Beneficial effects of exercise: shifting the focus from body weight to other markers of health
British Journal of Sports Medicine 2009;43:924-927
These data demonstrate that significant and meaningful health benefits can be achieved even in the presence of lower-than-expected exercise-induced weight loss. A less successful reduction in body weight does not undermine the beneficial effects of aerobic exercise. From a public health perspective, exercise should be encouraged and the emphasis on weight loss reduced.

Potential strategies to improve uptake of exercise interventions in non-alcoholic fatty liver disease
Journal of Hepatology Article in Press, Corrected Proof –
The management of non-alcoholic liver disease (NAFLD) concerns lifestyle modification and exercise; however, adherence is poor. Factors such as lack of confidence to exercise, poor understanding of the benefits of exercise, and a fear of falling all influence engagement in physical activity.

There is no action (except abstaining from smoking) that could improve health more than being physically active, yet it remains an afterthought in clinical medicine and federal funding priorities. We continue excitably to search for health in a pill, yet we already have the readily available behavior of regular exercise that would provide enormous benefits.….

The authors' conclusions about the evidence of benefits of exercise interventions were based on the results of small RCTs and some non-randomised trials. Although the results of the trials showed benefits of exercise in the workplace, the conduct of the majority of the trials makes it difficult to draw firm conclusions about the effectiveness of these interventions.
