Generally speaking, consuming 1200 calories can make you lose a catty, but it doesn't count when you lose weight. Because it is difficult for a person to consume so many calories in a short time.

People normally consume about 2000 calories a day, while jogging for half an hour consumes about 120- 130 calories. Under normal circumstances, people will consume about 1000 calories when they don't move for a day, and 1800+ when they work normally. So if you burn 180 calories, you can't lose weight, but if you keep exercising every day and burn 180 calories every day, you can lose weight slowly.

Cal (card for short), transliterated from English Calorie, is defined as the heat required to raise 1 gram of water to 1 degree Celsius at 1 atmospheric pressure.
