Too much protein in one meal ups insulin?
Hi There,
I'm reading around and on lowcarbfriends, someone mentioned that a intake more then 42 grms of protein (in one meal) will spike insulin? I'm looking around and finding mixed messages.... Also , I wanted to buy some protein powder, I usually buy whey powder, but now I'm being told that it also may create an insulin spike despite being low carb. Is this something I should be concerned about? Is egg protein powder better for lowcarbing? Thanks kindly |

However, a 50 gram dose of protein powder makes me feel lethargic for a short time very much like the crash from a sugar surge. I find that 25 gram doses of protein powder have no subjective effect. An insulin response to protein might be a good wild guess. |

Excess protein creates excess glucose. But what's excess for one person may not be excess for another. Fat burned releases about 10% of its energy as glucose. The daily need for fat for building cell membranes and nerves and so on is a few grams of polyunsaturates. The excess dietary fat tends to get stored rather than burned. Protein burned releases about 50% of its energy as glucose. The daily need for protein is lower than most Americans eat and definitely higher than daily fat needs. The excess dietary protein tends to get burned rather than stored. These issues combine to explain why when you do the arithmatic low carb plans tend to be high fat not high protein. There's also the issue that calorie for calorie fat and protein are roughly as filling. Calorie for calorie many think fat does a better job of keeping hunger from coming back. Calorie for calorie fat tends to trigger more glucagon release and thus better loss. Does this mean using protin powder is a bad idea? Not really. It means it's less effective than other methods but it is easy and it does work. But it is very easy to eat enough protein to get an excess and the excess ends up 50% glucose by calories. |

No, someone misunderstands the insulin index of foods. *Protein causes more insulin release than carbs do, with fish causing the highest amount, but not in a spike the way carbs do, but rather over a longer, more prolonged period, which is why it won't spike blood glucose or insulin. About 58%of the protein you eat is converted to glucose, too, hence the wisdom of hormonally neutral fat in your diet to a generous degree. Susan Thanks for all the replies.....Susan ...the author of the post claims she got the information off: "The International Academy of Physique Conditioning (IAPC) states this in their book" So I don't know.....I don't know who they are...if reputable or not. (or perhaps she misunderstood what she was reading) But thanks |

I agree with your comments about fat, but *protein is converted to glucose ONLY IF THE BODY NEEDS IT. *Here is a quote from "Diabetes Solution" by Bernstein, M.D. It's interesting how you define need in your quote below. "Protein foods are only about 20 percent protein by weight (6 grams per ounce", the rest being fat, water, or undigestible "gristle." *The liver, instructed by the hormone glucagon, can ...very slowly... transform as much as 52 percent of the above 6 grams per ounce into glucose IF BLOOD SUGAR DESCENDS TOO LOW OR THE BODY'S OTHER AMINO ACID NEEDS HAVE BEEN MET." You clearly do not understand the meaning of the word "OR" in your quote above. 1) The body will convert protein to glucose if blood sugar goes too low. This happens independent of the body's amino acid needs for protein building and as such it is a metabolic starvation response - The body burns lean faster than it burns fat because in a famine the people whose metabolism drops as fast as possible are the ones still alive next year when the harvest happens. 2) The body will convert protein to glucose when the needs for amino acids for protein building have been met. This is independent of blood sugar level and as such is a metabolic response to *excess* protein calories. In other words, excess protein is converted to glucose, just like posters have written. The word "excess" matters, just like the word "OR" matters in your quote. |

I have posted this quote several times in this group and have never been challenged before. Which made me wonder if anybody even read my message. Dr. Bernstein was explaining that "you can quite easily survive on a diet in which you would eat no carbohydrate." And he went on to point out that the two dietary sources of blood sugar are carbohydrates and protein, and you can meet your carbohydrate needs by eating protein (and fats) only; leading to the quote above. Thanks again for you edifying comments. |

Thank you, Doug, for your astute comments and I agree with you. I have posted this quote several times in this group and have never been challenged before. Which made me wonder if anybody even read my message. The question becomes how much carb, protein or fat is just barely enough and when does it start to be excess. It's not an easy question to answer because if you take the essential amount of dietary carbs (zero), dietary polyunsaturated fatty acids (ten of grams), dietary protein (tens of grams) the total isn't enough total calories for the day. So metabolic excess isn't caloric excess. Not a simple system because of that. Dr. Bernstein was explaining that "you can quite easily survive on a diet in which you would eat no carbohydrate." And he went on to point out that the two dietary sources of blood sugar are carbohydrates and protein, and you can meet your carbohydrate needs by eating protein (and fats) only; leading to the quote above. Consider that carb, protein and fat each have different ways to handle and store excess grams. Carb - Can be synthesized so is not essential. Excess carbs can be stored as glycogen but the amount that can be stored is very limited. Low fat plans tend to keep the storage maxed out; low carb plans tend to keep the storage minned out close to zero. Excess is converted to saturated fat for storage in a process that's metabolically inefficient - This is the metabolic edge of low fat plans. When carb stores are near zero the cravings for carb disappear - This is the appetite suppresion edge of low carb plans. Carbs are burned at near 100% efficiency. Dietary carbs may not be essential but the optimal intake level is not zero - If it were every low carb book would tell us to do that. Protein - Certain amino acids can not be synthesized so protein is essential. Excess protein might have some tiny amount of storage potential but any such amount is small even compared to glycogen storage. Daily needs for protein are in the range of tens of grams and that includes growth of muscle as well as cellular rebuilding. Excess is converted to glucose at near 58% efficiency - This is one of the two sources of blood sugar in people fasting or eating zero carb diets. Nearly all Americans eat more protein than is needed. Fat - Certain polyunsaturated amino acids can not be synthesized so fat is essential. The body can store nearly unlimited fat. Daily needs for polyunsaturated fatty acids are the the range of tens of grams for cell membranes, nerves and cellular processes. The burning of fat for fuel is not tightly bound to dietary intake the way it is with carbs and protein. When fat is burned for fuel about 10% of the energy is in the form of glucose from the glycerol that binds the fatty acids. The fatty acids can be burned by converting them the acteyl-CoA slowly for aerobic respiration and/or by converting them to ketones quickly. Thus spilling ketones int he urine is a sign that fat is being burned quickly, not quite directly correlated with fat loss. The above addresses excess by type but not by total. Glucose in the blood is driven by type, though. |

Too much protein in one meal ups insulin?
"Tom G." wrote in It's almost useless to google for what is correct, because there are arguments for both. You would think that if it was all so cut and dry, that there would be no question as to what exactly happens and why it does so. Idon'tbelieve there's any absolute numbers in terms of calorie intake or percentages of food properties. Bottom line should be, how do you feel? A sedentary life style with a high carb diet produces Fat, Tired and very sluggish individuals! Since I got off my lazy fat ass in June at the age of 49 and started walking an hour a day and adopted a semi low carb diet(Avoiding junk foods), I've improved my energy level and dropped 18 pounds. I'm just eating real food and cut down on my bread consumption, I feel a lot more energetic these days and it's not that hard to accomplish or stay with this style of eating. |

Too much protein in one meal ups insulin?
Most doctors who I have consulted with have recommended whey-protein
shakes on a daily basis. My doctor has me using two scoops of powder in my morning smoothie, which comes to 50g of Protein. I actually supplement this with another half scoop of egg-white protein. The one thing that I try to pay attention to is the quality of the Whey Protein. Look for 100% organic Whey Isolate that is not sweetened with sugar alcohols or splenda. (personal choice) Of the options available to me at my local grocery store I like Jay Robb brand products. They are natural and only sweetiened with Stevia (a natural calorie free sweetner that doesn't cause gas and other digestive distress that some artificial sweetners can produce) On 2008-08-01 22:49:04 -0500, "Liam T." said: Hi There, I'm reading around and on lowcarbfriends, someone mentioned that a intake more then 42 grms of protein (in one meal) will spike insulin?
