“Overall, body attractiveness was a better predictor of self-reported mating success than facial attractiveness. In line with our main hypothesis, we found a positive relationship between a composite measure of men’s physical fitness (PF) and men’s body attractiveness. This was obtained not only for aggregated attractiveness ratings but also for all 27 female raters individually. This finding is remarkable because individual attractiveness judgments reflect a strong idiosyncratic component, at least for faces. Attractiveness judgments were made fast and effortless. The strength of the attractiveness-fitness relation- ship obtained here suggests that signalling physical fitness may be one of the key functions of male attractiveness.”
Dietary restriction is an effective strategy for weight loss in obese individuals. The most common form of dietary restriction implemented is daily calorie restriction (CR), which involves reducing energy by 15-60% of usual caloric intake every day. Another form of dietary restriction employed is intermittent CR, which involves 24 h of ad libitum food consumption alternated with 24 h of complete or partial food restriction. Although both diets are effective for weight loss, it remains unknown whether one of these interventions produces superior changes in body weight and body composition when compared to the other. Accordingly, this review examines the effects of daily CR versus intermittent CR on weight loss, fat mass loss and lean mass retention in overweight and obese adults. Results reveal similar weight loss and fat mass loss with 3 to 12 weeks' intermittent CR (4-8%, 11-16%, respectively) and daily CR (5-8%, 10-20%, respectively). In contrast, less fat free mass was lost in response to intermittent CR versus daily CR. These findings suggest that these diets are equally as effective in decreasing body weight and fat mass, although intermittent CR may be more effective for the retention of lean mass.
