Boring but important explanations and disclaimers!
* - I kept things very simple, just looking at beef, bacon, cheese, bread, and milk, and using the nutrition info from Five Guys to calculate how much land is needed to produce that much protein and calories. Luckily for my GCSE maths, the numbers came out about the same, with an average of 58.6 square metres.
I know this is all very simplified – it doesn't differentiate between grain fed / soy fed beef, or organic milk, for starters. It also implicitly ignores the potential alternative usefulness of the land where this food was made: was it marginal uplands, or lush lowlands etc., and the positive benefits of regenerative agriculture.
If you'd like to explore all these things in a far deeper way, I recommend the brilliant Our World in Data site.
