Data collection occurred between June and July 2024 using a piloted questionnaire administered via Qualtrics market research services.

The survey included open-ended questions, free-listing tasks, UPF functional knowledge measures (e.g., identification of UPFs among 20 images of products; Food Processing Knowledge (FoodProK) Score), and triadic sorting techniques (used to identify attributes associated with UPFs). Multivariable linear regression models were fitted to examine associations between the number of items correctly identified as UPFs, and FoodProK scores, with socio-demographic characteristics.

Hormonal changes during menopause exacerbate loss of lean mass, visceral fat gain, and risk of cardiometabolic disease. Resistance and high-intensity interval training (HIIT) are effective countermeasures, with adequate protein and fibre intake essential to support favourable adaptations. However, many women fall short of these protein and fibre dietary recommendations, particularly at breakfast. Defatted almond protein powder (APP), a by-product of almond oil production, is rich in protein and fibre and may enhance exercise-induced adaptations, though its effects remain untested.</p><p><strong>Methods: </strong>This protocol outlines a 12-week study comprising a 10-week supervised resistance and HIIT intervention, with baseline and post-intervention assessments conducted over one-week periods immediately before and after the intervention. The randomised, double-blind, placebo-controlled trial will investigate the effects of defatted APP supplementation in postmenopausal women. We aim to recruit 48 participants who will be randomly allocated to receive either APP or an energy-matched placebo (maltodextrin). Primary outcomes include changes in total and regional lean mass which will be assessed using dual-energy X-ray absorptiometry (DXA). Secondary outcomes include strength, assessed via 3-repetition maximum (3-RM) chest press and leg press, and maximal handgrip strength; cardiovascular fitness (VO₂peak); total body fat (absolute and %), blood lipids; blood glucose; insulin response; appetite; supplement acceptability; and dietary intake. Data will be analysed using linear regression and mixed-effects models under intention-to-treat and per-protocol frameworks.</p><p><strong>Discussion: </strong>This study will be the first to examine the effects of daily supplementation with APP on musculoskeletal and metabolic outcomes in postmenopausal women undergoing structured and supervised exercise training. Findings of this study may assist in developing applications for high protein/fibre by-product from the nut/seed oil industry and determine if supplementation with this almond derived product is an effective nutritional strategy to support training adaptations to strength and HIIT training in ageing women.</p><p><strong>Trial registration: </strong>ANZCTR: ACTRN12625000133437 (Date Registered: 06 February 2025).
