Industry-funded study of the week: soup prevents obesity?

When I saw the title of this study, I had two questions:

• Why would anyone do a study like this? (OK, in short-term studies, consuming water or soup before meals reduces immediate calorie consumption, but in the long term?)
• Who paid for it?  (Getting the answer to this one took some digging).

The study: Association between soup consumption and obesity: A systematic review with meta-analysis. M.Kuroda and K. Ninomiya. Physiology & Behavior,  Volume 225, 15 October 2020, 113103.

Conclusion: “soup consumption is significantly related to lower odds ratio of obesity…suggesting that soup consumption was inversely correlated with a risk of obesity.”
