Oh, and I forgot my source for the grassfed burger nutrition.  I got the
data from Dr. Don Beitz of the Iowa State University Meat Science Lab. 
I can send a copy of the spreadsheet to anyone interested.

> 2) Daily caloric needs for weight maintenance -- a concept I'm frankly
> really not sure about due to Taube's research, but I'll give it anyway

> 155 pounds (per the Mayo calculator)
> 3) Daily protein requirements are about 100 grams per day for an active
> 42 year old man.  (Remember that excess protein is converted to glucose
> via gluconeogenesis -- see Rosedale)
> 4) Daily carbohydrate needs are ZERO (see Taubes, Atkins, etc, etc)
> 5) Omega 3 needs are at least 1 gram a day (see anybody)
> 6) Omega 6:Omega 3 ratio should be at most 2:1 (see anybody)
> 7) Also note that I'm not going to touch on calcium, other minerals, or

> burger)
> So how much 75% lean grassfed burger would be required to give you 2350
> cals per day?  1.75 pounds.
> How much protein would you get per day eating 1.75 pounds of grassfed
> burger? 115 grams or 460 calories (almost none of which would be used as
> calories)
> How much fat?  About 1900 cals/day.  (As I've posted here before, my
> experiments have shown that I don't want much fat at least early on in
> the diet and that I had a hard time getting enough calories, thus

> time for adaptation --see Phinney -- or my body was naturally trying to
> get down to a more natural weight level, as I could stand to lose maybe
> 10-15 pounds at the time I was doing the experiments).
> How many grams of Omega 3s? 4.7 (Dietary experts say to get at least 1-3
> grams.  One teaspoon of Carlson's fish oil gives you 1.6 grams)
> What is the Omega 6:Omega 3 ratio for grassfed hamburger? .81 (markedly
> better than the recommended 2:1)
> And how much would a grassfed burger only diet cost?  About $283/month
> or $9.50/day
