The Claim
In 6–8 week old piglets, food restriction reduces thyroidal secretion of triiodothyronine (T3) from 30% to 17% of total production and reverse T3 (rT3) from 7.2% to 2.9%, indicating suppression of direct thyroid hormone output during energy deficit.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In 6–8 week old piglets, reducing food intake lowers the amount of triiodothyronine (T3) and reverse T3 secreted by the thyroid gland, indicating reduced thyroid hormone production during energy deficit.
See the scientific wording
In 6–8 week old piglets, food restriction reduces the thyroidal secretion of triiodothyronine (T3) from 30% to 17% of total production and reverse T3 (rT3) from 7.2% to 2.9%, indicating a suppression of direct thyroid hormone output during energy deficit.
When food is scarce, the thyroid gland produces less of the active hormone T3 and its inactive form rT3. The body compensates by converting more of the stored thyroid hormone T4 into rT3 instead of T3 in tissues like the liver and muscle. This reduces overall metabolic activity and saves energy and protein.
What the research says
1 studyWhen young piglets don’t eat, their thyroid gland makes less of two important hormones (T3 and rT3) directly, and their body starts making more of these hormones from other sources instead. This helps them save energy when food is scarce.
