NCT ID: NCT01398059 Completed - Feasibility Clinical Trials

The Metabolic Effects of Breaks in Sedentary Time

Start date: July 2011
Phase: N/A
Study type: Interventional

The purpose of this study is to determine whether acute bouts of sedentary behaviour (with or without breaks and/or structured physical activity) result in measurable changes in metabolic health in children and youth.

NCT ID: NCT01259895 Completed - Obesity Clinical Trials

Effects of Time of Sleep Restriction in Obesity

Start date: February 2009
Phase: N/A
Study type: Observational

The purpose of this study is to determine the effect of different time of sleep restriction on control of food intake and metabolism of obese and normal subjects.

NCT ID: NCT01141140 Completed - Obesity Clinical Trials

(Mis)Perceptions About Healthy Eating: Effects on Food Intake and Appetite in Men and Women

COLLATION
Start date: September 2009
Phase: N/A
Study type: Interventional

In the face of an increased prevalence of obesity and chronic diseases in Canada, much effort has been invested to educate the population about healthy eating. Although Canadians are now aware of the importance of healthier food habits, rates of obesity and chronic diseases are still increasing. In addition, even if different labelling strategies are used to identify healthier foods in the market, consumers remain confused about what healthy eating should be. Might describing foods as healthy have unintended side-effects on food intake? Previous literature has shown that perceptions about the healthiness of foods may bias estimations of caloric content of foods, leading consumers to underestimate the caloric content of "healthy" food choices. Indeed, the investigators have recently shown that perceiving a food as healthy increased intake of that food by 35% in undergraduate female students. The general objective of the proposed research is to investigate whether food perceptions influence intake and appetite sensations in normal-weight and overweight/obese restrained and unrestrained males and females. This laboratory study, in which perceived healthiness and "fatteningness" of oatmeal-raisin cookies will be manipulated during an ad libitum single-meal occasion, will increase the investigators knowledge of the effects of external cues (and other psychological and physiological factors) on the control of food intake. Because the popularity and demand for nutrition information is increasing, such information is needed to improve clinical practices aiming at promoting sustainable healthy eating habits to help individuals achieve and maintain a healthy weight.

NCT ID: NCT00436878 Completed - Eating Clinical Trials

Intake Promoting Effects of Large Portions in Children

Start date: October 2005
Phase: N/A
Study type: Interventional

The purpose of this study is to test the effects of large food portions on children's eating. Experiment 1 will test the effect of portion size on children's consumption of sweetened beverages; we hypothesize that serving large beverage portions will increase the amount of energy children consume from this food. Experiment 2 will test the effects of portion size on children's intake of fruits and vegetables (FV) affect intake whether such effects are moderated by children's FV preferences and; we hypothesize that serving large fruit and vegetable portions will produce increases in children's intake of these foods, particularly for children who like fruit and vegetables. Experiment 3 will evaluate how food energy density affects children's response to large portions; we hypothesize that large portions will have the greatest influence on children's energy consumption when foods are energy dense. Experiment 4 will begin to address perceptual mechanisms by which large portions affect children's eating.
