First of all, the human body normally needs to consume at least 1500 calories every day.
So the heat consumed by ordinary exercise is:
Walking slowly (4 kilometers per hour) 255 calories
Walk fast (8 kilometers per hour) 555 calories
Jogging (9 kilometers per hour) 655 calories
Running (per hour12km) is 700 calories.
Bike (9 kilometers per hour) 245 calories
Bicycle (16 km/h) 4 15 card
Bicycle (2 1 km/h) 655 cards
So walking for two hours consumes 1 1 10 cards.
The calories consumed by a normal diet plus walking for two hours are:
1500-11/kloc-0 = 960 cards
Besides,
1 pound of fat equals 3500 calories, and 1 kg equals 2.2 pounds.
So 1 kg fat equals 77 16 calories.
Then in theory, it takes about 8 days to lose one kilogram.
But I don't advise you to exercise without eating.
Because losing weight is actually a metabolic activity of the body, if you exercise more than the calories you absorb, you will naturally lose weight. Furthermore, losing weight without eating is easy to form yoyo phenomenon, that is, it has the effect of losing weight in a short time. Once eating is resumed, the weight gain will be more terrible than before.
If you don't advocate skipping meals when you lose weight, you won't lose weight because:
First, the human body has the function of self-protection. When you eat little calories (that is, food you usually eat) or don't eat calories, the human body will reduce its metabolism in order to maintain normal activities, so if you don't eat crazy exercise, it will not only be bad for your health but also fail to lose weight.
Second, when you have healthy food to maintain the functioning of your body and add it to exercise, your metabolism will improve and the effect of losing weight will naturally occur.
So I hope you can exercise regularly for 3 to 4 days a week under the condition of normal and healthy diet.
Sitting and stretching often can improve metabolism and keep you comfortable. After all, losing weight is a woman's lifelong career, so don't be too impatient.
Finally, I wish you an early success in losing weight.
