Motivation is a complex neurobiological process that initiates, directs, and maintains goal-oriented behavior. Although distinct components of motivated behavior are difficult to investigate, appetitive and consummatory phases of motivation are experimentally separable. Different neurotransmitter systems, particularly the mesolimbic dopaminergic system, have been associated with food motivation. Over the last two decades, however, research focusing on the role of opioid signaling has been particularly growing in this area...

Many eating behaviors form in childhood, and some unhealthy behaviors may persist into adulthood and have potential impacts on people's health. This study evaluated the effectiveness of behavioral intervention in reducing consumption of Western fast food, sweetened beverages, fried food in preschool children, and changing parents' rewarding behaviors that encourage the consumption of the unhealthy foods. The research was a cluster randomized trial of seven kindergartens, involving 1138 children aged 3-6 years and their parents in Beijing, China...

Compulsive eating behavior is a transdiagnostic construct that is characteristic of medical and psychiatric conditions such as forms of obesity and eating disorders. While feeding research is moving towards a better understanding of the proposed addictive properties of food, the components and the mechanisms contributing to compulsive eating are not yet clearly defined or understood. Current understanding highlights three elements of compulsive behavior as it applies to pathological overeating: 1) habitual overeating; 2) overeating to relieve a negative emotional state; and 3) overeating despite aversive consequences...

The natural like and dislike of foods based on taste is one of the most easily observed behaviors in animals. Animals eat palatable foods and reject aversive foods, which makes measurement of taste perception possible using various behavioral techniques. Three different methods to accurately measure taste behavior are described here. First, two-bottle preference tests evaluate whether a taste compound (tastant) is preferred over water. Second, lickometer tests quantify the like and dislike for multiple concentrations of the same tastant or multiple tastants at the same time...

BACKGROUND: The treatment of methamphetamine dependence is a continuing global health problem. Agonist type pharmacotherapies have been used successfully to treat opioid and nicotine dependence and are being studied for the treatment of methamphetamine dependence. One potential candidate is lisdexamfetamine, a pro-drug for dexamphetamine, which has a longer lasting therapeutic action with a lowered abuse potential. The purpose of this study is to determine the safety of lisdexamfetamine in this population at doses higher than those currently approved for attention deficit hyperactivity disorder or binge eating disorder...

BACKGROUND/OBJECTIVES: Controlling food portion sizes can help reduce energy intake, but the effect of different portion-control methods on weight management is not known. In a one-year randomized trial, we tested whether the efficacy of a behavioral weight-loss program was improved by incorporating either of two portion-control strategies instead of standard advice about eating less. SUBJECTS/METHODS: The Portion-Control Strategies Trial included 186 women with obesity (81%) or overweight (19%)...

Ryan S Mattfeld, Eric R Muth, Adam Hoover
The universal eating monitor (UEM) is a table-embedded scale used to measure grams consumed over time while a person eats. It has been used in laboratory settings to test the effects of anorectic drugs and behavior manipulations such as slowing eating, and to study relationships between demographics and body weight. However, its use requires restricted conditions on the foods consumed and behaviors allowed during eating in order to simplify analysis of the scale data. Individual bites can only be measured when the only interaction with the scale is to carefully remove a single bite of food, consume it fully, and wait a minimum amount of time before the next bite...

The purpose of this study was to identify common barriers and facilitators to healthy nutrition and exercise behaviors in the workplace and examine their relationships to those actual daily health behaviors. We utilized a concurrent embedded mixed methods approach to collect data from 93 participants over the span of four days. Participants reported 2.80 nutrition and 3.28 exercise barriers on average over the 4 days, while reporting 2.93 nutrition and 1.98 exercise facilitators in the same timeframe. Results indicated that workload and temptations around the office prevented nutritious eating; exercise behaviors were frequently hindered by workload...

We conducted a preliminary investigation on the resistance to, and persistence of, social influence regarding the appropriate amount to eat, defined in terms of eating an amount similar to that eaten by a confederate. Participants ate pizza both alone and in the presence of remote confederates presenting either a high or low eating norm. In the portion of the experiment examining resistance to social influence, participants given an initial opportunity to form a personal eating norm by eating alone for one session in the absence of social influence were no more resistant to low eating norms than were those who had no such opportunity; however, those who ate alone for two or three prior sessions did show resistance...

OBJECTIVE: Although cognitive-behavioral therapy (CBT) represents the first-line evidence-based psychotherapy for bulimia nervosa (BN), most individuals seeking treatment do not have access to this specialized intervention. We compared an Internet-based manualized version of CBT group therapy for BN conducted via a therapeutic chat group (CBT4BN) to the same treatment conducted via a traditional face-to-face group therapy (CBTF2F). METHOD: In a two-site, randomized, controlled noninferiority trial, we tested the hypothesis that CBT4BN would not be inferior to CBTF2F...
