INTRODUCTION Obesity is a growing epidemic fuelled by unhealthy behaviours and associated with significant comorbidities and financial costs. While behavioural interventions produce clinically meaningful weight loss, weight loss maintenance is challenging. This may partially be due to failure to target stress and emotional reactivity. Mindfulness-based stress reduction (MBSR) reduces stress and...

OBJECTIVE The safety and efficacy of IQP-PV-101, a proprietary extract of Phaseolus vulgaris, on weight management in two phases was evaluated here. The weight loss (WL) phase was conducted over 12 weeks and the weight maintenance (WM) phase took 24 weeks. METHODS In the double-blind WL phase, subjects were randomized to receive either IQP-PV-101 or placebo. All subjects adhered to a mildly h...

OBJECTIVE The aim of this cross-sectional study was to evaluate prevalence of and strategies behind low/no calorie sweetened beverage (LNCSB) consumption in successful weight loss maintainers. METHODS An online survey was administered to 434 members of the National Weight Control Registry (NWCR, individuals who have lost ≥13.6 kg and maintained weight loss for > 1 year). RESULTS While few p...

OBJECTIVE To investigate the efficacy of orlistat on the maintenance of weight loss over 3 years following a major weight loss induced by very-low-energy diet (VLED) in obese patients with metabolic risk factors such as dyslipidemia, impaired fasting glucose, and diet-treated type 2 diabetes. RESEARCH DESIGN AND METHODS Initially, weight loss was induced by an 8-week VLED (600-800 kcal/day) i...

Weight rebound after successful weight loss is a well-known phenomenon in humans and dogs, possibly due to the fact that energy restriction improves metabolic efficiency, reducing post-weight-loss maintenance energy requirements (MER). The aim of the present study was to estimate post-weight-loss MER in obese pet dogs that had successfully lost weight and did not subsequently rebound. A total o...

The case is reported of a 5 year old boy who was pressured to lose weight in order to wrestle at a lower weight class. Although a minority of athletes engage in unhealthy weight management practices, this is an unusual case because of the age of the athlete and the influential role of a parent.

We propose a nonparametric Bayesian approach to estimate the natural direct and indirect effects through a mediator in the setting of a continuous mediator and a binary response. Several conditional independence assumptions are introduced (with corresponding sensitivity parameters) to make these effects identifiable from the observed data. We suggest strategies for eliciting sensitivity paramet...
