Grilling the fat out

[MrCyp]

How are you supposed to know your meats fat content if you grill it on an outdoor grill? For example I eat a lot of turkey sausage which has 18g protein and 8g fat per link, but there is no way its 8g fat when its dripping down the grill. Is there a rule of thumb on this or an estimated amount that dissapates during grilling?

There's no way to really tell... But I'm guessing for turkey sausage on a grill you'll go from 8g to 5 or 4...
