What is the reason for slow metabolism in the human body

Slow metabolism in the human body may be caused by aging, lack of exercise, hypothyroidism, malnutrition, chronic diseases, and other factors. Slow metabolism is usually manifested as symptoms such as weight gain, fatigue, chills, dry skin, constipation, etc.

1. As age increases, the body's muscle mass gradually decreases, and the basal metabolic rate naturally decreases. This is a normal physiological phenomenon, and the basal metabolic rate will decrease by a certain amount every ten years after the age of 30. Regular strength training can help slow down muscle loss, and increasing protein intake appropriately can also help maintain muscle mass.

2. Lack of exercise

Prolonged sitting can lead to muscle atrophy and decreased metabolic rate. Exercise can increase muscle mass, increase mitochondrial count, and thus improve energy expenditure efficiency. It is recommended to combine aerobic exercise and resistance training every week, such as brisk walking, swimming, dumbbell training, etc.

3. Hypothyroidism

Insufficient secretion of thyroid hormones can significantly reduce basal metabolic rate. This situation may be related to autoimmune diseases, iodine deficiency, or thyroid surgery. Patients often experience symptoms such as weight gain, dry skin, and decreased memory. Need to seek medical attention to check thyroid function indicators.

4. Malnutrition

Long term dieting or imbalanced diet can lead to the body entering an "energy-saving mode". Insufficient protein intake can affect muscle synthesis, while vitamin and mineral deficiencies can affect enzyme activity. It is recommended to ensure a balanced intake of high-quality protein, complex carbohydrates, and healthy fats.

5. Chronic diseases

diabetes, cardiovascular diseases and other chronic diseases will affect the energy metabolism process. These diseases may lead to issues such as insulin resistance and mitochondrial dysfunction. Controlling the primary condition and improving lifestyle are key to enhancing metabolism, which requires comprehensive treatment under the guidance of a doctor. Improving metabolism requires a multi-faceted approach. Ensuring adequate sleep can help regulate levels of leptin and ghrelin. Drinking over 2000 milliliters of water per day can promote the elimination of metabolic waste. Moderate consumption of foods such as chili peppers and green tea may temporarily increase metabolic rate. Long term sedentary individuals are advised to get up and engage in simple stretching exercises every hour. For metabolic abnormalities caused by suspected thyroid problems or other diseases, timely medical examination should be sought, and self medication or health supplements should not be taken. Establishing regular dietary and exercise habits is the foundation for maintaining healthy metabolism, and it is necessary to develop sustainable lifestyle adjustment plans based on individual circumstances.
