Gym on empty stomach

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.0 -
Yeah, I'm totally making up that reoccurring 2-3 hour thing...references cited. I guess there is no bending or recumbancy in exercise according to some "expert" opinion
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.1 -

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 ....0 -
I heard you'll get most benefits from it and personally believe that
As long as you have good diet, which mine is bad and good depending on the day and mood
If you're stomach is empty and you didn't have a good meal your heart attack risk increase exercising on empty stomach
source for all this?
All that is just common sense
Look it up it's out there
It's not one source it's just from a ton of stuff I've read
i was not aware that having an empty stomach increased your risk for heart attack ...again, do you have a source for that beside woo.com...?
Anybody is at risk for having a heart attack at any time
I can't go into detail but just look stuff up about diet and heart disease
It's very simple
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.
wow...
This is starting to sound like my teacher that made all of us in high school use the bathroom before getting on the bus because an accident could always happen and the leading way traffic accidents are from impact putting excess pressure on the bladder...0 -
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.0 -

yea, but did you have a heart attack?2 -
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.0 -

???? wouldn't "accident" refer to someone accidentally pissing their pants on the bus in this context? not a car accident?0 -
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.Mapalicious wrote: »saw a girl pass out at 10am spinning class 2 weeks ago, likely because she didn't eat beforehand.

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*0 -

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.0 -
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.0

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"?0
-
I'd assume empty stomach refers to calories or no (it does when talking about fueling endurance activities), so yes, milk would be food.0

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"0 -
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.0
