Blood Sugar Spikes & Insulin Resistance

Junk food high in sugar causes sudden spikes in blood glucose. This forces your body to overproduce insulin, leading to insulin resistance — a key factor in diabetes and hormonal imbalance.

Elevated Cortisol (Stress Hormone)

Processed foods trigger inflammation, raising cortisol levels. High cortisol leads to anxiety, poor sleep, belly fat, and disrupts the balance of other key hormones like melatonin and serotonin.

Leptin Resistance: Constant Hunger

Leptin tells your brain you're full. But junk food can make your brain ignore these signals, leading to overeating, weight gain, and further hormonal chaos.

Disrupted Thyroid Function

Sodium-laden and chemical-heavy junk food interferes with thyroid hormones (T3, T4), slowing metabolism and causing fatigue, weight gain, and low energy.

Sex Hormones Imbalance (Testosterone & Estrogen)

Unhealthy fats and processed ingredients can reduce testosterone in men and raise estrogen in women — causing issues like acne, low libido, PCOS, and menstrual irregularities.
