working out on a empty stomach in the morning?

gabriela182

so, i have read some mixed reviews on this. i have heard that working out before breakfast is a good way to burn "stored" fat as apposed to burning the calories that were eaten before working out. And then I have heard that its a terrible I idea and that you should eat before you work out.
I'm looking to burn more fat regardless lol I'm just curious on what I should avoid doing...

Im going to assume its not a good idea because you need that first meal to start your day off.

This was in a topic yesterday, in my experience the only two things you should avoid doing are over eating and skipping workouts.

I personally like working out on an empty stomach first thing in the morning and have never had any negative effects while lifting heavy and doing at least 30 minutes of cardio at the end of the workout. I have gone as far as running a 10K on an empty stomach(except for water) with no ill effects.

Today, life got in the way and I ended up having to workout at 4:00pm and therefore did so after eating lunch and a small snack before the workout.

I noticed no appreciable difference in my energy, strength, or endurance.

If you are prone to blood sugar problems or feel that you need/want a meal to get rolling in the morning then do as you please. No matter what your body will burn what it has available and the food that you put in right before your workout does not become available immediately anyway. I would say it is highly unlikely that it makes much if any difference other than in blood sugar levels.

You do not need to eat a lot; having an apple or half of a banana will do the trick. You need a little bit of carbs to be able to push yourself. Your post workout meal will be very important; lots of protein! All you need is about 50-100 calories.
When I wake up in the morning, I am starving so if I don't have a small snack, my workout suffers; feel dizzy and nauseated.

I will usually just eat an apple if it's an early morning workout. Anything more than that and I'm going to be visiting the trashcan during the harder cardio.

I feel sick if I eat before I workout in the morning. It isn't too bad if I workout later in the day as long as I haven't eaten for 2-3 hours. I don't eat or drink anything, go for my run or walk, and then get home and eat.

I generally do work out in the morning on an empty stomach, but it is usually low impact cardio/aerobics. I have heard you should eat something like a protien & carb before and a carb after (within a hour on either side). So something like an orange & some nuts or jerky. But I can't remember for certain which way you were to eat them, it could have been switched so that the protein & carb were after. The idea is you give yourself "fuel" for the workout & to replenish after.
Best of luck.

Your body will pull it's energy from what you eat first then from stored fat. Fat is the "back up in case of famine". So look at it this way. If you've been in a sort of fasting state all night while sleeping and you go work out then you are working out on the energy from fat stores.

so i guess it just all depends on the way your body works

Pretty much, If your metabolism is cranked up high enough or if you get up early enough to eat and have a meal digested prior to your workout then get it on.

I try to be out the door as soon as I am able to get breakfast into my daughter. In my experience vigorous exercise right after a meal is generally conducive to me not feeling well at some point during the workout so I prefer to have nothing more than some amino acids in water intra-workout and sometimes a pre-workout supplement as an eye opener.

I agree with the comments above. You need a little something before working out and your body supposedly metabolizes better if you can eat some protein within 30 mins of waking. Protein is hard tho prior to a workout but if you can its a good way to get that fat burn going. Just do what your body feels best with in the end, but personally I prefer to have something light in the mornings before I work out (protein shake, some nuts, carrots, etc).

I'm often an early morning gym person too. I just have a very light snack (like a piece of fruit for example or small bowl of cereal) and then after I will have a more substantial breakfast part 2

No science to prove that.

Keeping calories constant, I don't think there would be any appreciable difference in fat burn. So do what helps you feel and perform best.

This. I also personally workout first thing in the morning before eating. I'll workout at about 10:00am and not eat my first meal until 12:00pm. I do eat up until 11:00pm at night almost every night.

ETA: I actually do feel a difference in my gym performance in the afternoon even though I have eaten more recently, so I prefer fasted workouts in the morning.

My weight training professor always used to say....if you don't eat anything and workout you have nothing to burn/work off.

Even in a "fasting" state, most people still have a decent amount of stored glycogen. And even if you do burn more fat, a) it's a tiny amount and b) it makes no difference because even if your body does burn a (minuscule) greater amount of fat during exercise, it will burn less in the hours afterward. In the end, it makes no difference. Eat the way you need to fuel your workouts.

I prefer to workout on an empty stomach. I feel better afterwards, and from what I understand, If there isn't any excess glucose in your blood to burn (from the breakfast ) when you're working out, you will go straight to burning fat. Some ppl prefer to eat before, though. Listen to your body and do what feels right for you.

jennifer_417

I think it depends more on how it makes you feel. I used to workout first thing on an empty stomach, but it would occasionally drop my blood sugar and I would get dizzy and nauseous, not optimal working out condition!

Not true.

darkguardian419

It's personal preference. I prefer to work out fasted, so I don't have anything to throw up (on cardio days). However, I don't see diminished returns from not eating. If you do better if you eat, then eat. If you feel better doing it fasted, then don't eat.

gabriela182

i guess everyone has their own preference

aelunyu

It's true! overall food intake and whether your are in a calorie deficit is way more important than if you work out on an empty stomach. I personally hate breakfast (if you check my logs you'll see I don't eat it), but my workouts are before work, empty stomach.

I have never had problems gaining muscle or losing weight doing that, so it really shouldnt matter!

kaltey

I really think it's personal preference. I workout in the mornings and don't eat breakfast mostly because if I do it gives me heartburn.

galenofedgewood

I generally feel ill if I'm pushing hard on cardio with anything in my stomach. It's probably from all of these years in the service and not eating until after PT is over. /dunno

disdatdude

That's when you should get your protein (powder) drink on 20 mins before or 20 mins after.

Tdacks

Count me as no food before the workout, because it makes me queasy and gives me heartburn. I can't even drink much water, because then I feel it sloshing in my stomach as I run. Ugghhh. :sick:

I used to know a young guy when I was in the Air Force who ate a huge pancake, sausage, oatmeal, etc. breakfast as we were waiting for PT formation. Seriously, he would go from chowing down to running amazingly fast 5 minute later. He was also extremely thin and ate huge meals, so his metabolism must have been through the roof.

My point is that there is no rule, and anyone telling you there is has been misinformed.
