There’s a lot of hullabaloo about thyroid health among the nutritional community, particularly among those trying to lose weight, and for good reason. The thyroid – a butterfly-shaped gland in your neck – releases a hormone that increases your metabolism. It’s kinda’ like a dimmer switch for your ability to burn calories. And, unfortunately for dieters, it’s well known that thyroid activity decreases as you lose weight. This means that, in general, as you lose weight, you burn fewer and fewer calories and it becomes harder to lose more weight. It’s as if the body is trying to sabotage your weight loss! Well, it is.

Basically the Hypothalamus (located in the brain) release TRH (Thyrotropin Releasing Hormone) which then makes the pituitary (located in the brain) release TSH (Thyroid Stimulating Hormone). TSH makes the thyroid gland (located in the neck) release T4. T4 is converted to T3 (the active hormone that then affects the tissues). Both T3 and T4 can inhibit or decrease/stop the release of both TRH and TSH.
