I hadn't heard it myself until recently.
I thought she was just a mad Scot who liked to look at poo, but it was after reading a bit of Ben Goldacre that I found out about these ridiculous claims she was making. The way he picks apart that particular example is hilarious, basically along the lines of
1. Chlorophyll requires light to convert CO₂ into oxygen. Your body will absorb this chlorophyll through your bowels. If there were any source of light in your bowels, then there would be something seriously wrong with you.
2. Assuming there was enough light in there for the chlorophyll to function, it would start producing oxygen. Lots of oxygen, in a warm environment full of methane. Might cause some complications.

You're still missing the 3rd part of the triangle
As long as you stay far from an ignition source you should be fine. That can be complicated to do if your belly is so thin/full of holes that light can reach your bowels.

Oh, I don't know
Put enough oxygen into an environment and you start to lower the ignition temperature...

Only to a point
We'd have to do some checks there, but if you add too much O2 you run out of fuel (or you increase the pressure in your bowels so much you might explode anyway)

At any rate
I think we can agree that the whole proposition is quite ridiculous and that Gillian McKeith is talking utter shit.

Yes, we can agree on that
