Remember when Snickers taught the world that grown men turn into Betty White when they're super hungry? While you may not transform into a Golden Girl on the gridiron when you're famished, you may feel like punching something — and now there's scientific evidence to legitimize your "hangry" behavior.
A June 2018 study published by the American Psychological Association in the journal Emotion found that two key things determine if hunger will contribute to negative emotions: context and self-awareness. For two online experiments in the study, researchers showed more than 400 participants an image meant to induce either positive, neutral or negative feelings. Subjects were then shown an ambiguous image (a Chinese pictograph) and asked to rate its pleasantness on a seven-point scale and report how hungry they felt.
