    If you're stomach is empty and you didn't have a good meal your heart attack risk increase exercising on empty stomach

    Do what now?! *spoken in my thick Southern drawl*

    OP, personal preference for me. When I'm up at 4:30am, I lift fasted (aside for a couple of cups of coffee) and there's no way I could eat anything beforehand. Today I couldn't workout until 12:30 and I increased weight so I needed to eat prior to give me some energy - no way I could have done that fasted.

    I never work out on an empty stomach, I just don't give it my best effort if my stomach is growling, it is probably just a mental thing. I at least eat a protein bar in advance.

    you are also at risk of dying at any time too ...so make sure that your stomach is full at all times to prevent this .

    you can't go into detail because you are putting out a bunch of woo woo that makes no sense.

    You are kind of right, anyone can have a heart attack at any given time but what your saying about fasted cardio is far to misleading. Its highly unlikely a fit and healthy person is going to have a heart attack after a morning fasted gym session but if you have pre-existing heart troubles or heart attacks/angina runs in the family you may be more susceptible to having an attack fasted post workout.

    I'm interested in the heart attack risk/link but maybe going and searching for some proper studies could cause massive strain on the heart?

    Electrolytes can get low during a fast, we'd agree that right?

    These electrolytes are important for the signals to the heart. I think it's more risky for high intensity cardio than lifting.
    Here's a link...

    Since now "they say" coffee is good for the heart and can possibly lower risk of heart attacks, I guess mine as a pre-workout saved my life! Amazing!

    Unfortunately it doesn't work that way. In the Nutrition Debate board you have the burden of proof if you make such claims.

    Personally, after studying the diets of olympic athletes (Matt Fitzgerald, Racing Weight, Chrissie Wellingtons autobiography, and various articles and Joe Friel books, speaking to sports science nerds,and more), and the fact that I don't eat very heavily at night time, I prefer to load up with low fat protein and lots of carbs 2/3 hours before I work out. I run fast sprints for half and hour and lift heavy for 45 mins. Or I cycle sprints 30-90 mins, I need to have the fuel.

    I'm very glycogen depleted in the morning. I don't believe in fuelling the night before, use it or store it. I don't want to fuel my workouts with body fat as it doenst burn fast enough for what I do.

    I'm considering skipping breakfast on days when I don't workout or walk, but I'm so hungry by 6am I am wide awake.

    But they didn't mention exercise. I'm interested because as a vocalist we suffer a lot from GERD.

    I've never had a problem with it during exercise, even after eating or gels etc.

    You have to be lying flat and still for a long time for the stomach acids to work their way up.

    I believeyour quote is that it was optimal for exercise.

    Never said you made it up, I asked for a source out of curiosity. Easy on the butthurt ....

    I can wake up at 4:45 am be at the gym by 5-5:15 am workout for about 45-60 mins and be just fine however, I am famished by the time I get back home and a nice heavy breakfast is a must (that is for me of course)... it is recommended you have a snack with you if you do this - if at any point you start feeling dizzy or exhaustion seems to be taking over, immediately have your snack... remember that your body needs the sugars as a source of energy

    my favorite go to snack before working out is 1/2 toast with peanut butter, small/medium banana, and a cup of black coffee... that is energy to its best -- at least for me.

    I'm happy to do weights fasted but find I don't have enough energy if I don't eat a little bit before doing cardio. I usually just have a very small meal with protein and carbs so I have something to draw on for energy. My understanding is that when you train fasted you're in a glycogen-depleted state so your body uses fat for fuel. Someone told me that this is harder for the body to use (kind of makes sense as it's not the preferred fuel source) so it can make cardio/conditioning exercises feel harder (relative to your normal experience) . That's my personal experience and I train for performance I prefer to eat if I'm doing conditioning. I don't do long steady state cardio so it might be different for that.

    On a side note: to those who train fasted - do you find you smell like ammonia and does it worry you? I understand it's a by-product from the breakdown of protein. I'd love to get some thoughts on this as I've started to notice this over the past 6 months. I first noticed it when I did hot yoga but now seem to get it when I train weights fasted or do conditioning on a nearly empty stomach.

    saw a girl pass out at 10am spinning class 2 weeks ago, likely because she didn't eat beforehand.
    Or she could be eating too little overall daily. Or because she may have low blood pressure or have an iron deficiency. There could be lots of reasons if you don't personally know this person.

    Yes...congrats on figuring that out! You're a real sleuth.

    I chatted w/ the instructor afterwards who teaches her regularly, and that was her guess as well as someone who knows her better. *shrug*

    No, accident refers to car accident. My teacher was under the impression that most people that die in car accidents do so because of a ruptured bladder or kidney causing sepsis, and that the problem could be reduced by not traveling with a full bladder.

    I couldn't work out on an empty stomach. I feel sluggish and am unable to complete my morning workout if I do this and the gym staff would be picking me up off of the floor. If you can tolerate working out on an empty stomach, however, do so.

    What constitutes an empty stomach? Is it just food, or fluid too? I have 8 or so cups of tea with milk all morning, and don't eat sold food til lunch time. Would the milk be classed as "food"?

    I'd assume empty stomach refers to calories or no (it does when talking about fueling endurance activities), so yes, milk would be food.

    For the purposes of lean gains style intermittent fasting they say that anything over 50cals will break the fast. I don't know where they get that number from though.

    In terms of the actual fuel sources used, a little bit of milk in your cups of tea may not make a huge difference as your body will go through that pretty quickly so you may still be burning predominately fat instead of carbs as your fuel source.

    Please correct me if this is wrong

    Yeah I've read the exact same thing. Each cup is around 21 calories, and it's a big 500ml mug. So i can squeeze in two before technically "breaking the fast"

    I eat late into the night (11:30pm), so skipping breakfast isn't an issue for me. I've well fueled as I do sessions with clients from 9:00 to 11:00am, then workout afterward.
    Don't know why people don't think you CAN'T keep glycogen storage high enough for 12 hours before use. I'm sleeping for 8 hours (fat for fuel not glycogen) and the other 3 hours is driving to the gym and instruction. Hardly a glycogen depleter.

    I used to get that when I low carbed. Look up ketosis.
