I know next to nothing about this topic but heard in an interview with Ventura, that Hogan was the only one of that league (or how they call it) who had already signed a fat contract with a higher league and that the unionization would have put that into risk of not proceeding.
Edit: Found the interview. It was a bit different than I remembered but not much.

But also the sugar and fat part has pretty serious consequences in parts of the world like Diabetes type 2 and the displacement of traditional cooking and is linked to political issues like lobbying. This long NYT article from 2017 about Nestles manipulation of eating habits in poor comunities in Brazil shows the impact (don't know if it has gotten better, though). Even obese people can be malnutritioned and once you aquired Diabetes Type 2 it can only be remedied, not cured.
