I am one of those people who never get hungry. I don't fast, but don't eat breakfast, skip lunches once in a while. Usually have a large dinner. I am not skinny but slightly overweight, according to BMI (25.1). But when I purposefully eat as much as possible on vacations (trying out all of the famous places, you know), then for next week or two I get hungry all the time. It takes a lot of time before I could get back to my normal eating schedule. I really don't care one way or other but my busy schedule just get in the way of regular lunches. Also I have been going to same doctor for last decade and he says my health is as great as of someone 15 years younger than me.
