Breakfast before or after morning jog?

    Hey guys,

    this question has probably already been covered before, but I couldn't find a good match.

    I've recently started jogging again, more specifically I'm starting HIIT training so as to increase my respiratory capacity, and also since it's quick to do before going to school in the morning.

    I was wondering what you guys would recommend as the best time to have breakfast: if it should be before or after the run. I've heard different theories.

    Some say to eat after the run, so that you burn off fat during the run, and then replace it with proteins from the breakfast. (ie. fat reserves are used up)

    Others then debunk this theory by saying that your body goes into starvation mode after a few days and like clockwork during the run will do its best to hang on to the fat reserves for energy later on. Then the breakfast after the jog immediately is used as energy to replenish the body. (ie. breakfast is used up)

    For now I'm have my breakfast 45mins before my run (oatmeal cereal, yogurt, and a fruit). I was a bit worried that I might get sick during the run with a full stomach, but so far so good.

    What are your thoughts?

    After your run, but if you need a little energy boost, eat a banana before heading out. What you are eating now is excellent for post-run breakfast

    But what do you guys think about eating before? What would be the effects of eating before the run?

    And what about this theory of the body going into starvation mode if you eat after?

    Your body doesn't go into "starvation mode" when you eat after your run. I don't know who gave you that misinformation, but its not true.

    If you really wanted to eat before, I would eat very lightly just to hold you over (like 1/4 cup of your oatmeal), and drink something with like 10g of BCAAs. Then eat breakfast afterwards.

    When you eat beforehand you're basically telling your body to start digesting food, then you start running and then you stop digesting and its sloshing all around in your stomach. You're also breaking your nightly fast so % of energy from fat used for the run will be lower than if you were to run fasted.

    My best friend told me about it. She's a nurse and is learning medicine too. I just wanted to run the info by you guys to see what you think.

    I eat before too. I've never left the house without breakfast. But I must say that my breakfast consists mostly of fruits, nuts and yoghurt.

    You`ll have to work it out for yourself as there`s no hard and fast rule on this.

    For me, I eat before a run or exercise as I can`t function on an empty stomach; but well before, at least ninety minutes as the full version gives me cramps!

    Good to hear there are guys who eat before too, and it seems to be working out well for you too.

    For me its always a banana (or some kind of fruit) before, and a meal after.

    ^^^ What he said ^^^

    I don't often run first thing in the morning anymore. Man does it suck to get old... but typically it's an after-work run around town before having dinner.

    But when I DID used to run first thing, I never could do it on an empty stomach... just something light but with enough natural sugar/carb to fuel you before you head out.

    Couldn't agree more. That's exactly my routine as well.

    Oh geez LAMOOOO

    To the OP: I am studying medicine (trying to at least). All I know is that you are very rarely going to get a stomachache from eating and then working out (unless you are a pro Olympic ice skater or the like).

    Unless you are one to throwup after workouts I would recommend eating something like a piece of fruit BEFORE and then your full breakfast AFTER

    I'd do my exercises with more energy if I have some little carb before.
