I've been reading the book "Why we get fat and what to do about it" by Gary Taubes. I'm only now starting to read and slightly understand how energy systems work and how nutrients are stored.

Can somebody please explain what happens when a person does not eat breakfast and lunch and then subsequently eats a huge dinner.

Let's assume that obesity is a problem for this made up person. What, within the hormonal system, contributes to that fat accumulation? Obviously there is a spike in insulin and thus a storage of fat from the excess insulin, leading to more and future insulin resistance.

How does the long fast affect things? That's my main question.
