Research Impact: Our objective was to devise and implement a dietary standardisation protocol for use in nutrient plus exercise intervention studies, and to report participant adherence to, and acceptability of same. The context was a nutrient x exercise intervention study undertaken by resistance-trained men. Participants’ habitual dietary intake informed the dietary standardisation protocol. Participants received a six-day meal plan that was prescribed relative to their body mass, distributed across six eating occasions daily, at three-hour intervals during waking hours. Participant adherence to the prescribed meal plan was excellent. The offered dietary standardisation was effective in minimising the variability of dietary intake among participants undertaking a nutrient plus exercise intervention, resulted in high participant adherence and was well accepted. The authors propose that the implemented dietary standardisation may be an effective approach in minimising the inter- and intra-participant variability of dietary practices within nutrient plus exercise intervention studies. The application of our approach requires expertise and understanding of participants’ dietary intake and training patterns and collaboration between registered dietitians, chefs and sports scientists.
