Why only fat buttocks, thighs, and belly

Fat accumulation in the buttocks, thighs, and abdomen is mainly related to hormone distribution, adipocyte characteristics, and lifestyle habits. This type of fat is called subcutaneous fat, and its distribution is influenced by multiple factors such as estrogen, insulin sensitivity, genetic factors, sedentary lifestyle, lack of exercise, and high sugar and high-fat diet.

1. Hormone Distribution

Estrogen promotes fat accumulation in the buttocks and thighs, which is a physiological requirement for female reproductive function. Male androgens are more likely to cause visceral fat accumulation and abdominal obesity. Hormonal changes such as pregnancy and menopause can exacerbate this tendency.

2. Characteristics of adipocytes

Lower body adipocytes have higher activity of lipoprotein lipase, stronger storage efficiency but slower decomposition rate. Abdominal adipocytes have fewer beta receptors, poor response to catecholamine hormones, and are more difficult to mobilize and consume.

3. Genetic factors

Pear shaped or apple shaped body types have familial heritability. Mutations in specific genes such as FTO genes can affect the distribution pattern of fat, making it easier for some populations to accumulate fat in specific areas.

4. Prolonged sitting without exercise

Maintaining a sitting position for a long time can reduce the frequency of lower limb muscle contractions, slow down local blood circulation, and decrease the rate of fat breakdown metabolism. Core muscle weakness can also lead to increased abdominal fat accumulation.

5. High sugar and high-fat diet

Excessive refined carbohydrates and high-fat foods can stimulate sustained insulin secretion and promote fat synthesis. Alcohol intake can inhibit liver fat metabolism, particularly leading to an increase in visceral fat.

Comprehensive measures should be taken for local obesity: perform lower limb resistance training such as squats and lunges at least 3 times a week, combined with aerobic exercise to improve overall fat burning efficiency; Control the intake of added sugar and saturated fat, increase high-quality protein and dietary fiber; Avoid prolonged sitting and get up and move around every hour. Perform abdominal breathing exercises before bedtime. Stubborn local fat can be treated with medical beauty methods such as cryolipolysis, but it needs to be selected under the guidance of a professional physician.
