You can account for 12 pounds weight loss in a week without much dehydration.
Let's say he burns 2500 calories a day, or 17500 in a week. If he has 500g of glycogen, subtract 4 calories/gram and we're left with 15500 calories. He's already lost 500g from the glycogen, and somewhere around 2000g from the water storing the glycogen, so he's down about 5.5 pounds. If the other 15500 calories are from fat, at 3500 calories per pound, he would lose about 4.5 pounds, for a total of about 11 pounds.
- cperciva 9y ago12 lbs = 5450 g. 500 g of that could be glycogen, stored along with 1500 g of water. That's 2000 Calories and 2000 g in total. If the remaining 3450 g is fat, it would be 31000 Calories, for a total of 33000 Calories, or 4700 Calories/day over the week. Not a reasonable amount! Taking your 2500 Calorie/day value, I get about 1700 g of unexplained weight loss.
