No. I can elaborate but generally it's the glucose that stimulates the insulin release (the pancreas has glucose receptors).
Weight gain IS NOT driven by insulin or glucose. You can put someone on euglycemic clamp literally pumping him with insulin and glucose and he won't get fat from that. He will hover start storing fat IF we give him too much glucose for his needs.
Frankly, if you were a very mad you could theoretically put yourself on insulin/protein infusion to lose fat.
Idea being that insulin will drop your blood glucose (via insulin-dependant glucose transporter translocation) forcing liver to balance that out. When liver runs out of stored glucose it will start breaking down fat.
The downside of that is that eventually muscles won't store more glucose (you'd somehow need to get rid of that) and the risk of dying is pretty high.
