Plain English summary of protocol

Background and study aims
Hedonic hyperphagia (overeating for pleasure) is a major cause of obesity. Specific foods such as snack food may cause someone to eat even when they are full. This study looks at how snack foods induce food intake using Magnetic Resonance Imaging (MRI) scans of the brain.

Who can participate?
Men aged between 25-50 years with a body mass index (BMI) of no more than 27kg/m2

What does the study involve?
All participants attend two sessions of brain MRI scans of about 40 minutes in total to see how different foods can affect the brain. These studies are completed within one week. The participants are asked to not eat for at least two hours before the experiment. Participants are scanned after viewing images of potato chips and zucchini. There is then a break of 5 minutes where the participants leave the scanner and are asked to eat either potato chips or sliced zucchini for 2 minutes, followed by another scan.

What are the possible benefits and risks of participating?
The benefit will be to contribute to the research of how diet can influence the brain. This study does not involve any major risks.

Where is the study run from?
Friedrich-Alexander-Universität Erlangen-Nürnberg (Germany)

When is the study starting and how long is it expected to run for?
December 2015 to August 2017

Who is funding the study?
Friedrich-Alexander-Universität Erlangen-Nürnberg (Germany)

Who is the main contact?
Prof. Dr. Andreas Hess

Scientific titleHigh vs low caloric food modulation of human resting-state functional connectivity in healthy individuals
Study objectivesResting state networks (RSNs) can individually adapt to experience after short time exposures to a stimulus, and these RSNs are a good indicator for addictive behaviors. The current study hypothesizes that visualization and ingestion of different food types (high-caloric: chips, and low-caloric: zucchini) will elicit distinct changes in the RSNs of healthy individuals.

Health condition(s) or problem(s) studiedNutrition
InterventionEvery subject will undergo two different fMRI sessions of ~40 minutes in total. The interval between the two sessions was 3 days. Participants will arrive to the fMRI unit previously knowing what food they will be presented each day.
The subjects will be asked not to eat food for at least two hours before the experiment.
In each session resting state will be measured twice. Each fMRI session will start by acquiring the individual anatomical imaging, followed by the first resting state RS scan, BOLD visual stimulation (presentation of different images of potato chips and zucchini) image presentation: total 196 vol. (time points) = 28 x 7 , 1 block of images contain 7 images, 1 image = 1 vol. = 3 sec). There will then be a pause of 5 minutes, where the participants will exit the scanner and be asked to consume day 1= salted potato chips 528kcal/100g 33% fats 49% carbohydrates, day 3= sliced zucchini 17kcal/100g 3% fats 3.5% carbohydrates ad libitum for 2 minutes, followed by the second resting state RS scan.
Intervention typeBehavioural
Primary outcome measureBrain activity measured using fMRI after the visual stimulation and consumption of the different foods
Secondary outcome measuresCorrelation of BMI with changes in brain activation measured using fMRI after the visual stimulation and consumption of the different foods
