Obesity is a metabolic disease that occurs when the caloric intake of the human body exceeds the calories burned. The surplus calories are stored in the body as fat. When the amount of accumulated fat exceeds the normal physiological needs and reaches a certain level, it develops into obesity. Therefore, obesity is the manifestation of excess calories stored as fat in the body. There are many methods to assess obesity, with the Body Mass Index (BMI) being one of the most common. The formula for calculating BMI is weight divided by height squared. In China, a BMI of 28 or greater is generally considered obese.

What should people with obesity not eat?

Patients with obesity generally also have elevated blood lipids, elevated blood uric acid, and slightly high blood sugar. Therefore, regarding diet, it is crucial to strictly adhere to a standard of low salt, low fat, and low purine. Avoid eating fried foods and animal offal, and do not consume carbohydrate-rich foods and sugary drinks. Additionally, for patients with high uric acid levels, it is advised not to consume excessive seafood and rich broths. It is recommended to avoid eating late-night meals, fried foods, and grilled items. The foods that should be avoided by patients with obesity are mainly determined based on the levels of blood sugar, blood lipids, blood pressure, and blood uric acid.

Can obesity be treated?

Obesity is treatable. Generally, the treatment of obesity mainly includes several aspects: First, dietary intervention; second, increased physical activity; third, correcting bad behavioral habits; some cases may require medication and surgery. Dietary treatment mainly involves reducing calorie intake and recommending a low-sugar diet. Physical exercise generally requires three to five days of activity per week, with 30-40 minutes each day being appropriate. It also includes correcting some poor dietary habits and enhancing self-monitoring, including records of food intake and daily physical activity. Medication treatment is an option for individuals with a body mass index (BMI) of 30 or higher, or a BMI of 27 or higher who also have obesity-related comorbidities. This treatment can be combined with exercise and dietary behavioral corrections. Furthermore, for those with a BMI of 40 or higher, or a BMI between 35-39.9 with one or more severe obesity-related complications such as hypertension, heart failure, type 2 diabetes, or sleep apnea, surgical treatment may be considered.

Obesity weight loss methods

The treatment of obesity involves two main components. One is reducing calorie intake and the other is increasing calorie consumption, mainly emphasizing a comprehensive treatment based primarily on diet and exercise. Secondly, medications or surgical treatments can be utilized. In the case of secondary obesity, it is important to treat the underlying cause. So, what is behavioral therapy? It involves educating patients and their families about obesity and its risks, enabling them to cooperate with the treatment, adopt a healthy lifestyle, change dietary and exercise habits, and maintain these changes consciently in the long term as the foremost and most important measures in the treatment of obesity. Thirdly, controlling diet and increasing physical activity are crucial. Individuals with mild obesity can control their total food intake with a low-calorie, low-fat diet. For those with moderate to severe obesity, total calorie intake should be strictly controlled, with women limited to 1200-1500 kcal per day and men to 1500-1800 kcal per day. Following this standard, a weight loss of 1-2 pounds per week can be achieved. Furthermore, for severe obesity, medications can be used to reduce weight, which can then be maintained. If necessary, surgical procedures such as jejunoileal bypass or biliopancreatic diversion surgery can be considered.

What department should I register for obesity?

For obesity, one should register for an appointment in the endocrinology department. Obesity is a chronic metabolic disease caused by excessive accumulation or abnormal distribution of body fat. Obesity often occurs due to a higher calorie intake than expenditure in the body, resulting in excessive fat accumulation and thus overweight and bulky physique. An actual weight measurement exceeding 20% of the standard weight, and a fat percentage exceeding 30% can be classified as obesity. In endocrinology, obesity is generally divided into primary and secondary types. Some secondary factors, such as hypothalamic-pituitary disorders, hypercortisolism, hypothyroidism, hypogonadism, insulinomas, etc., can cause secondary obesity, therefore, it is appropriate to consult the endocrinology department for obesity.

What department do you see for obesity?

The preferred specialty is endocrinology and metabolism because obesity itself is a metabolic disease. Besides the commonly known simple obesity, there is also a type called secondary obesity. The distinction between the two is that in simple obesity, the body does not suffer from any other disease; weight gain is merely caused by unscientific diet, irregular lifestyle, and lack of exercise, which can be resolved through some scientific methods. Another type is called secondary obesity, such as a common disease in endocrinology called Cushing's syndrome. It is caused by a tumor or hyperplasia in the pituitary or adrenal glands, or other reasons that lead to an excessive secretion of cortisol in the blood, consequently causing a redistribution of body fat, leading to moon face, buffalo hump, and accumulation of subcutaneous fat in the abdomen. Common in endocrinology, hypothyroidism can also lead to weight gain. This requires endocrinology specialists to diagnose and identify the specific condition in order to provide appropriate treatment.
