Can individuals with hypothyroidism follow a ketogenic diet?

Hypothyroidism contraindicates the ketogenic diet. Clinically, this condition arises due to reduced metabolic activity. Typical manifestations include pallor, weight gain (not weight loss—note correction), memory impairment, cognitive decline, and slowed mental and physical responses. Hypothyroidism is treated with levothyroxine (e.g., Synthroid®); patients require regular monitoring of thyroid hormone levels to adjust medication dosage accordingly. Patients should also maintain emotional well-being and follow a balanced, thyroid-friendly diet.
