1. Cooked ground beef macros

Hey all.

So last month I was getting ready to throw together some dishes with ground beef in them, and musing out loud about "hmm, I wonder how much fat is still there after I brown and drain it". My daughter, who had a science fair project due about 12 hours later and hadn't started it yet—she's about as good at "planning ahead" as I am—was like, "well duh, dad, you should just measure it and find out."
Duh. And, two birds, one stone. Not bad.

Conveniently, I happened to have 1-lb packs of 20%, 15%, and 4% ground beef on hand (from Trader Joe's, if anyone is keeping score at home).
So, like a boss, I used the science fair as an excuse to sit back and play iphone games while she did all the cooking and measuring.

Here's a quick summary of the procedure:
* We have a digital food scale, accurate to the nearest gram.
* Weighed out the raw beef for each sample (full package, empty package, subtract).**
* Browned the beef (in its own juices, no oil).
* Drained the beef and captured the tallow. Assumed the runoff was 100% fat (cause everything else evaporates).
* Weighed out the tallow.
* Weighed out the pan after cooking and subtracted out the weight of the empty pan (to account for extra fat that stuck to the pan and was thus also removed from the original).

Here are the basic results. If anyone wants the actual data tables, PM me. Because, well, it's a science project, so there are data tables.

THE RESULTS

80/20 Beef:
Starting macros: 23g fat per 4 oz raw
Drained + left in pan 15.4g fat per 4 oz raw
Ending macros: 8g fat per 4 oz raw (actually about 7.6, but rounded up)

85/15 Beef:
Starting macros: 17g fat per 4 oz raw
Drained + left in pan 10.1g fat per 4 oz raw
Ending macros: 7g fat per 4 oz raw

96/4 Beef:
Starting macros: 4g fat per 4 oz raw
Drained + left in pan 0.4g fat per 4 oz raw
Ending macros: 4g fat per 4 oz raw
She thought about rinsing it, but (a) who the heck wants to do that, and (b) there would be no simple way to measure the results of that.So yeah, there it is.

Basically, here's the deal in a nutshell:
* If you buy "medium" (85/15) ground beef, you're a spendthrift. Just buy the fatty stuff.
* The 96/4 beef only has half as much fat after cooking, and it also has another gram of protein per raw ounce. But honestly people, the difference is so small that only pre-contest people should care. And, you (dudes) want to be eating that kind of animal fat anyway, to keep your androgenic hormones high.Yay last-minute projects.

**Amazingly enough, we found that Trader Joe's consistently OVER-packs its ground beef packages... the ones marked as "1.00 lb" (aka 453 grams) consistently had between 465 and 470 grams of beef in them. That's about 4% overage, which means TJ's is losing about 10-15 cents of revenue per package.

2. Good info, thanks!

3. Man, I welcome the fat on those, I wish my George Foreman wouldn't get rid of so much fat

4. 93/7 turns out to around 5.5g fat per 4oz as well. Local stores have been selling 93/7 lately on the cheap...which blows cause I need more fat!

5. This is amazing! If I could give you all my rep points I would. I've been saying and doing this for sooooo long. The lean stuff is a joke. I wouldn't be eating ground beef during a cut anyway so what's the point? Save yer \$ and buy the bulk 80/20...

6. Nice info.

7. No joke I was just about to start a thread on this! Awesome Info and fantastic breakdown! I am now going to forget about buying the sirloin stuff and just cook the shat out of the regular stuff!
