The Associations of Resting Metabolic Rate with Chronic Conditions and Weight Loss

Body weight is positively associated with RMR. However, there exists a paucity of research on the associations between baseline and changes in resting metabolic rate (RMR) with chronic conditions and weight loss (WL), with findings being inconsistent. Sex stratified analysis was undertaken. Despite having a significant WL of 6.2 8.5 kg (P<0.05), there were no significant RMR (16 325 kcal/day, P > 0.05). Men and women with high blood pressure had higher baseline RMR, and only women with high LDL had lower baseline RMR than those without the respective chronic condition (P<0.05). Regardless of sex, WL was not significantly associated with baseline RMR or RMR (P>0.05). This study suggests that participants with a low baseline RMR do not appear to be at a disadvantage for WL. Further, WL can occur without reductions in RMR in individuals with high levels of obesity and obesity-related comorbidities.
