Important to note here is that the diet guidelines are largely used to underscore the USDA's funding for production guidelines. Carb-heavy diets are tied to grain-heavy cultivation. You might be able to think of a company or two that might be significantly interested in slowing that turn for as long as possible.

I haven't been able to find any recent documentation of those conversations, but they're understandably difficult to track. The guidelines here aren't a micro-service, and they're too tightly coupled to all the other fingers in the pot.
