Eating or not eating before working out, does it help?

I've read a couple of articles lately regarding working out on a completely empty stomach and wanted others opinion on the matter.
A few sources stated that when you workout on an empty stomach you burn a different kind of fat vs. when you workout having had eaten with in a couple of hours. The articles basically stated working out first thing in the morning without any fuel is more beneficial for fat burn and weight loss.
Anyone tested this? Thoughts?
I've tried it and find it challenging, my body is sluggish because there's no fuel. But I'll suck it up and push through if in fact it's really beneficial.

    If it you're finding it challenging and feel sluggish compared to normal, I'd say that's your answer, if you're not feeling good you're probably not performing well. From what little I've read it's aimed more at those with lower body fat % when trying to tackle the last stubborn bits to lean out.

    Funny, I was just having this same conversation with my bodybuilding competition group. I have always been of the school of thought that it's important to fuel your workouts and I had done that for a long time. I always made sure to eat a couple of hours prior so the food wouldn't bother me in my belly and all that... I read a while ago that a fasted workout doesn't necessarily burn more calories or just fat calories, etc. But a few weeks ago I began my competition prep and I have to tell you... when I do my fasted workout in the morning I am absolutely on fire! I have a ton of energy and amazing strength to lift and do cardio and tons of stamina! It kind of reversed on me. When I eat first or even if I just have a shake I feel sluggish through my workout. So I am switching to fasted from here on in... :smile:

    It is not going to make a difference in your overall weight loss and really comes down to personal preference. Your calorie deficit is going to be what drives weight loss.

    Plus, if eating before exercising allows you to keep up with the exercising, it is going to be better for your overall fitness than would going without eating and then not being able to perform well.

    I mainly work out in the morning with only having had coffee. My energy varies, but either way I only get about 30 minutes to work out so that's not long enough completely wipe myself out in any scenario. I am usually energetic once I get to work and still don't eat for another 2ish hours. No idea about the fat burn though.

    It's personal preference really.

    I do fasted cardio most of the time as I will get cramps..however I do eat something a couple hours before most cardio...(unless it's first thing in the morning in which case it's fasted)

    Lifting I do when I feel like it but I do try to do it before I eat my dinner but I usually have something small to eat about an hour before.

    I work out first thing in the morning with no food (I'd throw up). Works for me not for others. I have also noticed that if my dinner is deficient in protein it is harder to push myself the next morning. I can't say I've noticed any more loss than I did when I worked out in the evenings.
    I think the idea is more for cardio than strength training too - Fasting cardio is what they call it.
    Do what is best for you - phoning it in while fasted vs kicking butt because you have the fuel your body needs. I'm guessing that option two is going to get you to your goals faster.

    I usually work out in the early afternoon not long after lunch. I really don't think about it as far as whether or not I eat first. I go by how I feel at the time.

    I've recently read an article that says that not eating before a work-out will force your body to burn the fat and calories already you have. It says if you eat that you will burn off the fat in the food and not off your body. And it says that eating after while your body is working hard helps keep burning that food.

    I would agree that it's personal preference. For instance: I am doing the C25K challenge, and find that I prefer that in the morning before breakfast (I run outside and locally to me). I go to the gym in the evenings after dinner, because again that suits me. However, I have to leave at least 30-45 mins, ideally longer, between dinner and starting exercise in order for me not to feel sick/vomit.

    I'm losing weight because I am eating at a slight deficit. That is the key more than anything else.

    The clip linked below is of a very small scale study that suggest there is a difference, so you might find that interesting. However, remember it is all personal preference. Do what feels right to you, not what someone else claims to be the key to burning more fat.

    I would also agree that it is personal preference. I workout in the morning or early afternoon with no food. I never eat before I workout, I always get cramps. My boyfriend on the other hand, can eat dinner and go workout right after.

    Try both ways over the course of a week or two and figure out which works best for you. I personally cannot eat before a workout because I get sick to my stomach and have, on a few occasions, thrown up while running.

    Sometimes I bike to work and eat my breakfast here. It's more a case of waking up not-that-hungry and deciding to delay eating until I am hungry to make it easier to get to lunch without snacking.

    I don't think it helps my performance (but I'm not a performance athlete, I'm just a commuter). I don't think it matters to weight loss, other than as a strategy to begin eating later in the day and perhaps end up eating less overall.

    I do both--a few mornings a week, I workout before 5:30 am and don't eat, and the other times, I will have a light breakfast first (half a bowl of oatmeal and a tsp of peanut butter and a coffee) about a half hour beforehand. I do feel more energized with a little food in my stomach, but I can still get in a rigorous workout without food. UNLESS I totally cut carbs the previous day (rare) and in that case, I need food first.

    I think it's more of a personal preference. Gauge your energy levels. If you need something to eat before workouts, go ahead and eat. I know I have to have something in my stomach before I workout, even at only 30 mins. If it's been a long time since lunch or I ate particularly light that day (I work out after work), I'll have a banana or a piece of cheese or something just prior to going to the gym. It helps me maintain energy for the workout.

    Personal preference. I used to think you shouldn't work out on an empty stomach (I just assumed I would get light headed or something), but have actually found I perform much better that way.

    I used to have a banana or boiled egg before morning workouts (I eat nothing before afternoon or evening workouts), but then I was lazy and didn't get up early enough and got out of the habit, especially after I realized that it really doesn't change how I feel during the workout.

    See what you like better- I workout fasted in the morning because I don't like having anything on my stomach or I get nauseous. My husband can't function at all without some breakfast first. So we just do what works best for us.

    I get a lot of awesome advice on the forums but in the end, a lot of it is trial and error to see what works best for you to get the results you want in a safe and healthy way. But learning to listen to your body is a critical part of weight loss and exercising, so when you start to understand what feels best to you, results will come even faster.

    If I'm trying to burn fat I'll try not and eat about 2 hours prior. If I'm going to be lifting heavy I will eat pretty close to the workout...protein shake and some carbs.

    I do it either way. Depends on if I'm hungry in the morning or if I've pushed my workout to a later time than normal. I have never noticed a difference in my energy related to this.

    Rather, I have noticed that the time of day that I workout is more important for me. If I workout in the morning, I feel more energetic than if I leave it until evening.

    It makes absolutely no difference for weight loss. While it does cause you to burn more fat during exercise, it will all balance out by a few days later. I sometimes go for a bicycle ride on an empty stomach because I intend to stop at a pancake house before continuing my ride. So, the biggest advantage for me is that it let's me eat more when I get there.

    I sometimes do cardio on an empty stomach, and even more rarely, I will workout on an empty stomach, but it usually has more to do with time of day and if I have the "calories to spend" or not. If I know I'm going to be doing anything intensive I make sure I eat a little something an hour before hand because I don't want to, you know, fall and die from being weak of hunger :)

    Otherwise I don't think it makes much difference for fat loss. There are theories that fat burning is more efficient after glycogen stores are burned out, but you get the same amount of over all burn regardless of meal timing. It all falls into calories in vs calories out.

    I agree with this. I drink a cup of coffee before I work out. When I did bootcamp int the morning years ago, I would either have a small piece of cheese and a pretzel or a pre-workout formula. I honestly think when you work out and if you need to have something in your stomach are personal preference. I prefer working out in the morning to get it out of the way and to jumpstart my day. There were times in the past I worked out after work because thats what I could do. You just need to pick a routine that works for you, thats whats most important.

    I've heard about fasted cardio, but I'm not sure if it helps much.

    I'd rather have a snack 30min-1hour before the gym so I can actually do perform. No point in doing fasted workouts if you can't give it your all and work as hard.
