Abstract

While the benefits of weight loss on fat mass and metabolic outcomes have been well established, it is also causing undesirable catabolism of other tissues, including muscle mass. Loss of muscle mass during weight loss from dietary restrictions as part of medical nutrition therapy (MNT) may lead to a reduction in muscle strength and resting metabolic rate, making weight maintenance even harder. This study aimed to determine body composition in patients with morbid obesity following medical nutrition therapy. Using a retrospective pre-post analysis study design, we collected patient's records who were diagnosed with metabolic obesity and attended the Metabolic Obesity clinic at Hospital Pengajar UPM for the past one year. Body composition was assessed using Body Composition Analyzer (SECA, Hamburg, Germany). The data included weight, height, BMI, waist circumference, fat mass, fat-free mass, skeletal muscle mass, visceral adipose tissue, resting energy expenditure, and total energy expenditure. A total of 34 complete patient’s records were obtained (Age = 43.12 ± 11.6 years, Female = 70.6%, Body Mass Index = 41.20 ± 8.6 kg/m2) for the past one year with a mean duration of follow-up visits of 4.5 ± 3.4 months. About 47.1% of the patients had a BMI of more than 40 kg/m2. Following the MNT, BMI (39.9 ± 7.1 kg/m2 vs. 39.2 ± 7.3 kg/m2), waist circumference (112.56 ± 16.03cm vs. 106.68 ± 16.30cm), visceral adipose tissue (4.99 ± 2.81 to 4.17 ± 2.66), proportion of fat mass (48.13 ± 7.43% vs 47.38 ± 7.21%), and resting energy expenditure (1847.76 ± 335.77 to 1820.88 ± 332.54 kcal/day; p< 0.001) reduced significantly (p<0.05). Meanwhile, the proportion of fat-free mass (51.92 ± 7.62 vs 52.66 ± 7.19%; p<0.05) increased significantly. No significant change in total energy expenditure (2213.62 ± 446.47 vs 2254.35 ± 454.33 kcal/day) and skeletal muscle mass (25.03 ± 6.63 vs 24.93 ± 6.5 kg) were observed. This study shows that the fat mass is significantly reduced while the skeletal muscle mass is maintained. The proportion of total energy expenditure has no significant change after MNT, which is another reason the patients lose fat mass instead of muscle mass. This would be very important to maintain the weight of patients after MNT. This can cause the metabolism rate to be maintained. MNT is effective in weight management by maximizing fat mass reduction while maintaining muscle mass. It is also very effective in keeping patients' weight constant after weight loss. The role of specific nutrients as part of MNT prescriptions on body composition warrants future investigation
