Why is thyroid weight loss stubborn?

If you are a thyroid patient, you already know how hard it is to lose weight. Some of you might already believe that thyroid weight gain is an inevitable part of your journey.

But why is it so difficult to lose weight with hypothyroidism?

Well, the answer is in your TSH levels. Elevated TSH levels slow down your metabolism significantly. A slow metabolism makes it harder for your body to lose weight.

TSH levels can be elevated even before you show symptoms. So, if you notice any undesired weight gain, thyroid weight gain to be precise, you must get your thyroid levels tested.

With hypothyroidism, it's common to feel tired and low on energy. Exercising when you are already tired doesn't sound like fun. At the same time, you might also crave sweets, which can contribute to your thyroid weight gain. You might also have specific resistance problems such as Leptin resistance and insulin resistance. Research shows that both can contribute to weight gain and make it harder for you to drop the extra pounds.

Traditional treatment focuses on treating only the symptoms with hormone replacement medications such as levothyroxine. So, the best way for losing weight with hypothyroidism is to treat the root cause of the disease. Treating isolated symptoms won’t help in weight loss.

Functional medicine thrives on diagnosing the root cause and solving your queries on how to cure hypothyroidism.

How does diet help prevent thyroid weight gain?
