Multiply the weight by 24 the energy that this person needs in a day, for example.
68kg*24= 1632
Daily physical activity momentum is multiplied by 1.2.
Heavy physical activity multiplied by 1.5
1632 * 1.5 = 2448 kcal
The amount of weight loss in a week should be controlled at around 1 kg, which means that 7000 kilocalories will be consumed. Therefore, it needs to consume 1000 kilocalories every day. The diet is controlled at 2000 kilocalories per day, plus 600 kilocalories.
(the speed of 7.0km/h is about one hour), and you can lose one kilogram every week.
