Mealworms and Crickets are fed most frequently, followed by supers and cockroaches. I dust my feeders every three days with supplementation.
Hope this helps, let me know if there's anything else I can help with.
