Calorie restriction (CR) is the most effective way to increase life span and delay the onset of age-related symptoms in animals. We have previously reported that CR affects a variety of physiological phenotypes in flies and results in dramatic behavioral, physical and demographic changes. Here we show effects of low and high calorie levels on the spontaneous physical activity of flies. Wild typ...

In this paper, we propose a novel walking route navigation system for fitness walkers effective for health maintenance. Recently, lifestyle-related disease has been increasing in the world. It is important for people to keep balance between the calorie intake and the calorie consumption. We focus on calorie consumption by walking, because walking is on effective exercise for maintaining and pro...

BACKGROUND Although the Health & Fitness category of the Apple App Store features hundreds of calorie counting apps, the extent to which popular calorie counting apps include health behavior theory is unknown. OBJECTIVE This study evaluates the presence of health behavior theory in calorie counting apps. METHODS Data for this study came from an extensive content analysis of the 10 most popu...

Calorie values for a wide biological selection of nematodes, determined with a microbomb calorimeter, ranged from 3.86 to 6.85 Kcal/g. The mean of 5.095 Kcal from 16 species was lower than means recorded in three previous studies of other invertebrate groups. The nematode values were skewed to the lowest limit. Larvae of Ditylenchus dipsaci showed lower calorie values after storage, and the cal...

OBJECTIVE Offering calories on restaurant websites might be particularly important for consumer meal planning, but the availability of and ease of accessing this information are unknown. METHODS We assessed websites for the top 100 U.S. chain restaurants to determine the availability of and ease of access to calorie information as well as website design characteristics. We also examined poten...

BACKGROUND A constant preoccupation with food and restrictive eating are main symptoms of anorexia nervosa (AN). Imaging studies revealed aberrant neural activation patterns in brain regions processing hedonic and reward reactions as well as-potentially aversive-emotions. An imbalance between so called "bottom-up" and "top-down" control areas is discussed. The present study is focusing on neura...

The authors provide evidence that social ethics claims on food packaging (e.g., fair trade) can promote the misperception that foods are lower-calorie and therefore appropriate for greater consumption. In Study 1, participants evaluating chocolate provided lower calorie judgments when it was described as fair trade—a claim silent on calorie content but signifying that trading partners received ...

In a field experiment involving online workplace lunch orders, this study examines the impact of numeric and traffic light calorie labels on calorie intake. Employees of a large corporation ordered lunches through a website of the authors’ design, on which they were presented menus with numeric calorie labels, traffic light labels, or both together, and the authors compared the calorie content ...

Why is America a land of low-calorie food claims yet high-calorie food intake? Four studies show that people are more likely to underestimate the caloric content of main dishes and to choose higher-calorie side dishes, drinks, or desserts when fast-food restaurants claim to be healthy (e.g., Subway) compared to when they do not (e.g., McDonald’s). We also find that the effect of these health ha...
