Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study intervention is the use of a locally designed mobile application called Nutritionist Buddy (nBuddy) facilitating behavioural change for weight loss in participants with Non-Alcoholic Fatty Liver Disease. The intervention is over a period of 6 months. This group will be guided through the use of the application through a 1 hour individual face-to-face session with the research dietitian at their first study visit. The application is provided free for these patients and they will be required to log their food intake and exercise daily. The nBuddy app will provide the participants with real-time decision-support response if the food selected is the not the best choice for him or her. They will be required to input their weekly weight using the digital weighing machine issued to them. Participants will be guided to achieve their targeted goals using in-built evidenced based behaviour modification tool. With the remote coaching through the dashboard, dietitian can view participants' diet and activities history. The chat function allows dietitian to communicate with participants daily for the first month and weekly for the subsequent months, or as and when required. Within the programme, participants will be provided with educational videos on strategies for weight loss and behavioural modifications.
A buddy support system can also be set up by participant's invitation to the application. Loved ones or friends whom the participant wishes to be accountable to, can access his or her diet and exercise history to help monitor and encourage him or her to stay on track.

Two optional workshops will be lined up for participants to join. One will be conducted on behavioural strategies for weight loss or a supermarket tour, and the other will be on the topic of sustaining weight loss.

The automation engine of the application will be able to:
- evaluate suitability of foods or meal plans in real-time and generate healthier alternatives automatically and immediately via an algorithm
- provide reports on calorie intake, calories burnt and weight in graphical formats to participants on a regular basis
- provide evidenced-based daily tips to users
- Send scripted reminders or prompts at certain time of the day, based on user's level of preference
- Implement behavioural modification strategies automatically in order to achieve and sustain good outcomes.

Dietitian dashboard will complement the application with:
- Timely escalation of question and answer
- Tracking and monitoring of results and outcomes of participants
- View participants' information such as their food choices, diet plan, exercise level
- Support and individualised feedback to users via the application
- Weekly educational videos to participants via the application

Behaviour
Comparator / control treatment
As per our current standard care, participants in control arm will be counselled individually on diet and exercise advice by a nurse practitioner during their clinic visit. The session takes approximately 30 to 40 minutes and is once off. Healthy food plate , physical activity and the importance of weight loss are key areas of focus during the counselling. They will be provided with a weighing machine for the purpose of this study.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation of screened participants to control or experimental group will be done via sealed opaque envelopes, which will be prepared by a third party not involved in the study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Stratified randomisation will be performed according to gender, BMI (< 27.5 kg/m2) or >/= 27.5 kg/m2), and age (< 40 year old or >/= 40 year old), effected by sealed envelopes, which has equal number of "intervention" and "control".
Masking / blinding
Open (masking not used)

Efficacy
Statistical methods / analysis
Postulating that there will be a mean difference in weight loss of 2.1 kg between control and intervention groups at 6-month follow-up, with 90% power at 5% significance level, and allowing for a 10% dropout rate, it is estimated that a sample size of 100 (50 per group) would be needed.
All analyses will be performed using SPSS for Windows version 21.0 (SPSS Inc, Chicago, IL, USA). Results will be expressed as mean and standard deviation for normally distributed variables and median and interquartile range for variables that did not satisfy normality criteria. Categorical data will be expressed as frequencies and percentages. To compare baseline characteristics between the control and intervention groups, for continuous variables, the appropriate parametric (independent samples t-test) and nonparametric tests (Mann-Whitney U test) will be utilized. For categorical variables, the chi-square test will be used. Between-group differences in the outcomes (weight change at 3 and 6 months) will be investigated using the analysis of covariance (ANCOVA) adjusted for baseline measurements.
