Plain English summary of protocol
Background and study aims?
Worldwide, more and more people are putting on weight, and there is an urgent need to try and understand what leads to over-consumption so we can help provide better health advice and promote the development of new products that can help people control their weight. One intriguing finding is that when people drink a drink which has a high energy content, they dont feel full and eat less afterwards. In contrast, if they have the same energy as a bowl of soup, they are able to adjust the amount they eat later quite accurately. The aim of this study is to try and find out why this is.
Who can participate?
As this study is not aiming to help specific patient groups, potential participants are normal members of the public who are healthy. As the study does require people to eat foods and drinks, you should not take part if you are diabetic, are taking prescription medications, smoke more than 5 cigarettes a day or have a diagnosed eating problem.
What does the study involve?
If you took part, you would come to our test centre on 7 different days. Day 1 would be a screening and familiarization day, and the subsequent 6 days would be the test sessions. On each of these days you would be required to eat nothing and to drink only water from 11pm on the previous night, and would first come for a simple breakfast between 8am and 10am. You would then come back 3 hours later and would be asked to consume a test drink (in the form of a fruit-juice/yoghurt drink) and then 30 minutes later would be served a lunch of pasta followed by ice-cream.
What are the possible benefits and risks of participating?
As the study involves eating foods and drinks made from regular ingredients, the only risks are to people who suffer from diabetes to who have an allergy to any of the ingredients. We will screen all volunteers and if you have diabetes or food allergies you would not be allowed to participate.
Where is the study run from?
University of Sussex.
When does the study taking place?
The study took place between March 2010 and August 2010.
Who is funding the project?
The project is funded by the UK Biotechnology and Biological Sciences Research Council (BBSRC).

Study acronym | SATED |
Study objectives | Disguised energy consumed in a novel drink will be more efficient in generating satiety when the drink has sensory characteristics that generate satiety relevant expectations. [Satiety Augmentation Through Expectation Delivery (SATED)] |
Ethics approval(s) | University of Sussex Research Governance Committee on 22 January 2010 Ref: MY0110appro |
Health condition(s) or problem(s) studied | Treatment of obesity and improved general nutrition. |
Intervention | 1. The six interventions are novel drinks formulated especially for the study, (low calorie, 78kcal, high calorie 279kcal) 2. All low energy (LE) drinks comprised of a combination of low-fat fromage frais and fruit juice with added flavourings and colours (78kcal) 3. The additional 201kcal in the high energy (HE) versions was achieved by adding maltodextrin (Cargill: 35g) and whey protein isolate (Myprotein, UK: 25g) 4. These drinks constituted the two low sensory versions 5. Sensory quality was adjusted by addition of a non-nutritive thickening agent (tara gum) and satiety-relevant flavours (vanilla and caramel) at two levels to generate medium and high sensory versions of both LE and HE drinks |
Intervention type | Other |
Primary outcome measure | 1. Intake (kcal) at a test lunch consumed 30 minutes after consumption of each test drink 2. The rated experience of appetite before, during and after consumption of each test drink and test meal measured using Visual Analogue Scales 3. Measures will be for hunger and fullness |
Secondary outcome measures | 1. Evaluations using Visual Analogue Scales of the perceived sensory characteristics of each drink (pleasant, filling, sweet, creamy) 2. Specific awareness of drink energy content obtained through a structured debriefing after the final test session |
