Alan Aragon once noted:

"If you’re willing to dismiss research on the grounds of funding source (a bias on its own), then you’d have to be consistent & dismiss most diet/nutrition research in existence, including any beloved reviews/studies that support your own opinions."

Because most studies have to be funded to be carried out. Also:

"Without industry funding available, the march of science would be severely limited."

You have to understand (which you obviously don't) that just because a study is funded by a sponsor it doesn't mean it's biased. You need to understand that there's a sponsor’s complete separation from design, interpretation, & publication.

And by the way, that study by Kevin D. Hall was not sponsored by NSI. It was sponsored by the Intramural Research Program of the National Institutes of Health, National Institute of Diabetes & Digestive & Kidney Diseases. No bias whatsoever.
