Activity of Thyroid Gland During Fasting and Realimentation with Diets High in Carbohydrate. ∗

Abstract

Summary and conclusions

1) Activity of thyroid glands of dogs as determined by serum PBI and I¹³¹ uptake is not significantly altered during prolonged fasting or realimentation with diets high in carbohydrate. 2) The high systolic pressure and rapid pulse with low or normal diastolic pressure which is produced by a diet high in carbohydrate fed at the luxus consumption level of 120 cal/M²/hr after a prolonged fast is strikingly similar to the hemodynamic effect of thyroid powder but it is not due to increased thyroid activity according to the indices studied.
