Running on an empty stomach

Yes, that was the only dispute, and i did post a few times in this thread prior to this one:D. Listen, this is not a personal attack against you, don't get all powered up, you have really good posts in this forum don't get me wrong mate. I just wouldn't want people to believe that during exercise your insulin levels are high because it's not true that's all to it.

re: personal attack. fair enough, I just don't like it when people do drive-by-shootings on posts where I don't see contributions. nuff said.

re: insulin... then I don't understand what I'm reading because I've gone over it again and it still reads the same to me. They way I understand it... "upon completion" of exercise insulin levels are high and with post nutrition workout, even higher.

If I'm wrong, I'm wrong but I'd like to read something that explains it to me. Doing a search for anything with the word insulin yields miles of articles on diabetes so if you have a reference I'll read it.

EDIT: to clarify, my contribution statement wasn't directed towards you, it was directed towards I love muscle, you just happen to come in after.

Go to the table for anabolic and catabolic effects of acute exercise and check what it says about insulin.
 
+2 Wow, that was pretty intense and much of it I actually suspected all along!!!!!

I'm definitely going to start pre-loading more....it helped a bit before and I bet it'll do even more!

Thanks Buzz! :D
 
HOLD ON NOW.......

I sent that article to my nutritionist Alan Aragon....and he sent me this:


He basically picked that article to pieces and explained where the author misinterpretted and distorted the data......

Just offering another perspective so we can all chew on info.

Ok, this are the Quotes, in italics, then Alan Aragon's underlined and then my thoughts on each one of them.

1. Replenishing Glycogen Needs to be a Focus of PWO.

I’m not just suggesting that glycogen resynthesis is not important following exercise, I’m flat out saying that for strength training it’s not even a concern! This is because it’s just really easy to get our glycogen levels back up, and timing is generally not an issue.


Right off the bat, how many ofwith it was 91% full recovery in contra us here are training for strength, & how many of use are training for looks? Westside Barbell in da house? We're talking about bodybuilding, where for most trainees, strength is a welcomed & almost inevitable side effect rather than the primary endpoint goal. I agree that quick glycogen replenishment is almost a non-issue for SOME powerlifting & bodybuilding protocols & phases. But without a doubt, most bodybuilding training goes on within the glycolytic system, & level of glycogen depletion in many cases is significant. Nothing is ever as simple as we'd wish it to be.

I think in this one, Alan is talking about elite bodybuilders and not the likes of you and me. I would agree with T-MAG on this one since we are NOT in the elite, i would say IMO that we are included in "MOST cases" scenario.



Quote:
Although one study showed that following endurance exercise, glycogen levels were replenished more rapidly when carbohydrates were consumed shortly after the exercise (Ivy, 1988), this is really of little concern to most of us. Unless we’re subscribers to Runners World, athletes in competition, or doing 2 a day workouts, why do we care so much about rapid glycogen restoration? After all, we’re mostly concerned with muscle growth, fat loss, and getting stronger.



Perhaps the author hasn't done a whole lot of work with precontest bodybuilders. It's not uncommon at all for precontest guys to be training twice a day. Believe it or not, many guys in the final 6 weeks of prep kick it up to 3 times (cardio morning & night + weights mid-day). Even with noncompetitive bodybuilding trainees, there's a lot of potential of overlapping muscular work, especially in the lower extremities, when cardio is done in addition to weights. Can't blanketly state anything here, it really depends on how Mentzer-esque vs Classical/Germanic the training protocol is, & what phase or goal we're looking at.

Again on this one Alan is talking specifically about precontest bodybuilders and 2 to 3 exercise bouts a day. That is too specific, it does apply to you and me, it shouldn't concern us, as clearly stated by the article.

Quote:
The most common argument is that the subsequent cellular hydration and swelling will have an anticatabolic effect on muscle. I don’t believe that this is possible because cellular hydration to the extent that we get with creatine supplementation has little effect on muscle protein synthesis or breakdown in healthy men or women (Louis et al., 2003).


*BEEEEEEP* Wrong answer. The Louis study he cited simply showed that protein synthesis in the immediate postworkout period may not be an aspect of creatine's anabolic mechanism. This does not at all refute creatine's effects coming in part from its ability to volumize cells. This study did NOT show that creatine doesn't work for its intended purpose for bodybuilding (size & strength gains). The researchers did NOT measure lean body mass changes, which is indeed the primary physical manifestation of creatine supplementation. Why did the researchers not measure LBM changes? Because, according to the researchers themselves, "the likely changes observed over such a short period of creatine supplementation with only a single bout of strenuous exercise would be expected to be below the detection limits of any available method." Talk about study limitations, the testing was done after 4 weeks & a single bout of training. Good gracious.

On this one Alan is spot on, this study's limitations are enough for everyone to say with eyes closed that the amount of training given to the subjects, including the creatine given was not even close to enough. A single bout of training and and creatine for 5 days only!!!
Taken from the article itself: Seven healthy men (body mass index, 23 +/- 2 kg/m2, 21 +/- yr, means +/- SE) performed 20 X 10 repetitions of leg extension-flexion at 75% one-repetition maximum in one leg, on two occasions, 4 wk apart, before and after ingesting 21 g/day creatine for 5 days. What sort of results did they expect? Nevertheless, we still don't have a clue about how harmful creatine can potentially be to our health in the long run.

Quote:
Surprisingly, one study showed that consuming carbohydrates after strength training only increased muscle glycogen by 16% more than when water was consumed (Pascoe et al., 1993)! With this information and the huge amount of carbs that we consume on a daily basis, we should have little doubt that glycogen levels will be maximized within 24 hours of the workout.


Okay, here we go.. 1st of all, a 16% difference in ANYTHING having to do with tissue reserves is a big proportion. For example, imagine losing or gaining 16% bodyfat. Imagine of you could take a pill that improved the amount of reps you could do in any given lift by 16%. Imagine carrying 150lbs of fat free mass, & increasing that by 16% (that's a 24lb gain). Imagine increasing your 16" arm by 16% (that's a 2.5" gain making your arm 18.5", not too bad). I think you get my point. To further support my point, the protocol in that study was training to exhaustion with appx 9 sets of 6 repetitions @ 70% of max on the leg extension. In bodybuilding training, 6 reps & 9 sets usually represents the low end, for both sets & reps for quads.

Ok, Alan is a bit overdramatic on this one, the study took samples after the first and second hour and what was given to the subjects was H2O to one group and CHO solution to the second group. After 6 hours the H2O group's glycogen content was restored by 75% and the CHO solution group by 91%, a fact that clearly shows us that, in a 24 hour period it should be expected a full recovery by the H2O group, and we are talking water OK? Oh, by the way, a 16% is not that big an increase regarding CHO consumption, it's a big increase in fat free mass though :D. Don't forget that we can only store 500gr of glycogen in our body so the dfference is not big.

So in other words, no, i don't think that Alan tore the article in pieces...no, not really :D:D

I like to believe that doing your jogging and/or cardio int he morning within 20 minutes of waking up is the best way to go for two reasons only though. I hear people often say it kick starts your metabolism for the day which is usually a good thing.

The second reason is because people often say that when your stomach is empty, your burning calories directly from the fat stores on your body and whatever in your muscles. However if you eat food and then workout, perhaps your burning energy from the food you just ate which isn't so bad, but it's not as direct as on an empty stomach to hit the fat stores.
 
I think what you're saying here is logical Amber, and I'm sure you're probably right on this, no questions there.

But IMO a person should consider whether they want to run to be thinner, or if they want to run to be in the best health they can.

I have no doubt that it's purely a matter of personal preference, if you're happier running on an empty stomach, by all means it definitely isn't going to kill you.

But just some things to consider. While it may be possible to burn fat from your exercise more efficiently this way, burning large amounts of fat is not necessarily a good thing. There's plenty of good evidence to show that the body can adapt to its new weight better and more smoothly when that weight is achieved slower. For people attempting to lose larger amounts of weight, the concentrated burning of this fat may increase their risk of having saggy skin once the proper weight is achieved.

Also consider that your body is going to need vitamins, and other nutrition in order to grow and develop the organs. The energy your body creates from fat is no substitute for having all the proper nutrients in your blood. So you should consider that if you exercise after eating, you may waste some metabolism on digesting food, but that metabolism will be carrying all the nutrition from that food throughout your body at a faster and more efficient rate, right when your body needs it the most, and this could help you get more out of your exercise.

So while I maintain my stand that it's personal preference of whatever makes you happier, I will say that you will still lose weight if you eat before exercises as long as you're doing everything right, and your body wont exactly gain anything by working empty other than possibly faster aesthetic changes.

I'm inclined to agree with you.....

Simply explained....when I read the article I found some of it rather interesting and surprising, so to be safe I sent it along to Alan just to make sure I wasn't about to change my routine for the worse. Alan's response was to say he long ago addressed this very article in another forum and, in his words, "tore it to shreds".

Have you ever seen a show where two lawyers each present their case....and each is amazingly convincing and has good points? That's what this rather seems like. Many authors take data & research and write articles based on their interpretations....and we, the common-folk public, have to then in turn digest it from there. Fed, non-fed, partially-fed...ughh!!!!!!

I guess, in the end, we each have to determine what works for us and just work with that....but it's human nature to try to understand and approach things in an intelligent manner. Who'd want to think that by eating they were defeating fat-loss (if your goal was to burn fat)....so it's out nature to try to understand and study this...and I've gotta tell ya; talk to 5 different nutritionist, trainers or dieticians and your answers will vary!!!!

actually the best way to kick start your metabolism is to eat :eek:
second reason is because people often say that when your stomach is empty, your burning calories directly from the fat stores on your body and whatever in your muscles. However if you eat food and then workout, perhaps your burning energy from the food you just ate which isn't so bad, but it's not as direct as on an empty stomach to hit the fat stores.
you never burn one source ie fat etc its a percentage of each,ok on waking fasted you might have a higher percentage of fat being burned,as long as you do low intensity cardio,but if your fuelled you can do a higher intensity of cardio and burn more cals overall.

at the end of the day it doesnt matter if your fuelled or unfuelled,if your on a defecit of cals over the day you will lose weight if your not you wont,it sounds simple :eek: thats because it is.
 
:argue: :action3: What's happening ? :action4:

Personally, I don't run on an empty stomach. Upon waking up, I drink milk, stretch a little here & there, brisk walk, jog and run. After exercise, I'll have a heavy breakfast....

:jump1:
 
I cannot exercise on an empty stomach; I usually eat an hour and a half before going to the gym.
And once I tried running on an empty stomach... it was the worst thing ever. I was so tired after and my day was ruined.
 
So your saying I should drink a soda before a workout?

Teeeeeerrible idea. The sugar will probably make you want to throw up.

And an insulin response won't necessarily inhibit fat metabolism. It'll just mean that your body will have more energy from the carbohydrates you just ate before it starts to fully dive into your fat stores.
 
Hi my name is hanny.... i agreed with phia try to run everyday for 30min and don't take junk food.

I like saying just do it when I play golf lol... it does not help me alot.... I like doing both if I'm doing longer than 30 min. of cardo.. I like to eat something simple carb. even eggs then wait at least 30 min. before I run. I'm on my way out for a super bowl run pushing for 10 mil. today but due to time maybe just 8 need to break away to color hair for bowl party... lol.... Happy Super Bowl everybody.......
:)
 
People are different if I eat before a 5k run i feel sick as and my run is much slower, same when i play football, my worst games have come from eating an hour before hand
 
It is not advisable to run in an empty stomach because eating in the morning with a little amount of food will help to burn your calories make sure you eat atleast an hour before running. Skipping meal is not always advisable to the person who is on diet.
