I used to always eat before I worked out. As above -- a small bowl of cereal, then a wait of about 20-30 minutes before beginning to warm up. Then I kept hearing that it was better for weight loss to workout on an empty stomach, which I couldn't fathom doing because I lose energy and feel nauseated if I'm too hungry (and I am ALWAYS hungry in the morning). I tried exercising on an empty stomach a couple of weeks while doing Slim in 6, and I was MISERABLE the whole time. I felt sick and weak, and I kept thinking: "How can anyone do this?". My brother, who is a miniature Arnold Schwarzenegger will always tell me: "You need to do cardio on an empty stomach", but I just did a search, and found a muscle/fitness website where someone asked the same question, and this was the response:
QUESTION: To promote fat-burning from my morning cardio, should I eat beforehand or work out on an empty stomach?
ANSWER: We know of no data showing that eating or not eating before exercise will have any effect on weight loss. Common sense would suggest eating something beforehand, although not so close to your training as to provoke nausea or gastrointestinal discomfort. If you don't eat and experience low energy during the subsequent exercise, you'll be unlikely to continue your exercise program. Do whatever you can to make sure the exercise "feels good." If it doesn't, you won't continue doing it.
YAY!!! :7 Now I will not torture myself any longer, and I won't feel so bad about that small bowl of cereal before my workouts. Everyone IS different, and if it works for others to exercise without eating, that's fine, but I know for a fact that it makes exercise a horrible experience for me. Go figure.
