If you skip breakfast won't your first meal that follows be breakfast
If you want to lose weight make sure you take in less calories than you need, let your body handle the insulin. Unless you're a bodybuilder then by all means follow whatever incomplete science you can get your hands on. If you have stuff to do in the morning that requires energy, eat. Unless you're a diabetic (or eating the kind of food that may make you one) I would not worry about insulin spikes. One way to limit the effect is by not eating giant meals, there can't possibly be a large spike if you eat throughout the day.
