Hideous? Bit harsh of a word to use considering that you have not offered any advice yourself

Any halfway intensive exercise on a full stomach is bad news. There isn't a problem with having a banana or a small bit of pasta or a slice of wholemeal bread to break hunger maybe 90 minutes before but certainly no heavy meals It exposes you to cramps in your torso area, it makes you liable to get dozy and limits it's flexibility big time so you either end up either not enjoying the work out, feeling or even getting sick, unable to push yourself as much as you can or a combination of all three. The body does prefer small meals eaten often as it's easier to deal with but still nothing heavy pre workout.

Also, there is are nutritional reason to take into consideration. The fuel the body takes in through complex carbohydrates take hours to break down into sugars and are ample fuel for the body while exercising; they are also a regulated supply that the gut likes to deal with. If you start a work out and the body needs an immediate kick and the quick carb supply isn't there, it will burn anything it has handy; this usually ends up as fats and protein which are needed for different reason in the body that will need to be replaced (More eating, in other words), they are harsher for the gut to digest and they are no better for fueling your work out than carbs in the end. In short, your tummy won't like you that much and your metabolism will go ape in time.

Lastly, there isn't that much risk of your blood sugars dropping to dangerous levels unless you either have starved yourself silly that day or are diabetic. Diabetics know better than most people how to look after their eating patterns and are wise to things like that.
