Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The investigational product is a standardized extract obtained from the juice of Moro red oranges (Citrus sinensis). Citrus sinensis is a TGA approved therapeutic ingredient in complementary medicines.

The trial product will be in capsule form, containing 400 mg of Morosil extract to be taken once per day with 200 mL water at breakfast.

All participants will receive the same standard advice regarding physical activity. Specifically, participants will be asked to undertake 30 minutes of walking 3 times per week and record all physical activity in their diaries.

In terms of dietary advice, participants will be asked to follow a kilojoule controlled diet. The amount of kilojoules to be consumed daily by each participant will be calculated using the basal metabolic rate score from their DEXA scan.

Adherence will be monitored by trial product container return at the end of the study allowing for capsule count.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The potential participants are screened by the investigator for inclusion in the study. The eligible participants are enrolled by investigator and provided with a "Numbered Container" that is identical to all other containers and contains the same information on the label, except for the number. The investigator is blinded to the product randomized with the
numbered containers labelled prior to delivery to investigational site. Product allocated as participants are enrolled in sequential order

Summary
Brief summary
This is a single-site, double-blind, randomised, clinical trial for 6 months treatment duration and utilising active and placebo arms with baseline data collection.

150 overweight male and female participants aged between 20 and 65 years will be recruited from databases and public media outlets. Following preliminary screening via telephone, potential participants will attend the clinic for an information session and will be required to provide their consent for inclusion in the trial. Consenting participants will undergo a health assessment including lifestyle, current medications and medical history; this data will be used for the comprehensive screening and to provide contextual data for the study.

Once enrolled in the trial, participants will be randomly allocated to either the placebo comparator group (n=75) or the active intervention group (n=75 per group). Dietary intake and body measurements (weight, height, hip circumference, waist circumference, blood pressure and heart rate) will be assessed at enrolment. Within the week pre-treatment, participant’s blood will be collected for analysis of pre-treatment blood markers. Participants will also be required to have a DXA scan.

All participants will receive the same standard advice regarding physical activity. Specifically, participants will be asked to undertake 30 minutes of walking 3 times per week and record all physical activity in their diaries.

In terms of dietary advice, participants will be asked to follow a kilojoule controlled diet. The amount of kilojoules to be consumed daily by each participant will be calculated using the basal metabolic rate score from their DEXA scan. Participants will be asked to record their daily food intake in a kilojoule counter app and submit a 24hr food recall every two months during the study. Guidance in the form of example meal plans will be provided.

Participants will be asked to take the allocated product according to the dose prescribed. In addition, participants will be asked to attend the study site at months 1, 2, 3, 4 and 5 for a body measures, dietary intake and tolerance assessment.

At the completion of the study (month 6), an assessment identical to that undertaken at baseline will be carried out.

Participants will be monitored for compliance with the protocol by a combination of telephone and email communications in addition to during each scheduled site visit.
