Pre-AM cardio meal/snack - what do you eat?

I'm interested in the answers to this too...
Personally, I think having something small would be better than nothing.

I always eat at least an hour before I workout. You have to have fuel to burn calories.

I do what you do: work out right when I get up on an empty stomach. I'm usually swimming and burning less than 300 calories and don't feel weak. Then I eat as soon as I get home a good balance of carbs and protein, then a snack mid-morning, and then lunch, etc.

My swim is a HIIT workout. I do a few warm up laps, then 100% down and 50-60% back. Rest 15-30 seconds, repeat for 10-20 laps. Then a few cool down laps.

If I lift first thing (strength training), I do eat something like a piece of fruit, and then protein immediately after. But I usually lift after work.

Yeah, I kind of got beyond that body for life idea, don't think it's the wisest. If it were a 20-minute walk, fine, but for HIIT or similar, you need SOMETHING in the tank. I usually have a latte when I get up with 1/2 cup 1% milk (about 50 cals), 8 oz strong coffee and a teaspoon (20 cals or less) of maple syrup, and a little cinnamon. I can do steady state cardio with just this, no problem. If I'm going to do Insanity or anything more strenuous, early on, I also have like half an energy bar, typically between about 100 and 120 calories, and between about 5 and 10 g protein depending on the bar. Then I work out about half an hour later and don't suffer for energy. The thing, too, to remember is that if you want to work out your BEST, you need some fuel. There may be some evidence to show a higher fat burn for first-thing-fast exercise but it definitely is not the best way to improve your actual fitness and ability, which in the longer run will payoff not only in your body shape of course but also in all the other stuff you really should care about getting out of it...

If your eating right through the day then you have enough glycogen stored from the previous day to prevent any adverse effects, so working out cardio early AM on empty stomach is fine upto about 45 minutes, if its gonna be longer then have something first like a half bagel and peanut butter or jam, or a banana or something similar.

The fat burn in the morning is true however it takes a while for your body to adjust before metabolising fat for energy and even then takes around 20 mins of exercise before it kicks in.

in short, if 45 mins or less then empty stomach, if longer then something small and sugar based as aoppose to starch based carbs, if real intense workout like i did this morning then eat about 60 to 90 mins before even longer if you can.

For example, yesterday morning i went for a short fast 4 mile run and did it at 5am with nothing before then a good breakfast upon return.

today i got up at 5 and had oatmeal with banana and choc sprinkles, 2 eggs on wholemeal toast and fruit juice, hour later i headed out for a 12 mile run with hills carrying a pack.l.

I HAVE to eat a real breakfast before I go work out--close to 400cal. One day I ate like 200 calories, then went and burned off 400 on the treadmill. I went and sprayed my towel to wipe off my treadmill....and almost passed out!. I started making sure I had about 10g of carbs, and over 300 cal for my breakfast, and it hasn't happened again.

I'm doing intermittent fasting (16/8) so i train on any empty stomach and really dont flag for energy at all. I think like everything its all about finding out what works for you and what suits your lifestyle. Everyone is different and everyones body responds differently. If you feel crappy working out on an empty stomach then eat, if like me you dont then its not a problem

The empty stomach crowd says that hey if you work out on an empty stomach you will burn fat especially after a night's sleep. And if you eat food - you will just burn that first before burning fat and waste part of the workout.

That is correct. When you wake in the morning it's probably been at least 8 hours since you had something to eat. This means your insulin levels are at the lowest point for the entire day. So what is the role of insulin? What does it do? Insulin is the hormone that tells your body to store carbohydrates as fat. It's an energy storage signal. If you wake and then eat something before heading off to do your cardio your body's response to the food intake will be to release insulin which deters fat loss and encourages fat storage. Why would you want to put your body in a fat storage hormone state at the beginning of your cardio routine? That's counter-productive.

Eating also helps replenish your liver energy stores and this is your body's first go-to place to get the energy it needs. If you eat a 500 calorie breakfast before exercising you'll burn through 500 calories (depending on how quickly you exercise right after eating) of the food you just ate before your body finds the need to go to fat cells for energy. This isn't a total wash because you're going to be short those calories if you just burn through them and it will be as if you didn't eat much for breakfast. Still it's a better gamble to go ahead and initially call for fat calories up front when you know you're going to burn through them and your body is in the best fat burning mode of the day. It's possible that some of your breakfast eaten after the fact could be stored as fat but the overall effect (In my humble opinion) is a better scenario and opportunity for burning fat.

I believe that fasted cardio does make a slight difference in the fat burning effect of cardio exercise and over time, day after day, that slight improvement adds up to be a big advantage.

If you're doing strength training in the morning first thing then I would recommend having a little something to eat. A proper strength routine will burn though your glycogen stores and you'll probably be in a fairly low insulin state by the time you start cardio after the strength training.

The best response actually is this:

For the lean trying to get very lean (15% body fat or less for men, 22% or less for women), various strategies, including fasted cardio are probably going to be required to offset the mobization and blood flow defects.

But for folks who aren’t that lean yet, the folks in the middle range of body fat levels, it really doesn’t matter. The best time to do cardio will be whenever it will most consistently get done. If that’s first thing in the morning, fantastic. If not, also fantastic. It’s more important in this situation that it gets done than when it gets done.

Its not a guessing game, its pretty clear but the "bro-science" just wont die. Post sources not your guesses.

plenty of research, some of the more recent..... http://www.ncbi.nlm.nih.gov/pubmed/21411835

Eating before a workout raises EPOC for an extended time after.

I get up and run or ride my recumbent stationary bike in the mornings and all I do is roll out of bed, get dressed, take a few sips of water and go. If I'm biking it, I sip the water the whole time, but if I'm running, I don't have anything until I get back. Then I eat a greek yogurt and drink water.
