What is the reason why a person is not overweight but has a big belly

People who are not overweight but have a large belly may be related to factors such as visceral fat accumulation, abdominal muscle relaxation, pelvic tilt, abnormal hormone levels, and intestinal bloating. This type of local fat accumulation is often unrelated to overall weight and requires targeted analysis of the reasons.

1. Accumulation of visceral fat

Long term high sugar and high-fat diet can lead to visceral fat deposition, and even with normal weight, abdominal distension may occur. This type of fat wraps around internal organs and is more metabolically active than subcutaneous fat, which can easily trigger insulin resistance. It is recommended to reduce visceral fat through aerobic exercise combined with core training, such as brisk walking, swimming, etc., done multiple times a week.

2. Abdominal muscle relaxation

Postpartum women or those who lack exercise often experience separation of the rectus abdominis muscle. Insufficient abdominal muscle tone can lead to protrusion of internal organs. The loss of collagen caused by aging can also exacerbate skin sagging. Strengthens the transverse abdominal muscles through activities such as plank support and supine leg lifting, and if necessary, wears shapewear to assist in correction.

3. Pelvic Anterior Tilt

Sedentary individuals are prone to pelvic anterior tilt due to hip flexor muscle tension, which makes the abdomen visually more prominent. This abnormal posture can alter the curvature of the lumbar spine, causing the abdominal muscles to remain stretched for a long time. It needs to be improved by stretching the iliopsoas muscle and strengthening the gluteal muscle, and the bridge movement in yoga is significantly helpful.

4. Abnormal hormone levels

An increase in the stress hormone cortisol can promote fat concentration in the abdomen, and a decrease in estrogen levels during menopause can also alter the pattern of fat distribution in women. When hypothyroidism occurs, the basal metabolic rate decreases, and even with normal food intake, abdominal fat accumulation may still occur. It is recommended to test hormone levels and adjust them under the guidance of a doctor if necessary.

5. Intestinal bloating

Patients with lactose intolerance or irritable bowel syndrome often experience bloating due to digestive disorders. Food intolerance and imbalanced gut microbiota can lead to increased gas production, resulting in sustained abdominal distension. You can try a low FODMAP diet, supplement probiotics to improve the intestinal environment, and avoid gas producing foods such as beans and onions. Improving lower abdominal protrusion requires a comprehensive evaluation of the specific causes, and it is recommended to record dietary logs and observe the pattern of bloating. In addition to targeted training, daily water intake should be ensured, refined carbohydrates intake should be controlled, and dietary fiber supplementation should be increased. Lack of sleep can exacerbate cortisol secretion, so it is necessary to maintain a regular schedule. If accompanied by abnormal bowel movements or pain, seek medical attention promptly to rule out organic diseases. Long term sedentary individuals are advised to get up and move around every hour, avoiding wearing overly tight clothing that compresses the abdominal cavity.
