Working out on am empty stomach. Good idea or no?

I've been wondering this question for sometime now.

I workout at 5 in the morning. I literally get up, put on my gym clothes, have a glass of water, and head out the door to the gym. I don't seem to have any problems with my energy level or feeling too hungry to be able to workout. I make it through a tough workout most days and come home an hour and a half later and have my breakfast.
Does anyone have any insight in why working out on an empty stomach is a good idea or a bad idea?

Thank you in advance!

    It's 100% fine as long as you don't get lightheaded or anything during/immediately after your workout.

    I can't do it because I get dizzy, feel sick to my stomach and want to pass out. If it doesn't bother you or hinder your workout I think its totally fine.

    totally depends on you....

    I find I can't run/workout when I have an empty stomach but also cant run/workout right after a meal.

    Do what your body is comfortable with

    :drinker: cheers to you for being able to get up that early in the morning!

    Not a problem at all. I've run up to 20 miles on an empty stomach and often workout as soon as I wake doing strength training.

    On a Saturday morning I drink a cup of tea and head straight out for the start of my yoga class one hour later. For yoga, I find it is best to do this on an empty stomach as there is a lot of twisting and releasing of the internal organs and core muscles.

    I eat a light meal soon after.

    Similarly, I make sure my last meal was three hours before my Wednesday yoga class and any yoga work I do at home and prefer to eat a light meal soon after.

    When I do my bodyweight sessions, it isn't so crucial and can train soon after eating and seems to help with available energy.

    I eat a banana or boiled egg prior to working out in the morning. If you're not feeling light headed I'm sure it's fine either way. You'll want to be sure to eat right after you work out to replenish yourself.

    same for me. I usually have a banana and hour beforehand at the very least.

    What about the opposite? I tend to work out and NOT eat immediately after. Exercising curbs my appetite. Am I hurting myself if I don't replenish myself with calories?
  • Thank y'all for your feed back!! It makes me feel better to know that it's not going to hinder my progress. With that said, I have a follow up question, Will I burn more since there is no reserve to use instead?

    @jaycie: I would say no, so long as you are meeting around your calorie target and macros (proteins, carbs and fats) for the day and you are not feeling dizzy or sick doing it.

    @Meg: you won't burn more as it will still come from your existing fats and blood sugars and glycogen stores in the muscles, and be replenished when you next eat.

    Please stay hydrated during your workout and listen to you body. :)

    My daily workouts start at 6:00 am.
    Prior to start all I have is a BCAA tonic with a couple GTE caps. May be my imagination, but I notice quicker fatigue without them.

    Then my breakfast feast follows 2-3 hours later.

    Heres my .02cents. I run every morning for 60 minutes before eating anything. I sometimes go until 8-10pm before i eat my first meal. It is a very large meal (1000+ calories) I also eat about two servings of cereal before bed (500 calories) I sleep like a baby and I wake up feeling great and ready for my morning 60 minute run. Sometimes I may have a very small high protein lunch if i feel dragging, but i almost never feel hungry during the day. I suppose I have trained my body to this routine, but i love eating one large dinner versus a bunch of small meals that always leave me feeling hungry.

    I am up and out the door at 4:15 am. Usually run 3 or 4 miles of late interspersed with running intervals. I never eat before running in the morning. Causes me no issues at all. As long as you do not get light-headed, I cannot see that there is an issue.

    There is essentially no evidence that not eating just before you exercise makes any difference in how much you do or do not burn. If you are comfortable not eating before, then do that. In the long run it just doesn't make any difference.

    no. it's not like if you ate right before you would body would be using those calories either because foods aren't broken down into energy until it's digested and digestion takes longer than 1 hour

    It is really up to you. I'm also up very early, either 4am for the gym or 4:30 on run days. For me personally I eat a couple slices of whole wheat toast prior to working out or running because that works for me. I think as long as you feel fine and as someone else said, you aren't getting dizzy or lightheaded then continue on :happy:
