Extreme weight loss, dizziness or fainting, nausea and stomach pain
This is a tricky question - new studies actually show that people who skip breakfast aren't at all heavier than people who don't skip it. The myth that people who regularly breakfast aren't as heavy as people who do skip it has arisen through bad scientific studies that were being conducted in the past. Newer ones, however, show that this isn't the case. For that reason, your question is invalid :)
Good, thanks for asking! How about you?
Well, if you are around people who smoke, and you are inhaling that smoke, technically. you are smoking.
