I once saw a calculation. If someone rode a bicycle from London to Bournemouth (UK), fueled primarily by beef steak, it’s actually more CO2 emissions than driving a small efficient car. That was years ago too, so likely gotten even better.
I believe a more vegetarian based diet still wins however.
But the traveler is going to eat roughly the same amount whether he rides the bike or drives so there is little marginal carbon impacts from riding while 100% of the car emissions are marginal (since the alternate scenario produces none).

the part I think you are missing is the human can only eat so much because it takes not as long to go by car or train as opposed to walking
People eating a wholely natural diet and biking on cleanly made bikes is carbon neutral, most other forms of travel aren’t and won’t be as efficient because of it.

It was the energy differential that was calculated. It was, originally, mostly a dig at how carbon inefficient beef farming was.
