However, for China people, our standards have been slightly revised. If the BMI exceeds 24, you will be overweight, and if it exceeds 28, you will be obese. For example, an adult with a height of 170cm will be overweight if he weighs more than 138kg, and obese if he weighs more than 1, 6 1. This standard has also been widely publicized and popularized.
It is easy to cause abdominal obesity in East Asians, which means that we have an apple-shaped figure, which is also very harmful. Therefore, in addition to body mass index, we should also pay attention to our waistline. Adults, the waist circumference of boys below 85 cm is normal, and that of girls below 80 cm is normal.
BMI is calculated by dividing your weight by the square of your height.
You might as well use this body mass index to calculate whether you are obese or not.

About energy
Next, we use the great law of conservation of energy to analyze weight.
In the first case, if the energy intake is greater than the energy output, then the weight will increase.
In the second case, if energy intake equals talking, then the weight is balanced.
In the third case, if the energy intake is less than the energy output, then the weight will drop.
Energy intake mainly comes from the digestion and absorption of food, such as eggs, rice, chickens, ducks and fish.
There are three main aspects of output:
The first is to maintain one's own metabolism, including blood circulation, body temperature, growth and repair.
The second is to do some housework and play ball games.
The third one is a little hard to understand, in fact, it is the energy we consume when eating.
In terms of energy intake, we actually have a conversion rate (the ability to absorb energy)
Calculation formula of weight change
Finally, according to the analysis, we will get a formula to calculate the weight change.
Weight change = (energy of food * ability to absorb energy)-(metabolic consumption+exercise consumption energy+food consumption process)
Weight change = (energy of food * ability to absorb energy)-(metabolic consumption+exercise consumption energy+food consumption process)
From the formula, we know that in order to lose weight, we can consider it from five aspects.
From the formula, we know that in order to lose weight, we can consider it from five aspects.
1. Reduce the total energy of food.
1. Reduce the total energy of food.
2. Reduce the ability to absorb food energy
2. Reduce the ability to absorb food energy
3. Enhance the consumption of metabolism
3. Enhance the consumption of metabolism
4. Enhance sports consumption.
4. Enhance sports consumption.
5. Increase energy consumption when eating food.
5. Increase energy consumption when eating food.
Of these five points, the last one can exclude the energy consumption when eating food, because research shows that the energy consumption when eating food has a linear relationship with the energy of the food itself, that is, eating two steamed buns consumes twice as much energy as eating one steamed bun, which is easy to understand. At the same time, considering that the energy consumed when eating food is still very low, we know that the weight loss treatment method has not taken this aspect into account.
The fourth thing that will increase energy consumption in sports activities is to exercise more and stretch your legs.
The first three therapies to help us lose weight
Many people go for weight-loss surgery. The real purpose of weight loss surgery is to make the stomach smaller and the small intestine shorter, so that people eat less and the body's ability to absorb energy is reduced. It's that simple.
Then the diet pills that everyone is taking now also achieve the purpose of losing weight from the perspective of reducing food energy intake and energy absorption.
If we use these diet pills again, it will only make people say that they have 3% to 5% weight, and our instinct is to "eat food". If we just don't eat, it will go against our instinct of "eating", but after a while, we will be very hungry, leading to eating a lot, then regretting not eating, then getting hungry and eating a lot, and entering this endless cycle.
In fact, the third item, increasing energy consumption in metabolism, sounds easy to achieve the purpose of losing weight.
But in fact, the human body is engaged in metabolism, including maintaining body temperature, promoting blood circulation, helping tissue growth and repair and other basic functions. These are all precise adjustments made by the human body itself, but they are difficult to control.
However, it is found that there is something called brown fat in human body, and its function is to carry out high-intensity metabolism and consume energy. I found some kind of slimming drug, which can stimulate brown fat, improve human metabolism and consume energy, but it has some side effects and also regulates urination activities.
Remember the weight change formula.
Weight change = (energy of food * ability to absorb energy)-(metabolic consumption+exercise consumption energy+food consumption energy)
If you are brave, do weight-loss surgery directly (because considering surgery is risky). If you are timid, take your time, take some diet pills, pay attention to diet and exercise more, and you will lose weight in the long run (and develop good living habits).
