Using The Bite Counter To Overcome The Effect Of Plate Size On Food Intake, Phillip Jasper
Using The Bite Counter To Overcome The Effect Of Plate Size On Food Intake, Phillip Jasper
All Theses
According to a recent National Health and Nutrition Examination Survey, overweight and obesity have reached epidemic levels in the United States (Flegal et at., 2010, NHANES, 2010) There are many treatments for overweight and obesity, the most popular being behavioral interventions (Berkel et al., 2005). Self-monitoring is one of the most important factors of successful behavioral interventions (Baker & Kirschenbaum, 1993). The Bite Counter is a newly developed tool for weight loss that aids in the self-monitoring process (Dong et al., 2011). The purpose of the current study was to determine if bite count feedback and an instruction on the …
Automatically Measuring Individual Consumption Events During Natural Eating Using A Table Embedded Scale, Ryan Mattfeld
Automatically Measuring Individual Consumption Events During Natural Eating Using A Table Embedded Scale, Ryan Mattfeld
All Theses
This thesis is motivated to improve the tools available for tracking energy intake. The goal of this work is to develop a table-embedded scale capable of measuring the weight of individual consumption events during unrestricted eating. The method was tested on a data set gathered from 276 subjects eating 518 courses consisting of 22,383 marked individual consumption events in a cafeteria environment. Approximately 30% of the consumption events can be detected and weighed. The remaining 70% of the events occur without participants interacting with the scale or when noisy interactions with the scale prevent weight measurement. The relationship between bite …
Accuracy Of A Bite-Count Based Calorie Estimate Compared To Human Estimates With And Without Calorie Information Available, James Salley
Accuracy Of A Bite-Count Based Calorie Estimate Compared To Human Estimates With And Without Calorie Information Available, James Salley
All Theses
Obesity is an increasing health problem in the US, associated with such dangerous health risks as heart disease and diabetes. Self-monitoring in the form of calorie counting is a critical aspect of successful weight loss. However, calorie estimations are subject to several perceptual and cognitive biases, and there are limited tools available to assist these estimations. The present study seeks to assess the accuracy of participants' estimations of the calorie content of meals in the presence or absence of calorie information, and to compare their accuracy with calorie estimations based on bite count. Data were analyzed for 87 participants from …

Sources Of Variance In Bite Count, Jenna Scisco
All Dissertations
The obesity epidemic affects millions of individuals worldwide. New tools that simplify efforts to self-monitor energy intake may enable successful weight loss and weight maintenance. The purpose of this study was to examine predictors of the number of bites recorded by the bite counter device during daily meals in natural, real world settings. Participants (N = 83) used bite counters to record daily meals for two weeks. Participants also recorded their daily dietary intake using automated, computer-based 24-hour recalls. Predictors of bite count were explored at the meal-level and individual-level using multilevel linear modeling. A positive relationship between kilocalories and …
The Relationship Between Energy Balance Understanding And Measures Of Wellness, Stephanie Fishel-Brown
The Relationship Between Energy Balance Understanding And Measures Of Wellness, Stephanie Fishel-Brown
All Dissertations
Much emphasis on the fight against obesity is placed on education and food labeling, yet very little research has been performed to measure how much people know about energy balance and the relationship of this knowledge to measures of wellness. The primary objective of this study was to determine if college students' (N = 262) performance on an energy balance questionnaire is associated with measures of wellness. Performance on the questionnaire as a whole was not significantly correlated (p > .05) with body mass index (BMI; rs = .04), percent body fat (rs = .05), waist to hip ratio …
The Bite Detector: A Device For The Behavioral Treatment Of Overweight And Obesity, Jenna Scisco
The Bite Detector: A Device For The Behavioral Treatment Of Overweight And Obesity, Jenna Scisco
All Theses
Overweight and obesity are primary health concerns worldwide and particularly in the United States. Currently, the most effective treatments are behavioral interventions, and a reduction of eating rate is one behavioral method that may help individuals eat less and lose weight. Additionally, adaptive eating behaviors, such as intuitive eating, have been identified as healthy body weight predictors. The purpose of Study 1 was to examine the accuracy of the bite detector, a wrist-worn device designed to detect bites of food. Participants (N = 21) ate a meal in the laboratory, and the sensitivity and positive predictive value (PPV) of the …
