Effect of Grass-fed Beef in Quantity
 
what would be the likely effect -- blood lipid profile, mass gain, body composition -- of eating around 2lbs of 87% lean grass-fed beef per day along with vegetables and fruits, and the usual healthy fats?

Obviously I would vary the protein content a bit with fish, but let's assume that grass fed beef is the primary source of calories.

I have never looked beyond the how does it make me feel to the actual medical results.

I get in a rut and will eat a couple of pounds of chicken in a day than the next day I will eat a couple of pounds of ground turkey, the next day lean ground beef. I believe I feel better the days that I eat like that than when I don't.

2lbs is probably around 1700-2000 calories depending on the meat. But I'm assuming that having no carbs, the insulin effect is muted, and it should help to build lean mass?

The days that I feed like that I will eat a 4 - 6 oz portion every meal which ends up being 5 to 6 times per day. Lets look at the numbers.

6 x 4 ozs = 24 oz so that is a 1.5 lbs at 6 oz portions it comes out to 36 oz or 2.25 lbs. To get to calories it is 2.25 lbs X 453.59 grams per pound = 1020.58 grams X 4 calories per gram for protein = 4082.31 calories.

I think that is correct but I might have made a mistake as I am pretty fried at work today.

Dude. You know how to get the MEAT on.

Nice.

FitDay calculates it at 2559calories, 163grams fat, 0 carb and 254 g of protein. Who's right?

I have no idea. I was using the 4 calories per gram standard measure for protein. As I posted earlier I am pretty fried today that is why I did the math long hand with my work so others could see if I made a mistake. I started to say that maybe the reason was I was counting the meat entirely as protein, but that doesn't work because fat is 9 calories per gram and it would actually drive the entire caloric count up.

I must have made a mistake in my conversion or calculation somewhere. I did a quick google search and here is what I found.

“According to the USDA, one pound of ground lean beef has 1197.5 calories"

That jives with the number off of fitday. I also found this table that is calories / fat per 100 grams.

Brisket (boiled) 330 24g
Fillet Steak (grilled) 210 20g
Forerib (roast) 358 30g
Minced (stewed) 235 16g
Rump Steak (grilled) 220 13g
Rump Steak (fried) 250 15g
Silverside (boiled) 240 14g
Sirloin (roast) 280 20g
Stewing Steak 225 12g
Topside (roast) 219 11g

I don't know calories but I am confident to say that usually I am pretty tired of whatever roasted flesh I have been eating by the end of the day.:D

Water.

Some percentage of meat is water, it's not 100% protein and fat.
