Resting metabolic rate and diet-induced thermogenesis in restrained and unrestrained eaters.
OBJECTIVE
The hypothesis was studied whether restrained eaters had reduced resting metabolic rate (RMR) and diet-induced thermogenesis (DIT) and whether the effect was caused by weight cycling.


METHODS
12 restrained and 12 unrestrained eaters (classified by the Three Factor Eating Questionnaire) were studied with regard to RMR an DIT by direct calorimetry using a ventilated hood system. In a second study 12 weight cycling restrained eaters and 12 weight stable restrained eaters were compared.


RESULTS
Restrained eaters had significantly lower RMR than unrestrained eaters. No difference in DIT was found. Weight cycling and no weight cycling restrained eaters did not differ with regard to RMR and DIT.


CONCLUSIONS
These data indicate that restrained eating but not weight cycling significantly reduces RMR.
