this kind of comment makes me want to ...

train for and run a marathon just to prove him wrong. Too bad I HATE running.

"there is no way in hell you can train sucessfully (to do well) for a marathon and be a low carber--I've been a runner all my life. If you must lower carbs, then 'carb up' a few days before your big runs or race--the body is made to function on glycogen during exercise, especially long runs."

From the ALC of course.
...no point to this, just

Someone pointed out in the same thread that there's no way, no how to stuff yourself so full of carbs that you'll be using them for energy throughout a marathon. When you think about it, how would glycogen last that long? I think the person who responded used 50ish miles, but even at 10-20 I'd think you'd be out. Confused

If my memory serves me, I believe most marathoners "hit the wall" at about 20 miles. I guess this is where the glycogen runs out. Those who can finish do so on sheer will. It seems to me that a runner who was keto-adapted would not "hit the wall". Not sure if I want to test that theory out myself, though. I get so bored on long runs. I might try a half marathon, though. I have done 10 miles quite easily. It didn't seem like going 3 more would have been that tough.

Let's see... this would be like saying that your car runs ONLY on electricity... because it takes electricity to spark the combustion of gasoline! Roll Eyes

Even a regular, heavy carb eater is going to start using PRIMARILY FAT for fuel after about 12 minutes of this type of exercise! And, up to this point, again with this type of exercise, are going to use a MIX of glycogen and fat (and more fat than glucose)! I don't know what idiot posted this, but they don't know a damn thing about physiology, that's for sure!!! The fact is, the muscle cells would be happy to use fat for fuel substrate all day long, and will if properly adapted to it. I wonder if this joker can even spell the word enzyme?! Laugh

Glycogen is needed for high intensity stuff like sprints and low rep weightlifting (anaerobic stuff.) For a marathon, fat is more than adequate.

I saw that guy posting over there. Roll Eyes What a moron. Yup

He posted this on the M&E thread:

First off, you do need carbs, your body chooses this as its primary fuel source because it is most readily available to muscles and brain--the idea stated that you dont need carbs is silly. Living in fear of carbs is insane. The wrong types of carbs should be avoided (the usual sugary desserts) but you will lose more weight eating small amounts of healthy carbs (oatmeal, brocolli, brown rice) than you would just sitting around pouding protein and fat. Why is the case? Because those miniscule carbs help you get through your daily workouts. I've been a CSCS certified trainer for years and I see tons of people lose weight.

Also, I'd like to add that if you actually do exercise during the 3 days of eating no carbs you will get to ketosis very fast, I used to hit it during the second day.

I agree, totally.

I have a new acronym that I came up with today which describes a colleague in my office who drives me crazy. DBI...dithering, blithering idiot! You would not believe how she wastes time, and time is money even in the health care field.

I was browsing and had to leave, the DBI is sticking his nose into EVERYWHERE and yammering on about the need for carbs.

This is one of the primary reasons, for me changing from a moderate-high carb diet, to this woe...I was not happy with my endurance level.

I have done some endurance feats, but they were always broken up into manageable chunks, throughout the day, with rest in between. Once I get over about 20-30 minutes, I am tapped out. I am hoping that once I fully adapt on this woe, I will have much more staying power.
ReddyMcMeaty

I haven't done any kind of running endurance stuff. The longest thing I've done was a 6-7 hour uphill (intense), or up mountain I should say hike with a few stops for water and sausage. It's SO much easier on lowcarb. It's like night and day!! Maybe not for someone who's eaten high carb for their entire life then suddenly one day stopped, but if you've been doing it for a time and are used to burning fat, even if you cheat here and there it's still much easier without the carbs.

Well.. I haven't exactly switched cold turkey to zero carb. In fact, I was high carb up until around 4-5 months ago, and then switched to a moderate carb level of around 100-120g (I know that seems really high here, but you wouldn't believe what I was eating before that). I went through some serious adaptation, even to get to that level.

Finally, I switched to zero, almost exactly a week ago, and I feel that I am already at the same energy level I was before, so I am very optimistic, that I will improve even more over the next few weeks.
