Sources of variation in nutrient intake have been examined for Western diets, but little is known about the sources of variation and their differences by age and sex among Koreans. We examined sources of variation in nutrient intake and calculated the number of days needed to estimate usual intake using 12 d of dietary records (DR). To this end, four 3 d DR including two weekdays and one weeken...

Calorie restriction (CR), which usually refers to a 20-40% reduction in calorie intake, can effectively prolong lifespan preventing most age-associated diseases in several species. However, recent data from both human and nonhumans point to the ratio of macronutrients rather than the caloric intake as a major regulator of both lifespan and health-span. In addition, specific components of the di...

OBJECTIVE To examine the utility of using external estimates of within-person variation to adjust usual nutrient intake distributions. DESIGN Analyses of the prevalence of inadequate intake of an example nutrient by the Estimated Average Requirement (EAR) cut-point method using three different methods of statistical adjustment of the usual intake distribution of a single 24-hour recall in Rus...

Background and Objective: Recent studies have shown a relationship between energy regulation and the circadian rhythm at behavioral, molecular, and physiological levels. The present study investigated the effect of chronotype on meal timing and obesity in Iranian housewives. Materials and Methods: This cross-sectional study was carried out using a convenience-sampling method through the partic...

Introduction: It is estimated that by 2020, non communicable diseases will account for approximately twothird of all diseases that are often related to life style and nutrition. This study was conducted to assess Food pattern and anthropometric indices of students in Kerman University of Medical Sciences. Methods: In this cross-sectional study, 375 students (225 females, 150 males) with mean ag...

BACKGROUND Malfunction in the energy homeostasis system is a major cause of developing obesity. Melanocortin-4 receptor (MC4R) plays a crucial role in this system as a key receptor. Although MC4R gene as an obesity candidate gene is associated with higher BMI, only few attempts have been carried out to understand the mechanism underlying body-weight regulation. OBJECTIVE The aim of this study...
