INTRODUCTION: This study explores what types of information obese individuals search for on the Internet, their motivations for seeking information and how they apply it in their daily lives. METHOD: In-depth telephone interviews with an Australian community sample of 142 individuals with a BMI ≥ 30 were conducted. Theoretical, purposive and strategic samplings were employed. Data were analysed using a constant comparative method. RESULTS: Of the 142 individuals who participated in the study, 111 (78%) searched for information about weight loss or obesity. Of these, about three quarters searched for weight loss solutions. The higher the individual's weight, the more they appeared to search for weight loss solutions. Participants also searched for information about health risks associated with obesity (n = 28), how to prevent poor health outcomes (n = 30) and for peer support forums with other obese individuals (n = 25). Whilst participants visited a range of websites, including government-sponsored sites, community groups and weight loss companies, they overwhelmingly acted upon the advice given on commercial diet websites. However, safe, non-judgemental spaces such as the Fatosphere (online fat acceptance community) provided much needed solidarity and support. CONCLUSIONS: The Internet provides a convenient source of support and information for obese individuals. However, many turn to the same unsuccessful solutions online (e.g. fad dieting) they turn to in the community. Government and community organisations could draw upon some lessons learned in other consumer-driven online spaces (e.g. the Fatosphere) to provide supportive environments for obese individuals that resonate with their health and social experiences, and address their needs.

Obese adults face pervasive and repeated weight-based stigma. Few researchers have explored how obese individuals proactively respond to stigma outside of a dominant weight-loss framework. Using a grounded theory approach, we explored the experiences of 44 bloggers within the Fatosphere--an online fat-acceptance community. We investigated participants' pathways into the Fatosphere, how they responded to and interacted with stigma, and how they described the impact of fat acceptance on their health and well-being. The concepts and support associated with the fat-acceptance movement helped participants shift from reactive strategies in responding to stigma (conforming to dominant discourses through weight loss) to proactive responses to resist stigma (reframing "fat" and self-acceptance). Participants perceived that blogging within the Fatosphere led them to feel more empowered. Participants also described the benefits of belonging to a supportive community, and improvements in their health and well-being. The Fatosphere provides an alternative pathway for obese individuals to counter and cope with weight-based stigma.

© The Author(s) 2013. This article contributes to scholarship on the cultural politics of obesity by providing insights into how people considered ‘obese’ think news media reporting should be improved and their views on ideas such as reporting guidelines and promoting body diversity. A thematic analysis of interview data identified the following themes: ‘Challenging stereotypes’, ‘The limits of news’, ‘Individual responsibility’ and ‘Legitimating fat’. These themes capture the divergence in views and reflect differences in how people construct obesity and conceive the influences of media on audiences. Situated in the context of the contested science and news frames surrounding obesity, the analysis also engages with wider debates about the potentially unintended consequences of seeking to challenge stigma. We conclude that media and policy discourses need to reflect a diversity of ways of framing obesity if the views of obese people are to be included.

The news media plays an important role in making visible and shaping public understandings of health and health risks. In relation to overweight and obesity, it has been suggested that the media is more likely to engage in alarmist reporting in a climate in which it is taken for granted that obesity is an 'epidemic'. This study analyses Australian media coverage of a report on overweight and obesity, Australia's Future 'Fat Bomb': a report on the long-term consequences of Australia's expanding waistline on cardiovascular disease, by one of Australia's leading health and medical research institutes. Our study found that the report was consistently framed across media outlets as showing that Australia is the 'fattest nation' in the world, having overtaken the Americans. This is despite the fact that the Fat Bomb study did not include international comparisons and was based only on data from middle-aged Australians. Because reports of increasing rates of obesity had already been widely covered in the media, the press needed to find a new way of signifying the problem, which was provided by comments made by its lead author in publicising the report. Consistent with previous research, there was a notable absence of critical commentary on the study and a failure to test the claims of its lead author. We conclude that this reporting could have contributed to a policy environment in which the perceived threat of obesity is deemed to be so great that efforts to contain it may be subjected to less scrutiny than they warrant. © 2011 Taylor & Francis.

An experiment was conducted with barramundi (Lates calcarifer) juveniles to examine the marginal efficiency of utilisation of long chain-polyunsaturated fatty acids (LC-PUFA). A series of five diets with blends of fish (anchovy) oil and poultry fat (F100:P0, F60:P40, F30:P70, F15:P85, F0:P100) were fed to 208. ±. 4.1. g fish over a 12-week period. The replacement of fish oil with poultry fat had no impact on growth performance (average final weight of 548.3. ±. 10.2. g) or feed conversion (mean = 1.14. ±. 0.02). Analysis of the whole body composition showed that the fatty acid profile reflected that of the fed diet. However it was also shown that there was a disproportional retention of some fatty acids relative to others (notably LOA, 18:2n-6 and LNA, 18:3n-3). By examining the body mass independent retention of different fatty acids with differential levels of intake of each, the marginal efficiencies of the use of these nutrients by this species were able to be determined. The differential retention of fatty acids in the meat was also examined allowing the determination of oil blending strategies to optimise meat n-3 LC-PUFA levels.

Whilst there have been many studies in various species examining the effects of leptin on food intake, there is a paucity of data comparing responsiveness in the two sexes. We have, therefore, addressed this issue in sheep. Because this species shows seasonal variation in voluntary food intake (VFI), we also considered the possibility that there might be seasonal variation in the responsivity to leptin. Centrally administered leptin was relatively ineffective as a satiety factor in either sex during AUTUMN: In Spring, leptin had a profound inhibitory effect on VFI in the females, but only a slight effect in males. These data indicate that responsiveness to leptin depends on sex and also on season in animals that are substantially affected by photoperiod.

Protein kinase R (PKR) has previously been suggested to mediate many of the deleterious consequences of a high-fat diet (HFD). However, previous studies have observed substantial phenotypic variability when examining the metabolic consequences of PKR deletion. Accordingly, herein, we have re-examined the role of PKR in the development of obesity and its associated metabolic complications in vivo as well as its putative lipid-sensing role in vitro. Here we show that the deletion of PKR does not affect HFD-induced obesity, hepatic steatosis or glucose metabolism, and only modestly affects adipose tissue inflammation. Treatment with the saturated fatty acid palmitate in vitro induced comparable levels of inflammation in WT and PKR KO macrophages, demonstrating that PKR is not necessary for the sensing of pro-inflammatory lipids. These results challenge the proposed role for PKR in obesity, its associated metabolic complications and its role in lipid-induced inflammation.
