Brief summary
Through the values of respiratory quotient (RQ) it is possible to estimate the utilization of energy substrates by the body, or if there is a higher or lower fat oxidation. Experimental and clinical studies have shown that after Roux-en-Y Gastric Bypass (RYGBP) there is a decrease in the values of RQ, which may be associated with increased lipid oxidation in the postoperative period. Diet Induced Thermogenesis (DIT) is an important part of Total Energy Expenditure. We would like to know how it functions among RYGBP patients. The purpose of this study is to evaluate the RQ and DIT of patients in the post operative phase and compare the result with a control group consisting of morbid obese population.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Diet Induced Thermogenesis | 20min after standard meal | To examine the possible changes in the thermic effect of food, the patients received a standard meal. They then repeated the test 20 minutes after eating to obtain a reading of the metabolic rate by considering the DIT and RQ in the postprandial period. DIT was calculated as the difference between post prandial metabolic rate and RMR. |
