Although a very popular misconception amongst many of today's conventional training circles, it is not true that one's metabolism (or in this case, fat burning mechanism) will slow down appreciably within a few hours of not having eaten. If you're worried about it, though, feel free to eat a handful of nuts or berries, a piece of beef jerkey, etc., at some point during the day, and be sure to remain adequately hydrated. Remember, though, that the body also benefits from allowing the digestive system to rest, which is one reason that intermittent fasting can so greatly improve health.
Oh, and welcome
