Not necessarily, many small animals have an utterly insane metabolism making them eat their entire body mass in a couple of days. For example, hummingbirds eat the human equivalent of 150,000 calories per day.
Larger animals typically cannot afford to spend so much energy - there is just no large food source that has sufficient calory density.

Good point! I’d love to see a by-genus breakdown of average metabolic rate vs body mass.
