Dietary restriction (DR) extends life span in diverse organisms, including mammals, and common mechanisms may be at work. DR is often known as calorie restriction, because it has been suggested that reduction of calories, rather than of particular nutrients in the diet, mediates extension of life span in rodents. We here demonstrate that extension of life span by DR in Drosophila is not attribu...

Computer vision has been introduced to estimate calories from food images. But current food image datasets dont contain volume and mass records of foods, which leads to an incomplete calorie estimation. In this paper, we present a novel food image dataset with volume and mass records of foods, and a deep learning method for food detection, to make a complete calorie estimation. Our dataset incl...

Calorie restriction (CR), or caloric restriction, or energy restriction, is a dietary regimen that reduces calorie intake without incurring malnutrition or a reduction in essential nutrients. "Low" can be defined relative to the subject's previous intake before intentionally restricting calories, or relative to an average person of similar body type. Calorie restriction without malnutrition has...

Background and aims: It is well known that dyslipidemia is related to cardiovascular disease, dietary aspect and obesity play an important role in CVD risk factor. In the present study, we investigated the relationship between calorie intake, anthropometrical parameters and serum lipids in apparently healthy women. Methods: The subject were 90 healthy wom...

This paper proposes a finite mixture model (FMM) to model the behavioral transition of calorie consumption with an assumption that nutrition consumption is a mixture of two different behavioral stages: a poor stage and an affluent stage. Based on 387 calorie-income elasticities collected from 90 primary studies, our results identify that the threshold income for calorie demand transition is 459...

Introduction University College London Hospital (UCLH) was one of the largest contributors to the CALORIES trial; a pragmatic, multi-centre, randomised control trial examining the effectiveness of early nutritional support in critically ill patients through a comparison of parenteral and enteral nutrition. The trial found no significant difference in 30-day mortality associated with the route o...

Calorie restriction has been regarded as the only experimental regimen that can effectively lengthen lifespan in various animal models, but the actual mechanism remains controversial. The gut microbiota has been shown to have a pivotal role in host health, and its structure is mostly shaped by diet. Here we show that life-long calorie restriction on both high-fat or low-fat diet, but not volunt...

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...
