Proteins drives insulin often more than carbs, which is why diabetics individuals must often bolus more for proteins rich foods than carbohydrates. Pennington model explains a defect where lipogenesis is faster than lipolysis and because of this an adaptation is required to prevent a total (maybe deadly) lack of energy for the invidial where adopicites becomes bigger and hence the instruction for the body becomes to store fat (regardless of insulin levels) Your model just claim that a transporter hormone arbitrarily makes everyone's body store fat for everyone just by being released, which of course is not even remotely true.
