The purpose of the present study was to evaluate the effects of maternal protein and energy restriction during lactation on the bodyweight and skull dimensions of pups at weaning. At parturition, Wistar rat dams were randomly assigned to the following groups: (i) control group (C), free access to a standard laboratory diet containing 23% protein; (ii) protein-energy-restricted group (PER), free...

Objective: Melanocortin-4 receptor (MC4R) and agouti-related peptide (AgRP) are involved in energy homeostasis in the rat. The aim of the present study was to evaluate the expression of MC4R and AgRP mRNAs in arcuate nucleus (ARC) during long term malnutrition of female ovariectomized rats. Materials and Methods: Ten female ovariectomized rats were divided into two equal groups (n=6) of normal ...

BACKGROUND It is unclear from the inconsistent epidemiologic evidence whether dietary fat intake is associated with future weight change. OBJECTIVE The objective was to assess the association between the amount and type of dietary fat and subsequent weight change (follow-up weight minus baseline weight divided by duration of follow-up). DESIGN We analyzed data from 89,432 men and women from...

This study aimed to investigate the effects of interval and continuous training on the body mass gain and adiposity levels of rats fed a high-fat diet. Forty-eight male Sprague-Dawley rats were randomly divided into two groups, standard diet and high-fat diet, and received their respective diets for a period of four weeks without exercise stimuli. After this period, the animals were randomly di...

OBJECTIVES Obesity is the consequence of an imbalance between energy intake and expenditure, food intake being affected by multiple factors -psychological, social, work-related, etc. This revision discusses the role of diet in the behavioural treatment (BT) of obesity, which faces multiple approaches and focuses on patients' behaviour rather than their mere energy intake. SETTING Recent liter...

BACKGROUND Nutritional studies focus on traditional cultural models and lifestyles in different countries. The aim of this study was to examine the adherence to the Mediterranean diet, life habits, and risk factors associated with cardiovascular diseases among people living in different geographical regions in Spain. METHODS A descriptive cross-sectional study was conducted in each region. Th...

BACKGROUND/AIMS The offspring and grandoffspring of female rats fed low protein diets during pregnancy and lactation, but fed nutritionally adequate diets thereafter, have been shown to exhibit altered insulin sensitivity in adulthood. The current study investigates the insulin sensitivity of the offspring and grandoffspring of female rats fed low protein diets during pregnancy, and then mainta...
