Guest guest Posted July 10, 2003 Report Share Posted July 10, 2003 The variation is due to the difference in activity levels that might affect your life with those who are more active tending toward the higher end of the scale. Lean body mass confuses a lot of people too. Most people have a " percent of body fat " number that ranges above 20-25% with a average for the USA of around 40%. If a 140 lb woman has 30% body fat, and she is moderately active, then her percent of body fat is 42 lbs. That gives her a lean body mass of 98 lbs. Assuming .7 for the amount of protein she ought to consume for her activity level, her suggested protein need would be 68.7 grams of protein. A bit high for most veggies but that's what the guideline suggests.

Guest guest Posted July 10, 2003 Report Share Posted July 10, 2003 According to the World Health Organization, minimum protein requirement should be 5% of calories. So in a 2,000 calorie diet, protein should account for at least 100 calories, or 25 grams. The USDA builds a satety net in their recommendation and say 10%, which is 200 calories, or 50 grams. If you are eating a well balanced vegetarian or vegan diet with enough calories, it is virtually impossible to not get enough protein. Here's how your numbers work out: My lean body mass is 135 lbs. At .5 grams per pound, I would need to eat 67.5 grams of protein, or 13.5% of calories. This is a tad high, but falls in the 10-15% range suggested by the World Heath Organization as optimal protein intake (big safety net -- most people do not require 15%). At .9 grams per pound, I would need 121.5 grams of protein, or 24.3% of calories from protein. That figure sounds like it came out of " The Zone, " and is way too high. --- dave <dave4sale wrote: > how much protein should one consume? i've read > anywhere from .5 gram > per lb of lean body mass to .9 that's pretty broad.

Guest guest Posted July 10, 2003 Report Share Posted July 10, 2003 While I don't argue with your numbers, .9 grams per pound is hardly what THE ZONE diet recommends for most people (which is more like .5 to .7). A .9 factor is ONLY for very athletic people. Please, Lori, you can dislike the zone diet without misrepresenting it. I weight 172. My percent of body fat is now 22%. My lean body mass is 134 lbs. My activity level is moderate, thus a .7 factor. That translates into 93.8 grams of protein. I usually consume 80-90 grams of protein per day, and I usually have to supplement to get that. When I began the zone diet, my percent of body fat was 38%. How great is that? Dave Veggie for 22 years. In THE ZONE for 1.5 years and still loving it.

Guest guest Posted July 11, 2003 Report Share Posted July 11, 2003 How did I misrepresent " The Zone " diet? Barry Sears' book calls for 30% protein, 30% fat, and 40% carbohydrates. That is exactly what his book (which I've read) states. I'm glad you lost weight. Since his diet is a typical calorie reduction diet (disguised as something else), I would be surprised if you didn't lose weight on it, at least in the beginning. But there is no actual scientific evidence for his 30/30/40 formula. I was completely unable to find even one independent scientific study that stated that this is the formula you need to lose weight and be healthy. > While I don't argue with your numbers, .9 grams per > pound is hardly what THE > ZONE diet recommends for most people (which is more > like .5 to .7).

Guest guest Posted July 11, 2003 Report Share Posted July 11, 2003 Lori, As a veggie, I refer to " The Soy Zone " first published in 2000. I never read any of the earlier books. " The zone " books have been around much longer than three years and contains info which his later books updated and maybe corrected. You misrepresent " the zone " in several ways. 1. You said on July 10th, >>At .9 grams per pound, I would need 121.5 grams of protein, or 24.3% of calories from protein. That figure sounds like it came out of " The Zone, " and is way too high.<< This is only a small part of what the zone recommends about protein consumption, and in isolation, it presents a slanted view of what the zone is all about. Clearly, you do not like for the zone, and your statement about it is only true in a very limited if not confusing sense. 2. I offered a response correcting your original email, which is shown below, and you simply ignored it to make a new point about the zone. I'm not sure why you bring it up, whether it is accurate or not, b/c it was not in your original email. With this new email, I'm not sure if you're more concerned about " calorie consumption " or " protein consumption, " since you've commented on both in less than flattering ways. 3. In referring to the zone as a >>...typical calorie reduction diet (disguised as something else)...<<, you simply state an opinion, and you're certainly entitled to do that. It's my opinion that you've drawn conclusions that seem reasonable to you, yet fail to accurately communicate the underlying value (and I believe benefits) of the zone. Further, such opinions stated as authority diminish the value of what it's author has spent two decades developing, i.e., original findings that rely on varied scientific/medical research that has repeatedly been cited in professional journals. So, I suggest that there is FAR more to be gained from " the zone " that you imply. Dave Lori [mrsshf] Friday, July 11, 2003 7:29 AM RE: Anti-tein How did I misrepresent " The Zone " diet?

Guest guest Posted July 11, 2003 Report Share Posted July 11, 2003 Cite independant research studies (not studies performed by Sears, himself) that backs up Barry Sears' claims, please, because I have been unable to find any. For that matter, please find any study performed by Sears that has appeared in any legitimate medical journal. >Further, such opinions stated as authority diminish >the value of what it's author has spent two decades >developing, i.e., original findings that rely on >varied scientific/medical research that has >repeatedly been cited in professional journals.

Guest guest Posted July 11, 2003 Report Share Posted July 11, 2003 I don't understand this! Why do you disrespect Dr. Sears so much as to not even accept his own citations? Boy, you must really hate " The Zone. " I have read two zone books, and practically every paragraph involving scientific/medical/nutritional claims offered by Dr. Sears in " The Soy Zone " and " The Age-Free Zone " has a citation from a publication or professional journal, like JAMA, N Engl J Med, Brit Med J, and Am J Clin Nutr to name only a few. " The Soy Zone " references (pp. 306-24) and " The Age-Free Zone " references (pp. 343-99) are voluminous. I'll not repeat them here for obvious reasons. However, there are 74 pages of citations (over 1,000 of them) connected to practically every word that Dr. Sears asks his readers to believe. If only you had presented that kind of supporting info for what you offered to this group. I don't understand where you're taking this discussion.

Guest guest Posted July 12, 2003 Report Share Posted July 12, 2003 I have not read " The Soy Zone " yet, and I will pick it up at the library and read it and check citations for my own edification only, since I'm not going to bore the group with any further continuation of this discussion. I'm not a fan of " The Zone " or " Atlkins " or any other " high-protein " diet, because touting high protein requirements contributes to the lies the meat and dairy industries have been telling us for years. In addition, since a typical day on the original Zone diet involves eating 70% of protein calories from animal sources, Sears' diet contributes to the suffering and death of animals, which, since I'm a strict vegetarian for mostly ethical reasons, I could never condone. That's my feelings on the matter, and I can see that you have your beliefs that are completely different than mine. And that's okay. Live and let live and all that. --- daveo <daveo wrote: > Boy, you must really hate " The Zone. " > SBC DSL - Now only $29.95 per month! http://sbc.
