I don't know a lot about fat helping w/alcohol. But I wanted to let you know that while not a huge source of fat, your 95/5 lean ground beef does have substantial fat in it.
95/5 that the grocery store uses is a by weight measurement.
However, 1 ounce of 95/5 ground beef has 38 calories and 1.4 grams of fat.
1.4 grams of fat x 9 calories per gram = 12.6 calories.
12.6 calories of fat divided by 38 calories total = .33 = 33% of the calories are fat.
While I know that 33% of total calories being fat is low for primal eating, I just wanted to point out a misconception that a lot of people have about lean meats.
