An evaluation of basal metabolic rate among healthy individuals — a cross-sectional study

Abstract

BackgroundThe main source of daily energy requirement in Asian societies is basal metabolic rate (BMR). Even though the reason for this fluctuation is debatable, prior research have shown that BMR is highly varied in individuals. All studies concur that variation in fat-free mass (FFM) is important, although the effects of fat mass (FM), age, sex, and the hormones leptin, triiodothyronine (T3), and thyroxine (T4) are still unknown.ObjectiveThe main objectives of the study are as follows:• To evaluate the basal metabolic rate among healthy individuals• To identify the risk factors on basal metabolic rate among healthy individualsMethodologyIn total, 50 individuals were consecutively enrolled in the study during the entrepreneurship studio on 29th June 2022 held at Garden City University (GCU). The inclusion criteria were age between 18 and 50 years, both males and females, students and professors of GCU, and healthy individuals. The exclusion criteria were subjects who had overt metabolic and/or endocrine diseases (e.g., diabetes, hypothyroidism, hypertension, amenorrhea) and those taking any drug known to influence energy metabolism. The convenient samples of 50 subjects were taken from this study.Outcome measuresBasal metabolic rate (BMR) and body mass index (BMI).ResultsThe demographic data, height, weight, BMI, and BMR were recorded. The mean and standard deviation of age are 25.81 ± 8.71 and 23.95 ± 6.67 of males and females, respectively. The mean and standard deviation of height are 1.68 ± 0.68 and 1.63 ± 0.07, respectively. The mean and standard deviation for weight are 63.8 ± 11.49 and 54.86 ± 10.43, respectively. The mean and standard deviation of BMI are males and females which are 22.3 ± 3.22 and 20.47 ± 3.62, respectively. The mean and standard deviation of BMR are males and females which are 1552.41 ± 127.3 and 1327.7 ± 147.9.ConclusionThe energy used up while lying still at rest and being awake during the nocturnal postabsorptive state is known as the basal metabolic rate (BMR). The values can be used as a reference for comparison with the normative values, and cardiorespiratory endurance training can be included in the rehabilitation program.
