"Calculation"? There's no "calculation" in the source you cite, simply an assertion:
"Calories of fossil fuel expended to produce 1 calorie of protein from beef: 78 "
...with no source attributed. FWIW, my vegetables come from my garden, which I till by hand and fertilize with composted horse manure from a friend's horses, and my beef is local grass-fed. My life ain't fossil-fuel free, but I have a strong dislike of simplistic sound-bite "facts" like this.
