Whatever-his-name ( Wong? )and his "insulin hypothesis" for his "it's-not-your-fault-you're-fat" du-jour pseudo self-help book had his hypothesis falsified by his own study.

Participants lost the predicted amout of weight based on calculated caloric deficit regardless or if the diet was high or low carbs.

His hypothesis predicted high carbs would result in little or no weight loss through the magic of insulin somehow keeping your body running its basic functions, without taping significantly into fat stores despite the same caloric deficit as someone eating low carb.

So of course he simply doubled-down and keeps asserting his falsified hypothesis as truth.

Meanwhile, anyone who hasen't had their brain damaged by Fatlogic understands if the insulin of fat people is constantly elevated, it's because they eat too much so their body pretty much always has immediately avaliable exess energy to use and store ( so the pancreas must secrete insulin, otherwise the kidneys have to eliminate the excess, and kidneys get damaged if they do that too often ).

And by some "miracle" that just so happened to get confirmed again by Wong's own study. Which he promptly ignored.
