I think that there is 25g or so in 4oz. regular ground beef, more if it is lean. So you are looking at ~100g or more, depending on what kind you have. And a sh*tload of fat.
well thats good to know then, i never really can determine the size of something by how many oz's it is, i never go by that. but since it was a treat i won't even think about how much fat was in it cause i could only imagine
