This year, I'll be speaking on insulin and obesity.  My talk will be titled " Insulin and Obesity: Reconciling Conflicting Evidence ".  In this talk, I'll present the evidence for and against the idea that elevated insulin contributes to the development of obesity.  One hypothesis states that elevated insulin contributes to obesity, while the other states that elevated insulin is caused by obesity and does not contribute to it.  Both sides of the debate present evidence that appears compelling, and it often seems like each side is talking past the other rather than trying to incorporate all of the evidence into a larger, more powerful model. There's a lot evidence that can be brought to bear on this question, but much of i...
