Dr. Tabatha Barber argues that insulin drives weight gain by raising cortisol, depleting the adrenals, increasing water retention, and suppressing thyroid function. She presents insulin as the key to understanding unexplained weight gain and rising hypothyroidism rates.
Well, what is insulin? It's a fat storing hormone. And then also it's increasing cortisol in the body. It is depleting the adrenals. So when your adrenals are depleted, you need more cortisol to try to just get out of bed. And with that, that's a fat storing hormone. It's also increasing the antidiuretic hormone. So you're retaining more water, it's increasing oxidative stress, it's depressing the thyroid function. So more people than ever are walking around with hypothyroidism and they don't know why they put on 5, 10, 20 pounds out of nowhere.
