Of the hypotheses proposed to explain specific dynamic action (SDA), it is suggested that the ‘protein synthesis/growth’ theory offers the best basis for further research. In the light of this, the relationships between rates of protein synthesis and metabolic rates are examined. Both of which are depressed with increasing periods of starvation and there appears to be a link between rates of protein synthesis and thyroid activity. SDA may represent a short‐term increase in rates of protein synthesis and turnover following feeding and the process is possibly regulated via plasma levels of thyroid hormones.
