Do fat people bonk?

[Amanda P]

I'm pretty skinny, and I have to eat like fury on a long ride to keep going. I nearly always underestimate just how much I'll need to eat. Is that because I'm not carrying much fat?

Do those of a plumper persuasion find they can eat less or go further before they bonk? Or does the body use every scrap of every other fuel around before embarking on metabolising fat?

Just musing. And it makes a good thread title.

yes we do

Do a google image search on "BBW" and that will give you an answer.
Maybe not the answer you were looking for, but an answer none the less.

Bonking is running out of glycogen isn't it? So not related to fat.

Are we going with the cycling definiton of "bonk" on this?

Err...yes.

In my case - much more frequently than when I was slim and fit. It takes a lot more energy to hump a big body about over the hills than a small one, and as pointed out above - fat is fine for slow, steady efforts, but it is glycogen that you want for intense efforts and that is in relatively short supply.

I pretty much know what I need to keep me going now so bonking had become rare. I have had it happen when I am trying hard to keep up with faster riders because I am working harder than usual and have less time to eat or drink.

I'm quite plump and bonk 3 or 4 times a week on avarage. My OH is quite skinny and bonks the same amount as me.

3 or 4 times a week? I am really feeling middle aged now :-(

Don't be daft! The more you bonk, the more you bonk. Just keep bonking away and you will soon have increased your avarage.

 

[middleagecyclist]

But the more I bonk the longer and more frequently I need to rest so my rolling average doesn't change that much. I just get sweaty and then cold by equal measure.

And I am geriatric!
