How is slow metabolism caused in the human body

Slow metabolic function may be caused by genetic factors, hypothyroidism, malnutrition, lack of exercise, chronic diseases, and other reasons. Metabolic rate is influenced by multiple factors and needs to be comprehensively judged based on specific circumstances.

1. Genetic factors

Some populations are born with lower basal metabolic rates, which is closely related to genetic inheritance. Individuals with slower parental metabolism often exhibit similar metabolic characteristics. This type of situation can be improved by increasing muscle mass, regular sleep patterns, etc., but it is difficult to fundamentally change genetic characteristics.

2. Hypothyroidism

Insufficient secretion of thyroid hormones can significantly reduce metabolic rate, often accompanied by symptoms such as cold sensitivity, weight gain, and fatigue. It may be related to factors such as Hashimoto's thyroiditis and iodine deficiency. Diagnosis should be confirmed through thyroid function examination, and medication such as levothyroxine sodium tablets should be used under the guidance of a doctor for regulation.

3. Malnutrition

Long term insufficient protein intake can lead to muscle loss, vitamin B deficiency affects energy conversion processes, and iron deficiency reduces blood oxygen carrying capacity. These nutrient deficiencies can cause the body to enter energy-saving mode, manifested as a decrease in metabolic function. Balanced intake of high-quality protein, whole grains, and dark vegetables can help improve.

4. Lack of exercise

A sedentary lifestyle can lead to gradual muscle atrophy and a decrease in basal metabolic rate every year. Muscle tissue is the main site for energy consumption, and a decrease in its content directly leads to a decrease in resting energy expenditure. It is recommended to perform resistance training combined with aerobic exercise every week to effectively improve muscle mass and metabolic activity.

5. Chronic diseases

diabetes, cardiovascular diseases and other chronic diseases are often accompanied by metabolic abnormalities. Insulin resistance can interfere with glucose metabolism processes, and chronic inflammatory states may inhibit mitochondrial function. This type of situation requires targeted treatment for the primary disease, along with dietary management and moderate exercise to improve metabolic status. Improving metabolic function requires establishing a healthy lifestyle. Ensuring sufficient daily sleep helps regulate the secretion of leptin and growth hormone, avoiding staying up late and disrupting biological rhythms. Increasing the proportion of protein in diet, choosing complex carbohydrates, and supplementing food components such as capsaicin and caffeine in moderation can temporarily improve metabolic rate. Long term sedentary individuals are advised to get up and move around every hour, accumulating effects through fragmented exercise. If metabolic problems persist after adjusting lifestyle, timely medical attention should be sought to screen for organic diseases such as thyroid.
