I haven't been watching Dan's videos for very long, I stumbled upon them and started watching them recently, and for the most part I really enjoy them. He's got a really good attitude and outlook on life. Just one problem: I'm pretty sure he's undereating big time. I know Harley made a video about this, but I don't know if he understands how much fruit he should eat! You guys might be familiar with the videos he's been posting about his cross country bike trip. Now, cycling like that burns major calories, so you've gotta be packing 'em back in or you're going to bonk out big time.
Check out this video, where he does like 15 hours of riding on just 30 bananas:
Now, if we do some quick calculations, you can see he's in the negative big time. I know this isn't completely accurate, but it gets us in the right direction: If you take a 150 lb. man and he rides his bike just 10 hours at 12-14 MPH (which is much less than Dan actually did), he'll burn up just shy of 6,000 calories, just on that physical activity alone. Not factoring in his basal metabolism or the fact that he was riding straight into a head wind for most of the ride.
Towards the end of the video he mentions he took a supplement, and when I checked it out it contained ginseng and other herbal stimulants. Something like that is definitely going to burn him out too.
In this next video, he mentions that he did an entire day on about 2 gallons of carrot juice, which would be about 3,000 calories worth according to CRON-o-Meter.
When I see someone walking down the street and they don't see the manhole they're about to fall into, I say something. Not because I feel obligated to, but because I truly want to see people be happy and healthy vs. burned out and sick. I've reminded my dad (who's severely diabetic, type 2) that he could reverse his diabetes in a week or two if he made changes in his diet/lifestyle. So far, he's done nothing, but at least I know he got the information, from then on it's his choice.
So let's all send Dan some advice on how to get his carbs in at his "Ask Dan" section on his site here.
His cross country bike trip is really inspiring and I think he's spreading a lot of good information, just not the 100% whole story (like eating enough calories from fruit!). I don't want to see him going off the deep and and binging on Reese's Peanut Butter Cups again!
I think Dan is learning that if you want to have high cardio or high muscle then you need to eat a lot of carb cals each day. Same holds true for high vigor.
For someone that doesnt have a history of bike touring, DTM is doing a premium effort.
Bike touring in the US is great cos if you bonk really bad in a day, you can just find a supermarket and restock and have an easy day the next and keep on rolling. Thats the beauty of bike touring, there is no clock or overall classification so you can ride 10 mins a day or 10 hours a day and it doesnt really matter.
Yeah, you guys are right, if he does bonk out he'll learn from it and hopefully do better next time.
I was just really concerned because it's not really the same as hitting the wall three quarters through a marathon because you didn't eat enough carbs, it's more like chronically undereating by thousands of calories, and that can spell severe physical and psychological issues....we definitely all make mistakes, but if I had someone stop me before I made the mistakes I've made in life, I would be eternally grateful! The information I've gotten from members of this site actually has done just that!
He supplements. And he also eats >10% cals from fats. Cool guy though.
Good point Diospyros, long aerobic activities like that would burn a fair bit of fat. But look at Dan, he hasn't got much fat to burn!
Maybe I'm overreacting a bit, but I've seen and experienced the effects of undereating, it's nothing to mess around with. I just didn't want to see it happen to Dan if it could be avoided, he seems like a really great guy.
