Kissing someone for one minute burns about 2 calories.

The answer is true because kissing involves physical movement and can be considered a mild form of exercise. During a passionate kiss, the body engages in various muscular movements, including the facial muscles, neck muscles, and even some core muscles. These movements increase the heart rate and slightly raise the metabolic rate, leading to a slight calorie burn. While kissing for just one minute may not have a significant impact on overall calorie expenditure, it does contribute to the overall energy expenditure of the body.
