Metabolically Healthy Obesity is not a Myth: A Case Report

Project description:People with obesity who do not have the metabolic syndrome or components of the metabolic syndrome have been characterized as having metabolically healthy obesity (MHO). However, the existence of MHO has been questioned because people with MHO are at greater risk of developing diabetes and fatal cardiovascular disease than people who are lean and healthy. A 25 year-old woman with rigorously defined MHO (based on normal oral glucose tolerance, insulin sensitivity (assessed by using the hyperinsulinemic-euglycemic clamp procedure), plasma triglyceride and HDL-cholesterol, intrahepatic triglyceride content and carotid intima-media thickness [CIMT]) was evaluated at baseline (BMI=37.7 kg/m2) and 5 years later, after gaining 30.8 kg (32%) in weight (BMI=49.6 kg/m2). The increase in weight was comprised of an 8.8 kg (20%) increase in FFM, 22.0 kg (42%) increase in total body fat, 8.1 kg (37%) increase in leg fat mass, 57% increase in subcutaneous abdominal fat and a 78% in intra-abdominal fat. Weight gain did not have adverse effects on fasting plasma glucose, oral glucose tolerance, beta-cell function, insulin sensitivity, plasma triglyceride, intrahepatic triglyceride content and CIMT. Adipose tissue expression of genes involved in extracellular matrix formation did not change. Adipose tissue expression of several inflammation-related genes increased by more than 30%, but was not associated with a corresponding increase in plasma cytokine concentrations, with the exception of an increase in plasma IL-6. The present case study demonstrates that some people with obesity are resistant to the adverse cardiometabolic effects of excess adiposity and marked weight gain.

Transient dietary intervention induces healthy adipose tissue expansion and metabolically healthy obesity in mice

Project description:As obesity progresses, dynamic tissue remodeling of adipose tissue occurs over time, i.e., adipocyte hypertrophy, chronic inflammation, and interstitial fibrosis. Some obese individuals exhibit healthy adipose tissue expansion, characterized by modest inflammation and fibrosis despite adipocyte hypertrophy, resulting in “Metabolically Healthy Obesity (MHO)”. Our research has revealed that MHO can be induced by temporary weight loss during the development of obesity.

Cardiometabolic characteristics of people with metabolically healthy and unhealthy obesity [ThighMuscle]

Project description:Some people with obesity are resistant to the adverse metabolic effects of excess adiposity and are considered to have “metabolically healthy obesity” (MHO). However, the mechanisms responsible for MHO are not clear. We performed comprehensive cardiometabolic profiling in 20 adults with MHO (defined by features of normal insulin sensitivity), 20 age-, sex-, and BMI-matched adults with metabolically unhealthy obesity (MUO), and 15 adults who were metabolically healthy and lean (MHL). More than 120 variables were evaluated, including body composition, beta-cell function, 24-hour plasma metabolic profile, rates of de novo lipogenesis and cholesterol synthesis, plasma adipokine concentrations, oxidative stress, plasma lipoprotein profiles, cardiovascular structure/function, skeletal muscle bioactive lipids, and both adipose tissue and skeletal muscle transcriptomics. Using dimensionality reduction approaches, measures of insulinemia and skeletal muscle ceramides were the strongest discriminators of MHO and MUO status. These data clarify the characteristics associated with preserved metabolic health in response to obesity.
