Eat or not before swimming in Early Morning?

Are you asking for medical advice? :angel: I am not going to answer your question, sorry, but I do believe I have read, and it makes sense, that you do want to consume something before workout. This is not to prevent harm, but provide more energy for the workout. You are in a fasted state, so your circulating blood sugar is fairly low, especially when you could have cake for breakfast. In an ideal situation, fat can provide you with 480 calories/hour, and then the rest has to be in your liver and muscles already. If you assume a very hard workout burns 1200 calories/hour, a long hard workout might be a problem if you don't eat first, and I don't think you achieve max fat burn rate as easy as hopping into warm up. I drink orange juice pre workout now. I have been warned against this because its acidic nature, but I have an acidic nature at 4am when I am drinking it, so it happens to work for me.
