Having previously established the positive effects of protein restriction, and having narrowed it down to BCAA restriction, this experiment sought to test which of the 3 BCAAs is mediating the effect. It turned out to be mostly isoleucine, with valine playing a smaller role. FGF21 was shown to be part of what mediated the effects of isoleucine restriction.
The article reviews the literature about the Randle cycle and mitochondrial inertia, and develops a model to explain how lipids and BCAAs play together to promote insulin resistance. A literature review shows that BCAAs are associated with insulin resistance and diabetes more than any other metabolite studied. Yet the negative effects of BCAAs only seem to show up in "high-fat" diets. The authors therefore believe that BCAAs can "clog up" the TCA cycle similarly to lipids, possibly competing for similar pathways. This can then lead to glucose intolerance.
