Is there a way to tweak needs like hunger and sleep?

My sims like to eat, sleep, shower, etc when these categories are half met.  That means I have to constantly stop them from cooking Mac and cheese in their cauldron (or get them to finish their plate early and save the rest as leftovers, otherwise they’ll start getting fat.)  And one of my sims is like “I’m just starting to feel tired and the new neighbor just now agreed to woohoo with me for the first time, but I’m going to sleep now”

Besides turning free-will off, is there a way to get them to head to the fridge when their stomachs are less full?
