Thyroid hormones play a crucial role in regulating and supporting carbohydrate metabolism. They increase the rate of gluconeogenesis, which is the process of producing glucose from non-carbohydrate sources, as well as enhance intestinal glucose absorption. In addition, these hormones stimulate the synthesis of enzymes that are involved in carbohydrate metabolism, leading to an increase in overall metabolic activities. By promoting these processes, thyroid hormones help maintain normal blood glucose levels and contribute to the body's energy balance, making their role in carbohydrate metabolism vital for overall health and metabolic function.

The other options do not accurately reflect the action of thyroid hormones; inhibiting metabolic processes would go against their known function, while stating that they have no effect on metabolism undermines their regulatory influence. Limiting their effect to only fat metabolism ignores their significant involvement in carbohydrate and protein metabolism as well.
