Diet Chart for Thyroid Patients: What to Eat and Avoid

The thyroid is a small but essential gland located at the base of your neck. It produces two key hormones — thyroxine (T4) and triiodothyronine (T3) — which regulate your body’s metabolism, energy levels, body temperature, heart rate, and overall health. When thyroid function is disrupted, it can affect nearly every system in your body.

Thyroid disorders generally fall into two categories:

Hypothyroidism — the thyroid gland produces less hormone than the body needs, which slows down metabolism and often leads to fatigue, weight gain, and sluggishness.

Hyperthyroidism — the thyroid gland produces excess hormone, speeding up metabolism abnormally and often causing weight loss, anxiety, and rapid heartbeat.

Diet plays a significant role in managing both conditions. Below is guidance for each.
