1. Groups of lean and genetically obese (ob/ob) mice were adapted to varying energy intakes and the rates of total protein turnover in liver, gut and kidney were measured. 2. Lean mice gained less weight when fed above maintenance and lost less weight when fed below maintance than obese mice. 3. Hepatic protein turnover (mg/d) was sigmoidally related to digestible energy intake in lean mice but...

Human-robot interaction research is maturing to the point where we can begin to build systems that interact with people in their daily lives and provide support for particular needs. We propose that sociable robot systems are systems that comprise a sociable robot, other technological devices, methods for interaction, and methods for relationship creation and maintenance. These systems can be d...

BACKGROUND: We have previously reported that a fat-reduced high-protein diet had more favourable effects on body weight loss over 6 months than a medium-protein diet. OBJECTIVE: To extend this observation by a further 6–12 months less stringent intervention and a 24 months follow-up. DESIGN: A randomised 6 months strictly controlled dietary intervention followed by 6–12 months dietary counselli...

BACKGROUND Medical events are often reported as triggers for weight loss, but it is unknown whether medical triggers result in better short- and long-term weight control. METHODS The relationship between medical triggers and weight loss was examined in the National Weight Control Registry (NWCR), a database of individuals who have lost > or =30 lbs and kept it off for > or =1 year. Recall of ...

OBJECTIVE To analyze the determinants for weight loss (> 5%) resulting from outpatient individual appointments. SUBJECTS AND METHODS A retrospective cohort study was conduct in 318 overweight/obese patients seeking individual care to lose weight. RESULTS Fifteen percent of the patients did not lose weight; 35.1% had lost < 5%; 35.4% had lost between 5 and 10%; and 13.9% had lost > 10%. Pati...

BACKGROUND Effective approaches are needed to address the increasing prevalence of overweight and obesity. The present study investigated whether all meal provision was a more effective and acceptable method for weight loss than a self-directed diet. METHODS This randomised controlled trial recruited 112 men and women with a body mass index in the range 27-35 kg m(-2), who had no comorbiditie...

AIM The purpose of this study was to identify psychosocial determinants for maintaining weight loss. METHODS 42 obese individuals who achieved a 12% weight loss before entering a 52-week weight maintenance program were interviewed qualitatively. Psychosocial factors related to weight loss maintenance were identified in two contrasting groups: weight reducers and weight regainers. Groups were ...

OBJECTIVE The aim of this study was to determine whether providing information about the lifestyle changes required for an individual to lose weight following bariatric surgery would mitigate the negative judgments of that individual. METHODS In an experimental design, participants provided their initial impressions of a woman with obesity before learning that she had lost a significant amoun...

Background Obesity continues to be a serious public health challenge. Rates are increasing worldwide, with nearly 70% of the US adults overweight or obese, leading to increased clinical and economic burden. While successful approaches for achieving weight loss have been identified, techniques for long-term maintenance of initial weight loss have largely been unsuccessful. Financial incentive in...
