Thermogenesis and the effect of injected catecholamines on the XXXX consumption of cafeteria-fed @entity35 .

@entity4962 @entity935 @entity26 @entity2922 @entity35 @entity1063
1. The @entity26 consumption (VO2) of unrestrained @entity35 given a 'cafeteria' (high energy, high fat) or control diet was studied. The resting values of @entity4962 were the same in each dietary group, whether maintained at 26 degrees C or 6 degrees C. This negative finding suggests that cafeteria feeding is not an important cause of diet-induced thermogenesis (DIT). 2. The response of each group of @entity35 to injected @entity1063 or @entity935 was also studied. Each @entity2922 could increase VO2 values but the response was much less in cold-adapted @entity35 measured at 6 degrees C. In all experimental circumstances the @entity935 response exceeded that of @entity1063 . There was no evidence that the cafeteria diet consistently increased the response to either @entity2922 . 3. These results suggest that DIT cannot be equated with non-shivering thermogenesis (NST). Furthermore, it is suggested that @entity935 would be a better agent for measuring the @entity26 equivalent of NST, since it would stimulate the @entity935 receptors as well as the alpha- and beta-adrenoreceptors of brown fat.
