You finally got your thyroid tested.

Your doctor says everything looks normal…
but you still feel:

• exhausted

• cold

• foggy

• constipated

• stuck at the same weight

This is incredibly common — and very confusing.

You’re not imagining it.

Your Body Runs on Active Thyroid Hormone

Your thyroid mostly produces T4, a storage hormone.

Your cells actually need T3, the active hormone that controls:

• metabolism

• energy

• digestion

• temperature

• mental clarity

Your body has to convert T4 → T3.

If that conversion slows down, symptoms appear — even when labs look okay.

What Slows Thyroid Function

Your body lowers thyroid activity when it senses stress.

Common triggers:
• irregular eating
• under-fueling
• poor sleep
• chronic stress
• low iron
• inflammation

Your metabolism isn’t broken — it’s protective.

Why Nutrition Helps

We focus on giving the body safety signals:

• regular meals

• enough protein

• steady energy intake

When the brain feels safe, thyroid activity improves.
