Indicators of obesity is body fat mass

To understand the definition of obesity Dr. Amp told us that Previously, obesity was considered based on the Body Mass Index (BMI), with overweight people having a BMI of 25 kilograms per square meter or more. And obese people will have a BMI of 30 kilograms per square meter or more. But BMI may not actually be a very accurate tool. In assessing obesity This is because body composition cannot be assessed. For example, people with the same BMI may have different proportions of muscle and fat. For example, bodybuilders have more muscle than people who lack exercise. Therefore, it is not recommended to use BMI alone for diagnosis.

Doctor Amp recommends that Other tools should be used, such as measuring the waist circumference. Because it can indicate the accumulated fat mass. Visceral fat, สมัคร ufabet which is at risk for Metabolic Syndrome. Waist circumference in Asian adult males should not exceed 90 centimeters (36 inches) and Asian female adults Asia should not exceed 80 centimeters (32 inches).

But the best way, Dr. Amp recommends: Body composition measurement using DEXA (Dual-Energy X-ray Absorptiometry) to assess the proportion of total body fat. It is the most accurate method for assessing obesity. In the middle-aged group (ages 20–50 years), women’s body fat should be no more than 32% and men’s should not have more than 28%.

Causes of obesity

People often think of the picture as Obesity is caused by eating too much and not being physically active. But in fact Obesity comes from a combination of many causes. whether it is poor sleep abnormal hormonal function Taking certain medicines to various genetic codes. All of this affects the body’s energy metabolism and hunger and satiety control system.

Hormonal causes

One cause of obesity is an imbalance in the body’s control of hunger and satiety. which is controlled by the nervous system and endocrine glands (Neuroendocrine) where the endocrine glands create hormones that send signals to the brain to tell whether we should continue eating or not. 

Important hormones are The hormone leptin (Leptin) makes body fat mass the body feel full. This hormone is secreted from fat cells. If we don’t get enough sleep, the secretion of the hormone leptin will decrease. The desire to eat will increase. In people who are obese, they have leptin resistance, meaning the body does not respond to leptin’s satiety signal. makes you not feel full And don’t stop eating.

The hormones that work in opposite ways are Ghrelin, or hunger-stimulating hormone Will secrete a lot before meals. and will decrease when starting to eat in people who are obese The secretion of the hormone ghrelin is abnormal. Even after eating, ghrelin levels did not decrease. Makes the appetite not decrease

Genetic causes

Many times it is found that if an adult in the family is obese. Offspring are often obese as well. By the genetic code involved in obesity such as MC4R, POMC, FTO or Fat Mass and Obesity-Associated Gene, etc. 

However, Dr. Amp emphasizes that The body fat mass genetic code is not the only cause of obesity. The more important factor is Lifestyle behaviors, such as eating patterns within the family, such as having a full table of food at every meal or the amount of food per plate is too large and the nature of the food eaten, such as consuming foods and beverages that are high in sugar, high in fat, or processed food groups.
