Effects of Whole Grain Intake, Compared with Refined Grain, on Appetite and Energy Intake: A Systematic Review and Meta-Analysis. Lisa M Sanders, Yong Zhu, Meredith L Wilcox, Katie Koecher, Kevin C Maki. Advances in Nutrition, Published: 02 February 2021, nmaa178.
Conclusion: These results support the view that consumption of WG [whole grain] foods, compared with RG [refined grain] foods, significantly impacts subjective appetite, and might partly explain the inverse associations between WG food intake and risk of overweight, obesity, and weight gain over time.

Interim analyses and the final data were shared with the sponsor prior to publication, but the final decision for all aspects of study conduct and manuscript content is that of the authors alone.
Comment: General Mills paid for the study, had input into the study design, and reviewed the data and analysis before publication. Two of the authors are employed by General Mills and the others work for a company that gets funding from General Mills. This is a study designed to help General Mills market products containing whole grains.
Marketing of whole grains is tricky. The only label that counts is 100% whole grains. Anything other than that is marketing hype.
