The Central Effects of Thyroid Hormones on Appetite

Table 1

Effect of TRH, TSH, and T3 on food intake. Central administration of TRH and TSH in rodents causes a reduction in food intake [8, 12, 13]; similar effects on food intake are seen following peripheral administration of TRH [14]. Central and peripheral administration of T3 increases food intake [9–11]. TRH: thyrotropin releasing hormone; TSH: thyroid-stimulating hormone; T3: triiodothyronine.
