Weight gain in hypothyroidism isn’t just sluggish metabolism—it’s additionally driven with the aid of leptin resistance and insulin dysregulation.
- Leptin Resistance: Leptin is a hormone that tells your brain you are complete and allows for modification of fat burning. In hypothyroidism, leptin levels may be abnormally excessive, but the mind will become immune to it. This indicates your frame holds onto fats in place of burning them, making weight loss extraordinarily hard.

Stress and sleep are regularly neglected in weight loss, but they’re essential for thyroid health. Excessive cortisol levels (your frame’s stress hormone) can block the conversion of T4 to energetic T3, the hormone your frame needs to burn calories. Negative sleep disrupts hormone stability, increases ghrelin (a starvation hormone), and reduces leptin (a fullness hormone).
Purpose for seven to nine hours of restorative sleep nightly. Use blue-light blockers and keep your room cool to optimize melatonin production.
