Over the last 30 years, research into food and blood glucose response has completely changed our carbohydrate classification system.
It has been learned that it is impossible to predict the impact on blood glucose levels by certain foods, instead people are fed carbohydrate foods and the response measured.
This response is known as the Glycemic Index (GI), it is a measure of how quickly carbohydrate foods are digested and absorbed, and ranks carbohydrate foods according to their impact on blood sugar (glucose) levels: as indicted by elevated blood glucose
Foods with a high GI are absorbed quickly into the blood stream and cause a rapid rise in blood glucose levels. While foods with a low GI are broken down more slowly over time and keep blood glucose levels more stable (Remember that low is slow!).
Some carbohydrate foods will maintain your energy levels for hours, while some may cause your blood glucose to rise and fall. Different types of carbohydrate can also affect feelings of fullness in the stomach and this can influence hunger and your ability to control your body weight.
When our blood glucose levels are stable we have plenty of readily available fuel for the brain and muscles. If our blood glucose levels drop too low (hypoglycemia) we feel tired, dizzy and generally unwell. If our blood glucose levels rise too quickly a rapid drop usually follows this.
Include low glycemic index foods in meals and snacks to slow the release of glucose into the bloodstream. A low glycemic index snack a few hours before exercise will help maintain your energy levels for more effective training. After high intensity exercise (strength training) a high glycemic index snack should be consumed within 30 minutes. This will help to replace energy and start the recovery process.
Low-GI foods take longer to digest and help delay hunger pangs that little bit more and thus promote weight loss. So please choose your carbs carefully as this will lower your insulin levels and burn more fat. The secret is to swap high GI foods with low GI foods.
Low GI foods are ideal for losing weight due to the slow absorption from the stomach. Low GI foods also help to keep blood sugar levels more stable and this has an effect on reducing sweet cravings.

dont listen to the people that say dont eat
DO EAT....but something light like fruits or veggies, no steak and eggs save that for after the workout
the reason breakfast is called what it is, is because you haven't eaten in 8+ hours and your body will be craving something as you've just starved it......see it as a break from a fasting
you just want enough energy to get through your workout without feeling light headed and wanting to drop....you want the most effective use of your time while at the gym and having some food will make sure you get that

Fresh fruit and a protein shake (GNC Proformance is a good one). This will provide the low glycemic carbs you need for energy and the protein you need for an effective workout. Try to eat at least 30 minutes before exercise. Try to have another protein shake an hour after exercise. You can premix these in a plastic bottle and put them in a small cooler.

It all depends on you. I love working out in the morning, but I can't workout with anything in my stomach, so I don't eat anything before, but make sure you eat something after, a power bar or something with protein and sugar, then eat a "normal" breakfast about 1 hour or so after that. If you deside to eat before, do something light like yogurt or a protein shake.

You should eat before exercise. Don't enter exercise hungry! Take high fiber foods about 2 or 3 hours before getting exercise. Oat, bread, juice, pasta, fruit like banana or energy bar are among the good foods you can eat before exercise.

Dear Bro,
Everybody know it is good with an empty stomach. If you want then take some soft drinks like juice/ water of coconut before 3 hrs., going to gym. The soft drinks are easily digestable.

In the morning, I usually just drink water and head straight there. you burn more calories that way. If you are hungry, grab some yogurt or a granola bar :) Good luck!

overall, you should just eat something light, you don't want to workout on a full stomach, I would say a protein bar with a peice of fruit is perfect.
