Low carb high protein -- a misnomer?
My understanding is that the liver only makes carbs as needed. I'm not sure
what happens to extra protein in this context. IMHO: Low Carb should be high fat, not high protein. "Ignoramus26161" wrote in message ... Here's what I am thinking about... If we eat more protein than our body requires for repairing body tissues, the rest is converted to carbs/glucose. If so, then a high protein diet actually supplies us with a lot of carbs, right? So, then, real low carbing should involve eating modest amount of protein, and not a gross excess of protein. Otherwise it is not really low carb. Makes sense? i |

In my mind, a LC WOE means that carbs are controlled and held low enough to curb appetite. Given that, a LC WOE could be high protein or high fat, with the other being mustly moderate. Most of us here practice a high fat version of LC as this version is geared for the non athlete looking to lose body fat (speaking of weight loss and thinking primarily in terms of Atkins). However, a high protein version of LC might be useful for those who do lots of exercise, due to the 58% conversion rate, which could then supply glucose to muscle tissue (I'm making this up as I go, but I'm also just spilling what's in my noodle).

Not exactly.
First of all, most of us are not eating that much more protein than before. Here's an example: I went to lunch with friends yesterday. We all ordered the same thing, a cheeseburger plate. I asked for no bun and had a salad instead of the fries. Since we all had the same hamburger patty... our protein content was the same... mine was a higher "percentage" of my meal, but the grams were the same as my friends. Also, protein does not convert to glucose the way you assume. Of every 100 grams (3 1/2 ounces by weight) of protein you eat, about 58 grams of it becomes sugar. But it's important to note that we are talking about the weight of the protein itself, not the weight of the protein food. A 3 1/2-ounce piece of meat weighs 100 grams, but it only contains about 20 or 25 grams of protein. The piece of meat would give about 10 to 14 grams of actual carbohydrates, not 58 grams. And only 58% of that 10 to 14g will convert to glucose, or about 6 - 8g of carbs. Jennifer Ignoramus26161 wrote: Here's what I am thinking about...

Ignoramus26161 writes: Suppose that I do eat an excess of protein, say 300 grams of it. Say that I use 100 grams for maintaining my body tissues, that leaves me with 200*0.58 == 116 grams of sugar produced. Other way around. 300 * 0.58 = 174g sugar, leaving you 126g protein to maintain body tissues. However, your liver stops converting protein when it has enough carbs, likely leaving more protein for body tissues. Since the liver stops converting when it has enough, I don't think overdoing the protein can have the same effects as overdoing the carbs, so IMHO it won't make it not LC. |

To eat 200g of protein you'd be eating approx. 800g - 1000g of actual food... remember it's not the weight of the food, it's the grams of protein in that food. Every 100g of a protein food is comprised of approx. 20 -25g of protein. And of course, yes it's possible to eat that much. Jennifer |
