Hi Candyapple:
I read most of the posts and I don't think the question you asked was answered. YES, you can harm yourself if you just skip breakfast. Your pancreas will start shooting out insulin and you may risk leaving ketosis.
BREAKFAST OPTIONS:
I alternate between eggs and ground flaxseed cereal. You can buy ground flaxseed at most health food stores. The ONLY caution I have about the flaxseed is try a few tablespoons first with something like Carb Countdown milk and don't let the cereal sit around - will get um....gooey, mooshy, that sort of thing. I always eat small amounts at a time so it doesn't get weird - tastes great too!

OLD FASHIONED or ORGANIC PEANUT BUTTER will have NO hydrogenated oils or sugar. Just Peanuts and Oil will be on the ingredient list.

I haven't tried any but I've seen low carb breakfast cereals by Atkins and other companies at the store recently. I won't pay the outrageous money for them (ground flaxseed should only run you about $2.00 or $3.00 a lb).
HTH
