All the best research I have read indicates that fat in your diet is actually good, and the real culprit for high blood pressure, heart conditions, obesity, cancer, and of course diabetes or insulin insensitivity ( precursor to adult diabetes) is sugar and high carb intake....this MEANS that breakfast cereals should be terminated....eggs and a small amount of a complex carb ( not bagels or bread which break down immediately to sugar) --or just eggs and olive oil or omelette.
The actual pathway for the sugar damage is A.G.E ( Advanced Glycation End Products).
The conceptual for this re-understanding of why fat is good, and sugar is bad is well done with this Mercola article

This anti-aging article by Mercola actually explains the Advanced Glycation End Products pathway and damage in an ideal way for most people on SB....and relates it to the food choices you make, including breakfast.
Why Avoiding Sugar is a Good Anti-Aging Strategy
In case Mercola gets on your nerves, here is the A.G.E. issue from a standard medical source
