Causes of stubborn weight gain

Causes of Stubborn Weight Gain

Many women find that even with mindful eating and regular exercise, the scale barely budges—or worse, creeps upward. Stubborn weight gain isn’t always about willpower. It’s often your body’s way of signaling deeper imbalances. Understanding the underlying causes can help you approach weight loss with compassion and strategy rather than frustration.

1. Hormonal Imbalances

• Cortisol (Stress Hormone): Chronic stress keeps cortisol elevated, which can lead to fat storage around the midsection.

• Thyroid Hormones: Low thyroid function (hypothyroidism) slows metabolism, making weight loss difficult.

• Sex Hormones: Low estrogen, common during menopause can promote fat storage particularly in the abdomen and hip region.

2. Insulin Resistance and Blood Sugar Spikes

Frequent blood sugar highs and lows can trigger cravings and fat storage. Over time, cells become less responsive to insulin, making it harder for your body to use glucose effectively. Insulin is a fat storage hormone and can cause the body to remain in fat storage mode.

3. Poor Sleep Quality

Even one night of inadequate sleep can disrupt hunger hormones (ghrelin and leptin), making you hungrier and less satisfied. Chronic sleep deprivation also raises cortisol, further complicating weight loss.

4. Digestive Health and Inflammation

Gut imbalances or low-grade inflammation can affect nutrient absorption and trigger immune responses that promote weight retention. Bloating or bowel irregularities may be clues.

5. Medications

Certain medications—including some antidepressants, corticosteroids, and birth control—can contribute to weight gain by affecting appetite, metabolism, or fluid retention.

6. Age and Muscle Loss

With age, muscle mass naturally declines, lowering your metabolic rate. Less muscle means fewer calories burned, even at rest.

7. Overeating or undereating

Both overeating and undereating can cause a stress trigger on the body. This can cause the body to retain water and prevent weight loss.

The Takeaway

Stubborn weight gain is often multifactorial. Instead of drastic dieting or punishing workouts, look at your whole health picture—hormones, sleep, stress, gut health, and lifestyle habits. Small, sustainable changes like prioritizing protein, lifting weights, getting quality sleep, and managing stress can make a profound difference over time.
