I went to boot camp last Friday after we got back, and it was terrible. I woke up late and didn't have time to eat a good breakfast beforehand-just a granola bar in the car. Dear readers: don't be as dumb as me. I bonked hard. Usually the workout is tough. I'm sweating, sometimes a little light headed, and I'm breathing hard struggling to finish the exercises. Friday was just...wrong. Vision going black, sweating yet freezing cold, nauseous. I had to sit with my head b/t my legs for most of it b/c I was so dizzy. I'm super prone to head rushes (orthostatic hypotension: that dizziness, blurry vision that occurs sometimes if you stand up too quickly and your blood pressure falls.) I get these alllllll the time. It felt like that the entire time. Usually he is checking in with us, making sure we are ok and helps get us through the last reps or dig deeper. He looked at me and just said are you ok? Me: blank look, shaking my head. Him: dude. you look awful. go sit down.
So today's topic is Eating Before Exercise!
Before boot camp I usually eat a piece of bread with some peanut butter, or a banana with yogurt, or something like that. A bit of quick carbs with a little protein. I can't eat too much or I feel like I will throw up. I am not much of a morning person, so I have to make myself eat something. If you exercise late in the day it isn't so much of a concern.
Some people advocate working out on an empty stomach. The theory behind this is that without glucose, your body has to start using fat for fuel. A fun little process called glycolysis. This is an unusual and inefficient process-so usually it slows you down quite a bit. The argument is that if you continually exercise and your body has to go into glycolysis 1) who doesn't want to burn fat? and 2) your body becomes more efficient at it eventually won't slow you down as much. That is also a very quick and dirty explanation of how low carb diets work.
I admit that I don't know enough about this topic and haven't read much research on it. Bad dietitian, bad! Instead I thought I would ask you lovely people.
--Do you workout on an empty stomach if you work out in the morning? Do you think it makes a difference?
--Do you have a pre-workout snack? What is it?
And as a survey note to my tens of readers: do you read posts like this that are kind of wordy and a tiny bit more educational? I would like this blog to be somewhat informative, but I don't really know how much people want to actually read ; ) So weigh in and tell me!
