What is the reason for slow metabolism after good absorption

Good absorption and slow metabolism may be related to genetic factors, dietary structure, lack of exercise, hypothyroidism, insulin resistance, and other reasons. This type of constitution can easily lead to excess energy, increasing the risk of obesity and metabolic syndrome.

1. Genetic factors

Some populations have higher intestinal absorption efficiency and lower basal metabolic rate due to genetic differences. This type of constitution usually manifests as a high utilization rate of food nutrients, but slower calorie consumption. It is recommended to understand one's metabolic characteristics through genetic testing and develop personalized dietary plans to avoid excessive intake of high calorie foods.

2. Dietary Structure

Long term intake of high-fat and high sugar foods can enhance intestinal absorption capacity while slowing down metabolic rate. Refined carbohydrates and saturated fatty acids can reduce mitochondrial activity and affect energy conversion efficiency. Adjusting the ratio of protein to dietary fiber in the diet and increasing the intake of whole grains and vegetables can help improve metabolic balance.

3. Lack of exercise

Lack of regular exercise can lead to a decrease in muscle mass and a sustained decline in basal metabolic rate. A sedentary lifestyle can help the body adapt to a low-energy state and further inhibit fat oxidation and decomposition. Combining resistance training with aerobic exercise every week can effectively improve resting energy expenditure.

4. Hypothyroidism

Insufficient secretion of thyroid hormones can significantly reduce cellular metabolic activity, and common symptoms include cold sensitivity, fatigue, and weight gain. Hypothyroidism may be caused by autoimmune diseases, iodine deficiency, or medication factors. Diagnosis requires testing for thyroid stimulating hormone levels, and if necessary, medication such as levothyroxine sodium tablets should be used under the guidance of a doctor.

5. Insulin resistance

Decreased insulin sensitivity can lead to impaired glucose utilization, promoting increased fat synthesis and decreased breakdown. This condition is often accompanied by abdominal obesity and acanthosis nigricans, which may develop into type 2 diabetes. Improving insulin resistance requires controlling refined sugar intake, and doctors may recommend the use of drugs such as metformin as adjuvant therapy.

For those with a slow metabolism and good absorption, it is recommended to adopt a high protein and high fiber diet, ensure moderate intake of nuts and deep-sea fish daily, and provide essential fatty acids and high-quality protein. Regular strength training can increase muscle mass and improve basal metabolic rate. Avoid staying up late and excessive dieting, as these behaviors can further lower metabolic levels. Regularly monitor blood sugar, blood lipids, and thyroid function, seek guidance from professional nutritionists or endocrinologists when necessary, and develop a scientific weight management plan. Maintaining a long-term healthy lifestyle is more beneficial for metabolic regulation than short-term extreme weight loss.
