Some times it takes a while to get your first hunger. If you go a whole day and you are still not hungry, eat a little and try to wait for the next hunger.
Do not go more than 36 hours for your first hunger. After your first hunger your approximate hunger will come one to three times a day. You will love the energy you feel and delighted feeling you get while waiting for your next meal.
Hunger is a little burning sensation inside your stomach. If you can not eat at the time of hunger because of obligations like work or social events, hunger will return in about forty-five minutes. You can skip hunger once in a while but do not make it habit.
