Why doesn't a person lose weight but their face looks thin

The appearance of losing weight on the face is usually related to changes in local fat distribution, water metabolism, or muscle tightness. The main influencing factors include the disappearance of facial edema, improvement of muscle lines, differences in local fat metabolism, changes in skin tightness, and adjustment of visual proportions.

1. Reduction of facial edema

A high salt diet or lack of sleep may cause temporary facial edema. Adjusting diet to reduce sodium intake or following a regular schedule can improve water retention and make facial contours clearer. This situation is not related to overall fat loss and belongs to short-term physiological changes.

2. Muscle Line Enhancement

Exercise may enhance facial and neck muscle tension, especially the tightening of the chewing and latissimus muscles, which can change the jawline. Strength training promotes collagen synthesis, enhances skin support, and visually produces a slimming effect.

3. Differences in local fat metabolism

Adipose cells in different parts of the human body have different sensitivities to hormones. When the stress hormone cortisol increases, facial fat may preferentially decompose. This selective metabolism will not significantly reduce weight, but will alter facial plumpness.

4. Changes in Skin Tightness

When aging or collagen loss leads to skin laxity, improving elasticity through hydration care or radiofrequency beauty can make facial contours appear firmer. This change belongs to organizational state adjustment rather than actual weight loss.

5. Visual Proportion Adjustment

Hairstyle changes, makeup modifications, or neck posture adjustments may reduce the visual area of the face through light and shadow effects. After the muscles in the shoulders and neck relax, changes in the head to body ratio can also create the illusion of a slimmer face shape.

It is recommended to promote overall fat metabolism through regular aerobic exercise combined with facial massage to avoid excessive dieting and loss of facial collagen. Maintaining sufficient daily water intake and reducing the intake of high salt snacks can help maintain facial water salt balance. If accompanied by other abnormal symptoms such as obvious weight loss on one side of the face, it is necessary to promptly investigate thyroid or neurological diseases. Long term healthy weight loss should focus on changes in body fat percentage rather than just weight numbers.
