Eat Before Exercise?
I have heard it way too often lately…."My trainer (or someone else) told me not to eat before I exercise in the morning because I will burn more fat if I exercise on an empty stomach." This is simply not true! In fact, the opposite is true. You should eat before you work out to lose weight.
When you wake up from overnight, your glycogen stores (carb stores) are pretty low. It seems logical that since your glycogen is low that you should then use fat for energy if you go and work out. If only it were that easy we would not have the epidemic of obesity that we have! Instead of your body using stored fat to fuel your workout, your body decides to use muscle instead of fat. It wants to hang on to fat, just like you like to hang on to your savings account. Your body treats your fat stores like savings and does not like to have to use them.
In addition, whenever you put your body into significant low energy, it thinks it is starving and that just teaches the body to go into survival mode and hang on to fat. Not only will you store fat, but you also won’t get a good workout. If you have ever hit the wall or felt really low on energy during a workout, it is very likely due to improper fueling before you worked out.
If you are exercising first thing in the morning, I don’t expect you to eat a large amount. Just a small pre-workout snack is enough to tell the body that it has some fuel coming in. As long as the body knows that you are giving it some fuel to work with, it will respond with burning small amounts of body fat. However, it is when the deficit is large (no food after overnight fast) that it will conserve fat storage. Even eating 100-200 calories will do the trick.
If you are not exercising in the morning, but rather at lunchtime or after work, have a small snack before your workout if it has been more than 3 hours since your last meal or snack. Again, a 100-200 calorie snack should be plenty to get you through that workout. Follow the workout with your next meal within an hour or with a snack if it will be longer than that until the next meal.
You will actually lose more body fat and perform better if you eat before working out. If you are still skeptical, give it a try for a few weeks and let me know how it goes!

This sounds like very good advice and I will try it in the future. Too bad I didn't know this sooner!
Thanks

I couldn't agree more. Exercise without adequate nutrition is a good way to get low blood sugar. When I was a kid, i used to force myself to exercise through the hunger and I developed hypoglycemia. For me, a protein shake is perfect before exercise and I keep a beverage on hand during exercise.

I had another question about green tea. Is there a certain kind you have to get to get the nutrients from it? Is the kind in the grocery store ok or should you get if from a tea specialty shop? Is it ok to use a tea bag? How much of it do you have to drink a day for it to be good for you?
Thanks for your help!
