We argue that despite inconsistencies in the definition , patterns across studies clearly show that healthy obesity is a state of intermediate disease risk .
Expert commentary : Given the current state of population -level evidence , we conclude that obesity and metabolic dysfunction are inseparable and that healthy obesity is best viewed only as a state of relative health but not of absolute health .
INTRODUCTION Obesity is a top public health priority but interventions to reverse the condition have had limited success .
About one-in-three obese adults are free of metabolic risk factor clustering and are considered ' healthy ' , and much attention has focused on the implication s of this state for obesity management .
Assessing Causality in the Association between Child Adiposity and Physical Activity Levels: A Mendelian Randomization Analysis
Here , Timpson and colleagues performed a Mendelian R and omization analysis to determine whether childhood adiposity causally influences levels of  physical activity .  The results suggest that increased adiposity causes a reduction in physical activity  in children ; however , this study does not exclude lower physical activity also leading to increasing adiposity .
