Respiratory quotient in obese subjects

Influence of vitamin A consumption on resting metabolic rate and fasting respiratory quotient in severely obese subjects.

OBJECTIVE To study whether or not the amount of vitamin A consumed affects the resting metabolic rate (RMR) and fat oxidation at rest in severely obese subjects. MATERIALS AND METHODS In 239 obese subjects, RMR and fasting respiratory quotient (RQ) were determined by indirect calorimetry. Vitamin A consumption was calculated by the Czech PC program 'Nutrition'. The relation between the intake...

Reduced respiratory capacity in muscle mitochondria of obese subjects.

BACKGROUND/AIMS The extent of weight gain varies among individuals despite equal calorie overconsumption. Furthermore, weight gain is often less than expected from energy excess. This suggests differences in metabolic efficiency and basal metabolism. Since mitochondrial uncoupling accounts for a substantial portion of the basal metabolic rate, we compared skeletal muscle mitochondrial respirati...

The respiratory quotient in the newborn pig.

I . Rates of oxygen consumption and carbon dioxide production were measured in pigs from birth to 3 days of age in an open-circuit system. 2. The mean respiratory quotient (RQ) during the first 6 h following birth was 0.95 in fasted pigs and 0.91 in pigs which were allowed to feed. 3. The RQ fell during the remainder of the first postnatal day to mean values close to 0.85, whether the pigs were...
