The body fat of an obeast can feed almost 1000 people Or one person for 1000 days. I like to play with numbers.  Lets take a typical 300kg eatbeast posted here for an example.  Typically, women have lower weight than men, so lets say a normal human female with 1.75 meters weights about 60kg. (BMI of about 19.6)  (That’s pretty much the size and weight of my mother currently. ) And a normal unathletic person carries around a energy reserve of about 10kg bf. So  300kg lardbeast - 50kg lean mass weight results in about 250kg of fat mass.  Since 1kg of body fat roughly equals the energy of about 7700 kilocalories, that would be about 1925000 calories at 250kg body fat. Divided by the standard calorie intake of about 2000 kilocalories a day, ( 1925000/2000 ) that amount of energy can feed 962 people for a day.  For comparison, the 10kg of bodyfat of the normal person  can feed about 38 people for a day. (10kg bf * 7700/2000) Any ketoers here by chance? :P  Bonus: You’ll also have protein with your meal, a skeleton of a person with 50kg is usually about 10kg.  So that leaves 40kg, and lets subtract about 5kg (rough) estimate for 5 litres of blood (1 litre of blood is not exactly 1 kg) in the human body.  And another 3kg for the fat that’s part of the organs and various cells (collagen and whatnot).  And perhaps another 2kg for good measure on the stuff that isn’t protein or fat. (matter in the stomach or the intestines) That leaves a good 30kg of pure protein (+ residual water weight, not counted towards blood)in terms of muscle, organs, brain matter, nerves and whatnot, which results in about 100000 kilocalories from protein. (1g protein = 3.3 kcal, 30kg = 99000 kcal) Considering the average keto meal should be about 80 - 100 grams of protein per day, 30kg of protein can feed 330 people per day. (30kg/90g) If we’d really stretch it for the 962 people above (also that number goes up if we include protein calories), everyone would get about 30 gram of protein together with their 260 gram of fat per day. (1kg fat/7700kcal energy * 2000 kcal TDEE) No worries, we don’t need the full 100 gram of protein every day, there are times when 30g/day is enough.  Dear obeasts, pray you'll never be stranded on a deserted island with me. Without looking for food, i'll have enough to eat for 1000 days.  Sooo... Do you wanna build a snowman eat an obeast?
