The relationship between body fat percentage and protein percentage of energy is a cubic relationship with an R-squared of 0.99.

“what we see is that fat scales linearly with body weight okay so the larger the animal the greater the fat percentage is so let's talk about that a little bit but so squirrels have about four percent body fat by weight and the balance is protein because mammals generally don't store carbohydrate sure the carbohydrate that is found in muscle deteriorate sure is metabolized through rigor mortis after the animal is killed so all any available carbohydrate and muscle is gone the liver contains about three to four percent glycogen by way and it does remain after the animal dies but three to four percent of you know if you have a 200-pound deer doesn't amount to very many grams of carbohydrate at all it's practically none right so basically the equation that you're looking at now is fat to protein ratio and in our 2002 paper we developed those cubic relationships and so what I did to develop those cubic relationships we took fat percent by weight and we plotted it against fat percent by energy and so I guess probably you could call that up and you can see it's an amazing powerful relationship we had to curve fit the relationship and it's a it's a cubic relationship and it has an R of 0.9 and r-squared of point nine nine and we use hundreds of samples so those are that's that's that's a powerful relationship that we see with nature yeah okay so it's and these are home carcass analysis so what we saw with”
