Background and study aims
Locust bean gum is a soluble fibre that increases food viscosity (making it thicker, for example, or less easy to pour). It takes a long time to be digested which means it has the potential to make people feel fuller and more satisfied for longer after eating a meal (increased satiety) without the need to provide more food with more calories. The effects of locust bean gum on satiety may be related to its effects (delay) on gastric emptying (the amount of time it takes for food to be taken from the stomach into the small intestine). We want to look at how locust bean gum (viscogum) added to a fishball meal might affect how much people eat of the meal, how quickly they eat it, how full they feel afterwards and how much they eat at their next meal.

Who can participate?
Adult females aged between 18-55 that are either overweight or obese, with a body mass index (BMI) of 27.0 – 31.9.kg/m2.

What does the study involve?
Participants are asked to attend two full testing days. For both days they eat a breakfast, a fixed lunch (the fishball meal) and a dinner of which they can eat as much as they like in the University of Liverpool's eating behaviour laboratory (Kissileff Laboratory). Each participant is randomly allocated to eat either a fishball meal with the viscogum added or a “control” fishball meal (which doesn’t include the viscogum) on their first visit. They then have a break from the testing for a week (referred to as a wash out period) before coming back to the laboratory to eat their second meal. Participants who ate the fishball meal with the viscogum on their first visit are given the control fishball meal on their second visit and vice versa. Each participant is also asked to attend screening and testing sessions, which includes filling in a series of questionnaires and measuring their height and weight, before coming in for the two full testing days.

What are the possible benefits and risks of participating?
There are no direct benefits to participating but knowledge gained will help to better understand what kind of foods may help people control their weight. All the foods used in the study are either commonly available or specifically developed to be eaten from a combination of commonly available foods with extensive food safety tests and are cooked in a conventional manner. Viscogum (guar gum) comes from the from the Carob plant, a natural source used in modern food processing. In the unlikely event of an emergency, The Kissileff Laboratory has dedicated first-aiders and an emergency procedure is in place should this be necessary.

Scientific titleExperimental study to investigate the acute effect of a fishball meal enriched with locust bean gum (Viscogum) on food intake and the experience of appetite
Study objectivesTo investigate the impact of a fishball meal with (experimental) or without (control) a soluble fibre (Viscogum) on food intake, feeding behaviour and experience of appetite in female volunteers with a BMI of 27-31.9 kg/m2
Ethics approval(s)Liverpool Committee of Research Ethics, 24/07/2014, ref: RETH000565
Health condition(s) or problem(s) studiedEffects of a soluble fibre type on appetite to inform about future weight interventions/obesity
InterventionThe study will involve 34 female participants attending the Kissileff Laboratory on two study day visits in which they will receive the active (viscogum guar gum) fishball meal for lunch on one day and a control (placebo) fishball meal on a separate day. Participation will include a 1-week wash out period between visits. All participants will undergo both conditions which will be randomized using a Latin Square design.
Intervention typeOther
Primary outcome measureCurrent primary outcome measures as of 25/05/2017:
Changes in energy intake (weight (grams) and calories (kcal) consumed) after intake of a lunch containing either soluble fibre or no fibre. Specifically looking at dinner and evening snack intake.

Previous primary outcome measures:
To demonstrate:
1. Reductions in eating rate at a fixed load meal including consumption of viscogum containing fishballs in comparison to control (calculated as grams consumed per minute)
2. Reductions in caloric intake at a subsequent ad libitum meal following consumption of viscogum containing fishballs in comparison to control (measuring food intake - grams/calories consumed)
3. 24 hour reduction in caloric intake in ad-libitum meals following consumption of viscogum containing fishballs in comparison to control (measuring food intake - grams/calories consumed)
Secondary outcome measuresCurrent outcome measures as of 25/05/2017:
1. Appetite (hunger, fullness, prospective intake, desire to eat) is measured using the visual analogue scale with measurements taken throughout the test day (hourly) and at pre- and post-meal as well as during the meal consumed (every 50g eaten) with a meal either containing a soluble fibre or containing no fibre.
2. Changes in meal duration of a fixed load meal including fibre containing fishballs compared to the control at the time of intake during the meal.
3. Changes in macronutrients intake and duration of a subsequent ad libitum meal following consumption of fibre containing fishballs compared to the control.

Previous secondary outcome measures:
To investigate:
1. Changes in within meal satiation during ingestion of viscogum containing fishballs compared to control using Visual Analogue Scale (VAS) appetite measures (hunger, fullness, prospective consumption, desire to eat)
2. Changes in meal duration of a fixed load meal including viscogum containing fishballs compared to control (measuring time of intake during the meal)
3. Changes in macronutrient intake and duration of a subsequent ad libitum meal following consumption of viscogum containing fishballs compared to control
4. Subjective experience of appetite and snack palatability using Visual Analogue Scale (VAS) measures
