Going to the gym really early

Most likely you will need to eat something to have energy to make the best of it. It does not have to be really heavy... Maybe a meal bar or something... something will enough energy to get you going but not so much as to cause you to get nausiated.

it's generally good to have something LIGHT to eat pre workout. For me, i usually will have a hard boiled egg with a slice of ham.

I think it depends on the person. I am borderline diabetic and have found that if I don't eat and go work out that I get ill after. It is best I think to eat something small either way. Someone once told me to eat a fruit and/or protein. It does help.

I go at 5:30 AM and do not eat beforehand. I eat when I get home.

I get up at 5:30 and go the gym and usually don't eat before hand. If I do eat I usually will grab a banana.

If I didn't eat before my gym classes, I would lose energy because I lift heavy and expend a lot of energy. I eat a protein bar and a glass of skim milk before I go and when I get back I make a protein shake with whey protein powder and fruit and milk.

i always eat a bowl of cereal and wait like a half hour to go, just so it digests a little bit first :P

I'm at the gym most mornings at 5:00 a.m. and the majority of the time I do not eat anything. On a few occassions when I did eat, it is usually a banana and/or a few almonds. For what its worth; I usually eat a high protein breakfast usually within a hour after my workouts!

If you're not hungry, you don't need to eat, though you'd probably have more energy if you ate IF you're doing something intense like cardio; if you're weight lifting, you don't necessarily have to have anything before if you eat something high in protein and enough carbs after.
I would suggest pairing a protein with a carbohydrate before working out. Perhaps a whole wheat English muffin with a tablespoon of peanut butter and even a piece of fruit.

Generally no.. If it's a week day I normally go to the gym around 6:30 7, and I will only have a cup of coffee before hand and eat breakfast at work, normally around 9, 9:30. If i'm running a race on the weekend, it's normally a little later, either 9am or 11 and I still try to avoid solid foods, I cramp if I eat before hand. If I wake up hungry I'll do a banana and half an energy bar and just tough it out until after.

I've been going to the gym at 5 a.m. when it opens, just to make sure I can get one of the elliptical machines I like using before the morning crowd comes, and I've been doing well keeping a little bag of almonds or something in the car for after I work out (another friend said she drinks a bit of chocolate milk just to provide protein after a workout). But I've been reading up on weight training, and it seems like you should wait an hour after waking up before you do any serious lifting or stretching (your spinal discs fill with fluid overnight, according to Stuart McGill in Ultimate Back Fitness and Performance).

What type of workout are you doing? Cardio or weights. If just doing cardio, an empty stomach is fine and some people actually swear by fasted cardio. If hitting the weights on the other hand, you should have a high quality meal with protein and carbs about an hour beforehand. I have egg whites and oatmeal which helps fuel a strenuous workout.

I usually wake up early enough to eat and allow my food to digest before I go to the gym.

This is a matter of personal preference. Some people feel nauseous if they don't eat, others are just fine. Many people who follow an Intermittent Fasting protocol do not eat before an early workout.

I workout at 5:30 AM and I don't eat before. It is really up to you. Either way is just fine.

I go at 4am so I don't eat before I go. I wait until I get back home before work
