Effects of a Soya-Based Fibre Beverage on Weight and Health in Overweight Adults (SBB-WEIGHTLOSS)
21 de mayo de 2026 actualizado por: Wan Rosli Wan Ishak, Universiti Sains Malaysia
Research on the Effect of Soya-Based Dietary Fibre Beverages (SBB) in Improving Anthropometric Parameters and Biomarker Profiles Among Overweight Students and Staff in Health Campus, Universiti Sains Malaysia, Kelantan
The goal of this intervention study is to evaluate the effect of soya-based dietary fiber beverage (SBB) in overweight adults. The main question it aims to answer is:
Does the SBB effective in improving the weight and metabolic parameters among overweight adults?
Overweight participants will be randomly assigned to intervention or control group for a defined intervention period. The intervention involved the consumption of the SBB beverage powder while allowing participants to maintain their usual meal portions. while the control group will be asked to continue their usual breakfast, lunch, and dinner meals during the study period. Clinical and biochemical parameters will be assessed at baseline and after the intervention period to evaluate potential metabolic changes. Anthropometric and body composition will be recorded. Assessments will include questionnaires related to food frequency (FFQ), food diary, physical activity (IPAQ), satiety and appetite, and defecation behavior.

Descripción detallada
Dietary fiber plays a crucial role in weight management by enhancing satiety, reducing caloric intake, and modulating gut microbiota.
Among various fiber sources, soya- based dietary fiber (SBB) is of particular interest due to its combined benefits of soluble and insoluble fiber, plant-based proteins, and bioactive compounds.
Studies have shown that soya proteins and isoflavones contribute to lipid metabolism, insulin sensitivity, and overall weight reduction.
However, there is limited research on the direct impact of soya-based dietary fiber beverages (SBB) on weight loss and metabolic health outcomes.
In this study, the investigators have already developed soya-based dietary fiber beverage (SBB) formulated with soymilk powder, apple mixture powder, and botanical powder.
While the formulation has been completed, its efficacy in improving anthropometric parameters and metabolic profiles among overweight adults remains untested.
Individuals who agree to participate in this study will be divided into two groups: the Control Group and the Intervention Group.
The intervention involves consume two servings of the beverage at least 30 min before each breakfast and teatime every day for 12 weeks, while the control group will be asked to continue their usual breakfast, lunch, and dinner meals during the study period.
Regular consumption of the SBB beverage over three months may lead to significant improvements in metabolic health, including a reduction in body weight, improved body composition, and enhanced satiety response.
Additionally, participants are expected to show positive changes in dietary intake patterns, physical activity levels, and quality of life.
Biomarker analysis will further assess the impact of the intervention on metabolic and inflammatory parameters.

Experimental: Soya-based dietary fibre beverage
The SBB beverage was in powdered form (1 sachet contain 53g of powder), and participants were instructed to prepare the liquid shake by mixing the 1 sachet of the powder with 250 mL of cold water in a shaker that had been provided.
They were asked to consume two servings of the beverage at least 30 min before each breakfast and teatime every day for 12 weeks.
The intervention group was given a sufficiently SBB sachet with a label indicating the ingredients and the preparation method.
The breakfast, lunch, and dinner meals were recommended as normal meals (the meals that they habitually eat).
The intervention involved the consumption of the SBB beverage powder while allowing participants to maintain their usual meal portions.
There was no strict portion control, and participants could continue their habitual eating patterns.
The focus was on incorporating the SBB beverage as part of their daily diet without restricting overall food intake.

Change in appetite
Periodo de tiempo: Baseline, week 4 and week 12

Subjective appetite sensations were assessed using an eleven-point numerical rating scale (NRS), with anchors at 0 ("not at all") and 10 ("very much"), to evaluate hunger, fullness, desire to eat, thirst, and prospective food consumption.
Participants completed the questionnaire before and after breakfast, lunch, and dinner at each study time point (pre, week 4, and post).
For analysis and comparability with conventional visual analogue scale (VAS) methods, NRS scores were linearly transformed to a 0-100 scale by multiplying each value by 10.
