Obesity is mainly caused by the accumulation of excess fat in the body, and it can also be caused by diseases such as Cushing syndrome, which is called secondary obesity in medicine. This obesity can often be improved with the control of the primary disease. But at present, obesity caused by improper diet and reduced exercise is more common in the world, which is called primary obesity or simple obesity. We can use the following formula to judge whether we are obese or not:
Obesity = (actual weight-standard weight)/standard weight × 100%
Standard weight (kg) = (height cm- 100) × 0.92.
At present, domestic experts generally believe that obesity over 20% is considered as a sign. For example, for a person with a height of 170cm and a weight of 80kg, the standard weight should be (170-100) × 0.92 = 64.4kg, and his obesity should be (80-64.4).
Obesity can lead to many diseases. Besides hypertension, diabetes, dyslipidemia, coronary heart disease and gout, it can also increase the incidence of colorectal cancer and breast cancer. In fact, obesity may occur at all ages of life. Once obesity occurs, it can cause the above diseases and endanger health. Therefore, we believe that even after the age of 50, we still need to prevent the invasion of obesity and safeguard our health.
So how should people over 50 prevent obesity? Adjusting the diet structure and controlling the intake of fat as much as possible is the best policy. In addition, long-term adherence to appropriate physical exercise is also an effective way to prevent obesity.
For obese people, different low-calorie diets should be given according to their obesity degree, and exercise should be strengthened to lose weight. If the above basic treatment fails to achieve the goal of losing weight and obesity is serious, you can use drugs to lose weight for a short time on the basis of paying attention to controlling adverse reactions. In addition, surgery can also be performed to lose weight, but it is only suitable for patients with intractable extreme obesity (obesity > 70%) who are ineffective in basic and drug treatment. These patients are often accompanied by respiratory sleep apnea, cardiomyopathy and other related diseases.
It should be noted that although losing weight after the age of 50 has certain benefits for prolonging life, you must be cautious in losing weight. Control fat intake but not completely, and strengthen physical exercise without excessive exercise. Especially when carrying out drugs and surgery to lose weight, you should consult the relevant doctors carefully to be foolproof.
