Go easy on the red meat; research is starting to show it can cause colon cancer in certain quantities. Use whey or soy protein for some (not all) of your protein macros.
I hardly eat any red meat. It's expensive, and there just isn't enough fat in it. Pork, fowl, and fish are more than enough options for hitting a protein target.
Ah, I forgot about eggs. Not sure how though; I eat at least one every day. They're so versatile, and they literally have all of the nutrients required to build a functional chicken. Nutrient density is an underrated metric.
Or, get your omega-3 from plant sources like flax and chia seed, and avoid eating fat-soluble industrial pollutants, like mercury and lead, found in fish.
I did a couple of months and quite liked it. Couple of downsides/notes.
1. I do a lot of sport (sprints/track & Field) and it's no good for the dynamic sports as I found out. Energy from fat explosive events because the free fatty acids can’t produce ATP quickly enough. Carbohydrate metabolism occurs faster that fat metabolism, refilling ATP stores quicker, and improving short range (10-60 seconds) recovery better than Fats. http://www.eurekalert.org/pub_releases/2014-06/uosc-fts06021...
2. You're thirsty a lot - just keep your fluids up.
3. Your partner may not appreciate your acetone breath
4. Eat too many nuts and you'll probably get an itchy bum!
