Energy restriction extends life span and lowers mortality from age-related diseases in many species, but the effects in humans are unknown. We prospectively examined this relationship in a large epidemiological study of Japanese-American men. We followed 1915 healthy nonsmokers, aged 45-68 years at study onset, for 36 years. Twenty-four-hour recall of diet was recorded at baseline, and follow-u...

The objective of the study was to describe the food intake of adventure racers during a competition simulated in the laboratory. Ten male athletes with international experience in adventure races took part in the study. The experiment lasted 67 hr (total distance covered 477.3 km), but 3 athletes did not finish the race. Food intake was recorded throughout the simulation. Athletes' total energy...

BACKGROUND Energy intake is a key determinant of weight. OBJECTIVE Our objective was to examine trends in energy intake in adults in the United States from 1971-1975 to 2009-2010. DESIGN The study was a trend analysis of 9 national surveys in the United States that included data from 63,761 adults aged 20-74 y. RESULTS Adjusted mean energy intake increased from 1955 kcal/d during 1971-197...

Background & Aims: Unhealthy snacks contain high amounts of calories, simple sugars, fat, cholesterol, salt, additives, and conservatives. Increased consumption of these unhealthy snacks is one of the underlying factors for the prevalence of overweight, obesity, and metabolic disorders. In this study, we investigated the effects of unhealthy snacks on diet and the risk of metabolic syndrome aft...

Animals have to adjust their activities when faced with caloric restriction (CR) to deal with reduced energy intake. If CR is pronounced, allostasis can push individuals into alternate physiological states which can result in important health benefits across a wide range of taxa. Here we developed a new approach to determine the changes in behavioural phenotype associated with different levels ...

The epidemics of obesity and diabetes have aroused great interest in the analysis of energy balance, with the use of organisms ranging from nematode worms to humans. Although generating energy-intake or -expenditure data is relatively straightforward, the most appropriate way to analyse the data has been an issue of contention for many decades. In the last few years, a consensus has been reache...

Obesity has become, nowadays, a global concern affecting both developed and developing countries. Nutrition and physical activity represent the major factors influencing energy balance and subsequently weight status. Deciding toward an appropriate intake of all nutrients is seen as necessary to maintain a wholesome lifestyle: among nutrients, sugar plays a major role and its consumption has lon...

In this descriptive cross-sectional study 14 national basketball team players attending the preparatory camp for the Asian games with mean age of 25. 6 ± 3.1 yrs, height of 191 ± 6 em,w eight of87.3 ±8 .1 kg and BMI of 23.9 ±1.7 were surveyed. The subjects underwent anthropometlic, aerobic power, body fat content and V02max measurements in three stages of the training period (before train...

the study was carried out on 120 crossbred holstein × shahiwal dairy cows for a period of 150 days to quantify the influence of dietary energy and protein intake on yield and composition of milk. total 12 dairy farms having similar housing systems and holding at least 20 dairy cows in between mid to late lactation were selected for study purposes. the farms were located in the peri-urban and ur...

BACKGROUND Olive oil is an energy-dense food frequently consumed in south European countries with increasingly high obesity prevalence. Evidence of the impact of olive oil consumption on BMI and the risk of obesity is limited. We analyzed this association taking into consideration the problem of energy underreporting. METHODS Cross-sectional data on 6,352 Spanish adults were analyzed. Dietary...
