The operative definition of sarcopenic obesity is still under discussion and creates difficulties in clinical practice. Muscle weakness, rather than low muscle mass, was previously proposed as an alternative criterion and, more recently, the dynapenic abdominal obese phenotype is of increasing interest because of its unfavorable health consequences and usability in clinical practice. Recent findings This review focuses on the most recent findings of pathogenic inter-relationships between adipose tissue and muscle. Recent studies on health consequences of sarcopenic obesity and dynapenic abdominal obesity are also examined. Despite the lack of consensus on a definition for sarcopenic obesity, progress has been made in the delineation of the treatment principles for this condition. Summary Further research is needed to compare different definitions of sarcopenic/dynapenic obesity to clarify the relationship between obesity and the most important adverse outcomes in the elderly. The next step will be the definition of best possible therapeutic approaches for this condition. Copyright © 2019 Wolters Kluwer Health, Inc. All rights reserved.
