Kissing someone for one minute burns about 2 calories.

The story behind the answer

True. Gentle kissing engages small facial and postural muscles and slightly elevates heart rate and breathing, so it burns a little energy—roughly 2–3 calories per minute on average. Intensity matters: more passionate kissing can burn a bit more, but it’s still a light activity compared with walking or exercise.

Context helps: most of your daily calorie burn comes from basal metabolism; light activities like kissing add small amounts on top. Kissing also triggers feel-good chemicals (dopamine and oxytocin) and can lower stress hormones, which may make it feel invigorating even if the calorie burn is modest. Memory tip: two lips, two calories—“two-for-a-smooch” is a handy way to remember the rough burn rate.
