Hmmm... I just did some googling.  There are 4 things that have calories: Alcohol, Protein, Fat and Carbohydrates. Assuming the human that we are measuring doesn't have any alcohol in his/her system, and also assuming an average sized human (Human Body Statistics) 179.7 pounds if you average the average male and female, and also assuming this human does not have an excess amount of body fat or protein above the average, this human would be 12% lipid (fat), 20% protein, and 0.4% other organics (including a small amount of carbs, namely glycogen stores within the muscles and whatever sugar is in the blood at the moment or being used by cells currently). So if we take the fat portion of that, 12% of 179.7 is 21.6 pounds of fat. This is about 9.8 kg. Fat is 9 calories per gram. 9.8 kg is 9800 grams. 9800 x 9 = 88,200 calories of fat. The protein portion, or 20% of 179.7, is 35.9 pounds of protein. This is about 16.3 kg. 16.3 kg is 16300 grams. Protein is 4 calories per gram. 16300 x 4 = 65,200 calories of protein. Now for the small amounts of carbohydrates. Glygogen stores are about 600 grams average (The Role of Skeletal Muscle Glycogen Breakdown for Regulation of Insulin Sensitivity by Exercise). 600 grams of carbs X 4 calories per gram of carbs = 2400 calories of glycogen. Then we get to blood glucose. This depends on time of day and a bunch of different factors, but a normal glucose in the middle of the day might be about 80 mg/dL. You have about 5 Liters of blood in your body. a deciliter is 0.1 liter, so this is 800 mg per Liter of blood. Multiple x 5 to get 4000 mg total. Turn it into grams to get 4 grams. Multiply x 4 for calories to get 16. (wow this is way less than I thought). So add it all up: 88,200 calories of fat, 65,200 calories of protein, 2,400 calories of glycogen stores (carbs) and 16 calories of blood glucose (carbs) = 155,816 calories, give or take a calorie.  Now, it should be noted that Trump weighs way more than the average human. Around 265 lbs. so multiply 88200 calories by 265/179 and you get 130575 calories. Given Trump's body composition, I'd think that he'd be more lipids than protein. Fascinating shit.
