Two experiments were carried out to examine how spreading food intake between either two or four occasions would affect mood and cognition. The first experiment used 96 participants in a between subject design where participants received either two milkshakes at 09:00 and 13:00 or four (half nutrient content but same volume) milkshakes at 09:00, 11:00, 13:00 and 15:00. The results showed that verbal...
Focus groups (n=65) were conducted with Hmong adults in St. Paul/Minneapolis, MN to determine how environmental factors, acculturation, and food insecurity influence dietary behavior, body mass index (BMI), and health. Acculturation was assessed by examining linguistic, social, and eating behavior, length of time in the US, and BMI for B-TL 1 (born in Thailand/Laos and in US ≤5 years), B-TL...
This paper examines the relationships among reports of depressive symptoms, BMI and frequency of consumption of 30 foods in 4655 middle-aged women. Food was grouped into three categories: high-calorie sweet, high-calorie nonsweet, and low-calorie. Controlling for total energy intake, BMI and depressive symptoms were both inversely associated with a higher frequency of consumption of low-calorie foods...
5-Hydroxytryptamine (5-HT; serotonin) system is the major neurotransmitter system of interest in research on anorexia nervosa (AN). The AN patients show extreme dieting weight loss, hyperactivity and low basal levels of 5-hydroxyindoleacetic acid (5-HIAA), a major metabolite of 5-HT in the cerebrospinal fluid (CSF). Studies on animal models show that diet restriction (DR) decreases 5-HT metabolism...
Breast milk is practically the only food ingested during the first months of life in fully breastfed infants and it is assumed to match the infant's nutritional needs. Epidemiological data suggest that breastfeeding compared with infant formula feeding confers protection against several chronic diseases later on in life and, particularly, against obesity and related medical complications. However,...
This study investigates elementary school children’s prejudice towards obesity. A sample of 1861 underweight, normal, overweight and obese children from Central Greece were instructed to rank 6 drawings of same sex children with various physical disabilities, obesity or no disability at all (“healthy”), according to how much they liked each child. Results showed that all participants ranked the obese...
The purpose of this study was to examine the potential improvements in eating self-efficacy, eating behavior and other psychological factors in obese subjects participating in a weight management program. The participants in this study consisted of 96 persons (76 women and 20 men) who were attending the first session of a commercially run 20-week treatment program for weight reduction. Self-efficacy...
Previously, we have used a ‘method of constant stimuli’ to quantify the satiety that different foods are expected to deliver. Our data indicate that foods differ considerably (some are expected to deliver 5–6 times more satiety than others [per kcal]). In the present study we explored the relative importance of ‘expected satiety’ in decisions about portion size. For eight different snack foods, we...
This study assessed the effect of exercise timing relative to meal consumption on appetite and its hormonal regulators (i.e., PYY 3–36 , ghrelin and leptin) in moderately active young men. Twelve men performed three trials in a random order: (1) meal consumption, (2) exercise 2h after a meal, (3) exercise 1h before a meal. The test meal provided 16.5kcalkg −1 with 70% fat, 26% carbohydrate...
Overeating may be a consequence of the suppression of negative emotions, by depleting self-control resources. This experiment investigated whether (a) there is a causal relationship between the suppression of negative emotions, negative mood, and overeating in people with binge eating disorder (BED) and whether (b) this relationship is increased in depressed people with BED. Sixty-six women with (full...
This study was designed to measure the levels of serum and saliva ghrelin concentrations before and after surgery in an attempt to clarify whether this hormone plays any significant roles in acute appendicitis and cholelithiasis patients when compared with healthy controls. Samples were obtained from 20 patients with appendicitis, 10 patients with cholelithiasis before and after operation, and 16...
The objective of this study was to describe the association between meal pattern and obesity. The study is based on data from the INTERGENE research programme, and the study population consists of randomly selected women and men, aged 25–74, living in the Västra Götaland Region in Sweden. A total of 3610 were examined. Participants with measured BMI≥30 were compared with others (BMI<30) with respect...
To examine how a low-carbohydrate diet affects cognitive performance, women participated in one of two weight-loss diet regimens. Participants self-selected a low-carbohydrate (n=9) or a reduced-calorie balanced diet similar to that recommended by the American Dietetic Association (ADA diet) (n=10). Seventy-two hours before beginning their diets and then 48h, 1, 2, and 3 weeks after starting, participants...
A majority of Americans do not meet the recommendation to eat five servings of fruits and vegetables per day (5-A-Day). The purpose of the present study was to examine the utility of the theory of planned behavior (TPB) for understanding 5-A-Day intentions and behavior and to determine whether any of the TPB relationships were moderated by ethnicity or gender. A total of 413 participants completed...
Rats that are fed cafeteria diet (CD) are a widely used model of obesity. Presenting a varied and energy-dense diet often leads to hyperphagia and weight gain. However, the exact macronutrient composition of ingested food remains difficult to measure accurately. The current investigation aims to improve the accuracy of food intake calculations using a novel compensation for water evaporation, and...
This paper reports findings from a cross-sectional survey carried out in April–May 2006 among international students enrolled at Ghent University in Belgium. The aim of the study was to assess their knowledge and attitudes related to nutrition, perceived changes in dietary habits, perceived barriers to healthy eating and the determinants of dietary changes since their arrival in Belgium. In total,...
The aim of the present study was to test if pleasure, neutrality and disgust expressed by other individuals on a photograph could affect the desire to eat liked or disliked food products. Forty-four men and women were presented with two series of photographs. The first series of photographs was composed of six food photographs: three liked and three disliked food products. The second series consisted...
The purpose of this study was twofold: (1) to determine if gastrointestinal hormones, associated with energy intake and energy balance, are altered in exercising women with hypothalamic amenorrhea and (2) to assess the association between gastrointestinal hormones and behavioural indicators of subclinical disordered eating in exercising women with hypothalamic amenorrhea. This cross-sectional study...
We examined the nutritional content of and characters’ attitudes toward foods depicted in Public Broadcasting System (PBS) television programs aimed at children under age 5. Two-hundred and forty-five episodes from 10 programs were rated, totaling 136h. There was almost twice the total airtime for depictions of unhealthy (321.03min) versus healthy (184.72min) foods, and significantly higher ratings...
The purpose of this cross-sectional study was to determine the relationship between type of eating occasion based on need state segments experienced by 200 midlife women (46±6 years) and food group, nutrient, and energy intake. Women completed an Eating Occasion Questionnaire for 3 eating occasions over a 3-day period for which they maintained diet records. Cluster analysis segmented 559 eating occasions...
