cooking does reduce the weight of a four ounce patty, but you can't use raw nutrition info for cooked meat is my point. let's say 4oz of raw meat cooks down to about 3 oz of cooked meat. most that ounce difference is water [no cals] and a little bit of it is going to be fat. if you enter the cooked weight [3oz] with the raw nutrition info, it's going to reduce the number of on paper calories by 25%, but what you're eating isn't actually reduced by that much [again, most of what you are removing is water, not anything with calories].
let me put it this way. i'm going to use 95/5 beef as the example because i can more easily find the info.
if you start out with 4oz raw, that's 152 cals and 24 grams of protein. if you used the baked info for 3oz of 95/5, that's 148 cals and 23 g protein. that's pretty darn close. but if you use the cooked weight [3oz] and input that as if it were raw, you're going to see 114 cals and 18 g of protein. and the last time i checked, nuking something in the microwave is not going to take 6 g of protein out of it with the water. so if you're inputting raw nutrition info with cooked weights then you are underestimating the calories that you are actually eating. because most of what you are taking out of the ground is water. yes, a little fat, but it's mostly water, which is why if you are weighing cooked you need to be using cooked nutrition info.
