Personally, in RL, when I'm hungry and my sugar is low, I'll easily wander off task/meal making.

When it happens, it takes a
guiding hand in my house (like my dad or sister) to help me get back on track and fix something to eat.

So if my peep is wandering off from his/her meal preparing, I'll check through the household for the peep with the greatest energy level (just a personal preference, not sure if it has any effect on the outcome), and start the meal again.

Sometimes, I'll praise that peep to keep him/her going. But mostly, I only praise them for preparing a meal when preparer is low enough on the Fed meter.
