Use a simplified grocery list template (3 vegetables, 3 proteins including one plant-based and one fatty fish, 2 whole grains, 2 fruits, 2 spreads) to eat a balanced diet without the need for planning or recipes during busy weeks.

This method of simplifying grocery shopping is based on nutritional principles that are firmly validated by science. Incorporating fatty fish on a weekly basis to obtain omega-3s is supported by observational studies and recommendations from authorities such as ANSES, which associate these fatty acids with cognitive and cardiovascular vitality. Similarly, prioritizing high-fiber whole grains and legumes is validated by large-scale meta-analyses (notably the one by Andrew Reynolds published in The Lancet), demonstrating clear benefits for satiety and digestive comfort. In terms of behavior, observational studies in health psychology suggest that simplifying decision-making through the use of simple meal structures helps avoid decision fatigue and improves overall meal quality. Although there is no randomized controlled trial (RCT) specifically testing the efficacy of this precise '3-3-2-2-2' formula, its flexibility encourages good dietary diversity, which is essential for microbiome balance according to expert consensus. It is a pragmatic, scientifically coherent organizational strategy that is free from exaggerated promises.
