Unfortunately, I need to track calories.
I buy 100% grass fed ground beef from a farmer here in Oregon.
Is there any way to figure out an accurate estimate how many calories are in an ounce or a pound?
The farmer does not know unfortunately.
100% grass fed beef is usually leaner than grain fed beef, but one of the best ways to tell is to brown some up and see how much fat is in the pan. If there is quite a bit, it's probably 80%-85% lean. If very little comes out, it's probably closer to 90% lean. Once you figure out which it is, you can use any nutritional database (Fit Day, SparkPeople, USDA, etc.) to get the nutritional information.
From what I can tell, they vary slightly, but are probably around 85% fat.
Also, in tracking, remember that nutrition information is per RAW serving. I have found that usually 4 ounces of raw ground beef cooks down to 3 ounces of cooked (so long as you haven't added other things in the cooking process, like onions etc.).
