    I heard it's good to run early in the morning on an empty stomach as it will help burn fat better.

    Any thoughts?

    It seem unlikely that the fat burn rate would be different. However, if you run on an empty stomach your digestive system will not be diverting blood and oxygen away from your muscles.

    Consider that it's easier to run in cool weather. In Austin it can get hot quickly as the sun rises so, for that reason, early morning is a good time to run. You can run in 95F + heat, but not as well and you would have to be careful to avoid dehydration.

    I usually run at night before dinner for abut 5 miles and feels good to me depending on the time of year but do feel hungry when I recover and feel refreshed.

    I always run on an empty stomach. I can run much harder that way, and that does burn fat more effectively. As mentioned above, food in your stomach diverts blood to digestion and you can't run your best. I don't eat solid food for lunch if I'm going to run after work; I just have juice with whey protein.

    That may not work for everyone but I have a shoebox full of track and road race medals that say it works for me.

    Right.

    I've known guys who ran in plastic clothing so that they will be hotter and sweat more thinking that they will lose more weight that way. They will not believe that they'd lose more weight if they ran in cooler clothing so that they would not tire so quickly. Somehow some people think that when exercising sweat is an indication of effectiveness. Probably guys here know better than that.

    Fortunately I've never had to lose weight. I figured that it would be easier to avoid gaining too much weight in the first place rather than becoming to heavy then having to lose it.

    It is not advisable if you are diabetic. Some athletes load up on carbs, then follow with an energy drink. It is advisable to not dehydrate as mentioned.

    Do you eat breakfast? And do you make your own juice? Or? I have an issue making juice at work, I don't have long for lunch and store bought almost always seems to be loaded with excess sugars! I can't imagine not having a solid lunch and going for that long of a run!? My lunch to run difference is always at least 6 hours tho... Any suggestions?

    I prefer running on mostly empty. I need a banana or Kind bar for an energy boost. 4-5 miles and I feel pretty good afterwards. I just ran in serious wind yesterday (which I hadn't done before) and a mile in I thought I was going to die. I had to stop at my sisters for a pit stop, some water and peanut butter. Rough...

    I'm new to outdoor running, 5 months or so, but was a treadmill runner for a long time!

    I almost always work out on an empty stomach.

    Have you heard of Intermittent Fasting?

    Eat dinner in the evening then sleep, rise and exercise.....eat next meal 16hours after you last meal the evening before.

    Shreds you bodyfat.

    Google it

    MarvelBoy, I probably should have pointed out that I compete at mid-distance. My training runs are no longer than 3.5 miles. I have no desire whatsoever to run a marathon (why do people want to run far instead of fast???).

    On the rare occasions when I run a 10k, I do not have breakfast beforehand. But my normal breakfast - after my run - is a nice big bowl of Wheaties, with whole milk and raisins.

    As for juice, lately I've been drinking Ocean Spray's 100% Juice, which as the name implies has no added sugar.

    I'll have to give that OS juice a try. I generally run 4-5 miles, occasionally a 10k. But I'm not necessarily looking to do a marathon. Just be better each day. I find I lag about 1.5 miles in if I haven't had a little boost like a banana. I am going to give running on empty a try, tho I imagine I will not perform as well, I am interested in seeing what actually happens! Thanks for the tip~

    That sounds like fasted cardio, look it up. The theory is that it will help burn fat since you're body will need something for energy. There are a minimum number of hours you will not have eaten before doing so. It is important to use BCAA's during and after your cardio session so that your body will not turn to its muscle for energy. I did fasted cardio for a few months and felt like it helped me get leaner. However, doing cardio while fasted will seem more difficult because you don't have a ready store of energy to use. Your body will first use up its glycogen stores, then turn to either fat or muscle for energy. That's why it's important to use the BCAA's. My swims on fasted training days were always tough. My knowledge of this is only cursory so I'd advise that you look it up and find out if it works for you.

    I'm with bro4bro. Empty stomach (usually about 2 hours) when I run and run hard.

    I'm also not buying, assuming you're in shape and run frequently, that if you don't have some food beforehand you won't have enough energy to run. You sure that's not mental?

    If you run a much longer distance than you are accustomed to you may experience symptoms of low blood sugar. Thus, someone who has not run more than three miles will probably experience symptoms if he suddenly jumps to 10 miles; I did that a couple times. It's not serious, but one can feel a bit light headed and extremely hungry after doing it.

    I like to run on a food-free stomach an hour or so after waking. A cup of coffee, and I'm good to go. I typically run seven miles, four times weekly.

    I HATE running after eating (i.e., with undigested food in my stomach). If you do, your body stops digesting and diverts blood/processes to running (your body thinks it's for survival), and it usually makes you feel sick as the weight of the food, ever step, is pulling on the tissue holding your stomach in place.

    I have no idea if your body would burn fat faster or other complex issues like that, but assuming there is an added benefit, I would wager it's minimal.

    I did ballet for more than 10 years and it's so physically demanding that I think I only ate before class once, maybe twice, and I hated every minute of it. You, literally, cannot perform with a full stomach. All that head down, head up, turning and spotting, and you would first start burping, then get a wet mouth, and then be spewing chunks.

    Eat a good meal hours BEFORE any workout and you should be fine unless you have underlying medical issues as others have mentioned (e.g., diabetes, anemia, obesity, etc.).

    It's down to personal preference, but I've never been able to run well until at least 3 hours post-eating - 5 or 6 hours is better.

    Running on an empty stomach makes you faster cause you're lighter.

    And if you believe that, I've got a used interstellar spacecraft I'll sell you for cheap.

    I usually run on an empty stomach... not just because of burning fat, but just simply because I feel more sluggish if not. That said... a light snack is probably ok before a long run (banana or so)... but not running after a full breakfast ;0
