In the United Kingdom more than 25% of adults are classified as clinically obese, thus leading to a normalisation of overweight and obesity. As being 'plus size' becomes more common, there is an increase in weight status misperception that can potentially undermine the recognition of being overweight and its health consequences. The aim of this study was to explore the trends and socio-demographic factors underlying perceived weight status among the overweight or obese population in England. A cross-sectional study was done to collect data through face-to-face interviews and a self-completion questionnaire. The findings of this study showed that there is an increasing trend in misperceiving weight status between both men and women. The authors’ conclude this is possibly reflective of the normalisation of overweight and obesity and that it is vital for obesity prevention programs to consider socioeconomic inequalities for program effectiveness.
Abstract
OBJECTIVE This study aimed to investigate trends and sociodemographic factors underlying weight misperception in adults with overweight and obesity in England. METHODS This study used descriptive and logistic regression analyses based on a pooled nationally representative cross-sectional survey, Health Survey for England, for the years 1997, 1998, 2002, 2014, and 2015 of individuals with BMI ≥ 25 (n = 23,459). The main outcomes were (1) weight misperception and (2) weight-loss attempts as well as the associations with demographic and socioeconomic characteristics and health status. RESULTS The proportion of individuals with overweight and obesity misperceiving their weight status increased over time between 1997 and 2015 (37% to 40% in men; 17% to 19% in women). There were socioeconomic disparities in the misperception of weight status, with lower-educated individuals from poorer-income households and members of minority ethnic groups being more likely to underestimate their weight. Those underestimating their overweight and obesity status were 85% less likely to try to lose weight compared with people who accurately identified their weight status. CONCLUSIONS The upward trend in underassessment of overweight and obesity status in England is possibly a result of the normalization of overweight and obesity. Obesity prevention programs need to consider differential sociodemographic characteristics associated with underassessment of weight status.

Regular consumption of nuts has been associated with healthy changes in blood cholesterol despite the fact that nuts are energy dense and high in fat. The aim of this parallel study was to assess the effects of various, equally dense snacks on body weight and composition, blood lipids, resting metabolic rate, appetite indices and dietary quality in 118 adults. Participants consumed daily portions of hazelnuts, chocolate or potato crisps compared to a control group receiving no snacks for 12 weeks. This study found that after 12 weeks, dietary quality improved significantly in the nut group, and no other outcome measurements were significantly different. Based on these results, the authors conclude that public health policy should continue to encourage regular consumption of nuts among the population promoting cardio-protective effects without weight gain.
Abstract
Previous studies have reported that regular nut consumption reduces cardiovascular disease (CVD) risk and does not promote weight gain despite the fact that nuts are energy-dense. However, no studies have investigated the body composition of those regularly consuming nuts compared to similar intakes of other snacks of equal energy density. This parallel study (n = 118) examined the effects of providing daily portions (~1100 kJ/d) of hazelnuts, chocolate, or potato crisps compared to a control group receiving no snacks for twelve weeks. Effects on body weight and composition, blood lipids and lipoproteins, resting metabolic rate (RMR), appetite indices, and dietary quality were compared. At week 12, there was no significant difference in any of the outcome measurements between the groups except for dietary quality, which improved significantly in the nut group. Nuts can be incorporated into the diet without adversely affecting body weight and can improve diet quality.
