Well, he's a very pretty young man.

But yeah, where's the explanation for the "obese inside" claim? I can't tell if he's just claiming "metabolic obesity" due to low carb, or what?

Looks like Drew is type-1 diabetic, so carb intolerance would be a real problem--if he insists on eating carbs. For a type I--you cannot hope to mimick a working pancreas with injected insulin. Pancreatic insulin is secreted centrally, much of it is cleared by the liver, much of the work of glucose regulation achieved before the insulin hits the general circulation, and much of the insulin has been cleared by then. Peripherally administered insulin just isn't the same. The smaller the dose of insulin you need, the closer exogenous insulin comes to acting like endogenous insulin.

By his own testimony, until he substantiates the "obese within" claim, I consider Drew a poster-boy for keto for type I diabetes.
