Abstract
Obesity is linked with metabolic abnormalities such as insulin resistance and hyperglycemia, which improve upon weight loss. However, achieving and sustaining meaningful weight loss is hard for a majority of the free-living population. Perhaps, strategies that do not require weight loss may offer a more practicable approach. In fact, improvement in glycemic control may also be achieved by adipose tissue expansion under specific circumstances. Several animal models show a significant enhancement of glycemic control, if adipose tissue is expanded transgenically or by stimulating adipogenesis. In humans, considerable evidence, including the action of thiazolidinedione class of drugs, indicates that adipose tissue expandability is associated with an improved metabolic profile. Admittedly, iatrogenic weight gain to improve diabetes may be socially and cosmetically undesirable and inappropriate for some other obesity-associated comorbidities. Therefore, it is less practical to promote adipogenesis as a measure to improve glycemic control. Nonetheless, this approach has provided templates and targets for future research. Indications are that further research may creatively uncouple the adipogenic and antiglycemic effects to improve obesity-associated metabolic abnormalities independent of weight loss.
