• Eating high calorie diets, fruits and vegetables can increase thyroid activity.
• Eating sugar does too, although transitorily, increase thyroid activity.
• Eating too much of proteins (meat and poultry), or eating very low calorie diet may considerably lower thyroid activity by slowing down the conversion of T4 to T3, and also by lowering down the production of both thyroid hormones by the thyroid gland.
