Oh my gosh! What did you just read?!?!?!!?
That's right! Eat a freaking poptart.
Before we go into this further, step away from the pastry if you are trying to cut or lose weight.
For my muscle gainers and maintainers- READ ON:
There are TWO times a day when your body needs simply carbs: first thing in the morning and after your workout.
Let's break it down, in the morning you are "coming off a fast" aka however long you slept the night before. So, at that time you want a simple carb source and a quick digesting protein source. But wait, if you plan to do morning cardio, skip the carbs and have a small protein shake. When you're done, have your carbs and protein.
After your workout! Eat that damn poptart people! This is CRITICAL as it starts the whole recovery/muscle growth process. Following a HARD workout, your body is severely depleted of glycogen and glucose.
During the workout, hard working muscles use glucose (usable energy) and glycogen (stored energy) for energy. There is a point at which blood glucose levels and glycogen levels get so low that intense exercise can't continue. AKA there isn't enough available energy for your muscles to use.
What happens next? Your body secretes cortisol which your body's stress hormone and it has very catabolic effects. Cortisol eats the muscle tissue that you have for protein and converts it into glucose. So the result is a loss of muscle tissue.
Please only follow this if you are lifting or doing HIIT and you are pushing yourself to the MAX. Do not think you need a poptart after lifting the pink 5 lb dumbbells for half a set and then dragging yourself on the elliptical and reading a magazine.
