2.4. Dietary Intervention and Randomisation
Following metabolic testing at week 0, 60 participants were randomised with a 1:1 ratio to red (placebo) or blue (avocado) for 12 weeks. Stratified blocked randomisation by sex was employed using a web-based system under the direction of LKH, who had no contact with participants. This study was double-blinded; neither participants nor study personnel knew the randomisation scheme. Both groups were instructed to consume one scoop (~10 g) of AvX or placebo, daily, with breakfast. No other dietary instructions were provided, and participants were asked to maintain their usual daily physical activity and sleep patterns throughout the study.
