Abstract

The aim of this research was to assess the influence of dietary intervention on weight loss and resting energy expenditure (REE) in 20 obese and overweight adolescents (BMI = 29 +/- 3,8 kg/m2) aged 15-18 years. Nutritional habits and nutritional status were estimated before and after the introduction of low-calorie diet. Measurements of REE were carried out by indirect calorimetry in a respiratory chamber Nutritional intervention had a significant influence in decreasing body weight (from 85 +/- 14.3 kg to 82.5 +/- 12.8 kg), BMI and fat mass. Muscle mass was found to be significantly elevated (p < 0.050). REE did not decline significantly due to nutritional intervention (p > 0.05; p = 0.84).

摘要

本研究的目的是评估饮食干预对20名年龄在15至18岁的肥胖和超重青少年（BMI = 29 ± 3.8 kg/m²）体重减轻和静息能量消耗（REE）的影响。在引入低热量饮食之前和之后，对营养习惯和营养状况进行了评估。通过呼吸室内的间接测热法测量REE。营养干预对减轻体重（从85 ± 14.3 kg降至82.5 ± 12.8 kg）、BMI和脂肪量有显著影响。发现肌肉量显著增加（p < 0.050）。由于营养干预，REE没有显著下降（p > 0.05；p = 0.84）。
