Kudzu reduce apetite for beer

From Al:

Kudzu extract reduce apetite for beer among heavy drinkers. From the New Scientist:

“In the study, people who were given kudzu extract for seven days drank about one beer less in a monitored 1.5-hour drinking session than people who took the placebo, say researchers at McLean Hospital, Harvard Medical School and New England Research Institutes in Massachusetts, US. Those treated also drank more slowly.”

Although this would be a perfect adjunct, it appears that breweries would be shooting their business model in the foot.
