Study characteristics
Methods	Randomised controlled trial
Participants	24 Participants Inclusion and exclusion criteria: nothing noted
Interventions	2‐arm trial Intervention: twice‐weekly diet Comparator: standard energy‐restricted diet (SERD) (2050 KJ (500 calorie) reduction per day) for 6 months.
Outcomes	Weight, waist circumference (WC), fasting blood glucose, blood lipids, blood pressure and dietary intake were measured at baseline
Notes	Type of paper: abstract only Funding: no data provided Abstract did not provide detail on how many people were in each arm of the trial and no contact details were provided, therefore the few data provided in the abstract cannot be included in the meta‐analysis at this stage.
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Abstract only and method of randomisation not stated in abstract.
Allocation concealment (selection bias)	Unclear risk	Abstract only and allocation concealment not indicated.
Blinding of participants and personnel (performance bias) All outcomes	High risk	Since this trial was a dietary intervention study, it was not feasible for participants or all study personnel to be blinded to the group assignment.
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	Abstract only and blinding of outcome assessment is only indicated by quote: "... [outcomes were] measured at baseline, 3 and 6 months by a blinded investigator"
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	Abstract only and loss to follow‐up not reported in abstract.
Selective reporting (reporting bias)	Unclear risk	Abstract only.
Other bias	Unclear risk	Abstract only.
