Summary

To examine determinants of basal metabolic rate we studied 66 Type 2 (non-insulin-dependent) diabetic and 24 healthy age- and weight-matched control subjects with indirect calorimetry and infusion of [3H-3-] glucose. Eight Type 2 diabetic patients were re-studied after a period of insulin therapy. Basal metabolic rate was higher in Type 2 diabetic patients than in control subjects (102.8 ± 1.9 J · kg LBM−1-min−1 vs 90.7 ± 2.8 J · kg LBM−1;min−1; p<0.01) and decreased significantly with insulin therapy (p <0.01). The basal rate of hepatic glucose production was higher in Type 2 diabetic patients than in control subjects (1044.0 ± 29.9 vs 789.3 ± 41.7 μmol/min; p <0.001) and decreased after insulin therapy (p <0.01). Hepatic glucose production correlated positively with basal metabolic rate both in Type 2 diabetic patients (r = 0.49; p <0.001) and in control subjects (r = 0.50; p<0.05). Lipid oxidation was increased in Type 2 diabetic patients compared with control subjects (1.68 ± 0.05 vs 1.37 ± 0.08 μmol · kg LBM−1 · min−1'; p <0.01) and decreased significantly after insulin therapy (p <0.05). The rate of lipid oxidation correlated positively with basal metabolic rate both in Type 2 diabetic patients (r = 0.36; p <0.01) and in control subjects (r = 0.51; p <0.01). These data demonstrate that basal metabolic rate, rates of hepatic glucose production and lipid oxidation are interrelated in Type 2 diabetic patients. A reduction of the hepatic glucose production, however, is associated with a reduction in lipid oxidation, which in turn, may result in a reduction in basal metabolic rate.
