Abstract: Introduction: The concerns about body weight are very wide-spread in women because of societal pressures about thinness. Dietary restraint is defined as a conscious control of food intake with concerns about shape and weight. Since thermogenic deficit might hamper body weight management, it could promote an increase in dietary restraint in subjects willing to control their body weight. The main objective of this study was therefore to verify whether dietary restraint was associated with a thermogenic deficit. Methods: We thus recruited 144 overweight and obese (BMI = 25-40 kg/m2) premenopausal women characterized by a preoccupation about their weight and eating. Dietary restraint was assessed by the Three-Factor Eating Questionnaire (TFEQ). Resting metabolic rate (RMR) was measured by indirect calorimetry and compared with its predicted value (Harris–Benedict formula). Results: Measured values of RMR were significantly lower than their predicted levels (1360 ± 168.5 kcal/day vs 1521.3 ± 100.9 kcal/day ; P ≤ 0.001).There was no association between scores of dietary restraint and the difference between measured and predicted RMR. In conclusion, variations in dietary restraint do not seem to be related to thermogenic deficit in overweight-obese women expressing concerns about their body weight.
