What is your protein grams per day target?
I make things complicated; it entertains me, I guess.
This aurthor (like many other informed sources), says that normal people need 0.8 g/kg body mass per day. The author further suggests 1.0 to 1.2 g/kg for endurance athletes. Am I an endurance athlete? No, but I figure the traumas of surgery, rapid weight loss, and strength training plus significantly increased cardio (though not high in the abstract) add up to needing more than the standard RDA.
I'd be tempted to use 1.0g/kg. But there is also the fact that studies suggest RNY patients don't absorb as much as 20% of our protein. So I use the upper end of that range, 1.2g/kg, as my target.
Of course, the "body weight" figure is based on a normal body composition. Having lots of fat doesn't change your protein needs much. So one approach would be to use your idea body weight instead of your actual body weight. That's probably close enough, but I prefer to calculate based on my current lean body mass, which may be higher than it will be when/if I reach an "ideal weight." I want to "feed" all my muscle I have now, not just the part I hope to keep.
Using my body fat scale, for example, my last weight of 274 at 35% body fat means I have an LBM of 178 pounds. I then multiply that my 1.235 (which estimates what I would weight with an LBM of 178 at 19% body fat) which gets me to 219.9 pounds. I multiply that by .454 to convert to kilograms, and then multiply that by 1.2g/kg. So right now my goal is about 120 g per day of protein.
A spreadsheet that tracks my weight loss automatically does the calculations for me, so all I have to do is type in my weight and body fat % each week.
My nutritionist told me that my protein requirements are 1.5g protein per kilogram of ideal body weight (which is based on height). She said at 6' 3.5" my protein requirement is 136g per day.
I am interested to know where other people got their protein requirements. The number my nutritionist gave me seems high. I have never been a fan of the "ideal body weight" calculation, based solely on height.

well, i agree with paul, you can't get it in in one shot. you can only process about or maybe 50 grams of protein at a time so you have to spread it out. i make a chocolate shake with designer whey twice a day and then try to get the rest through meat or other form of high protein. it's not easy becasue it's a lot of protein to get down. plus the shakes are gassy. they upset my pouch but i have no choice. so try to use a combo and get it in throughout the day...carbonblob
