Generally speaking, people's heart rate is about 70 times per minute, but when kissing, the heart rate can soar to 100- 150 times per minute, which is comparable to aerobic exercise. Converted, a quick kiss can consume at least 2~3 calories per minute, while a romantic French wet kiss can consume at least 6.4 calories per minute. A particularly intense kiss, plus a big "action", will consume more calories.
When we keep the intensity of French kissing, kissing 10 minutes can consume about 64 calories, and kissing for 30 minutes can consume the calories of eating a bowl of rice (about 192 calories). There are conditions for losing weight, provided that you can't eat seaweed indiscriminately while you have a kissing partner.
The calorie of an egg is about 64 calories. You can't just eat one egg a day, can you? If you want to lose weight by kissing, it takes about 7700 calories to lose 1kg of pure fat. Suppose we kiss for 30 minutes every day and consume 192 calories every day. How long does it take to lose 1kg fat? 7700- 192 ≈ 40 days
In other words, it takes at least 30 minutes to kiss every day to burn off calories, and it takes 40 days. By then, your lips must have been numb. Although the heart rate is high when kissing, it can only play an auxiliary role at most. If you don't control your calorie intake, it's still a little difficult to lose weight by kissing!
