How do you define "physically fit?" The OP can do 70-mile rides at 16 mph while weighing 275 on hilly terrain. Are football players who run up and down the field not fit? ARe 300 lbs bodybuilders not physically fit? I do agree with you that there are many high BMI's people who are definitely NOT physically fit by any standards. I'm just saying that there are very real exceptions and applying blanket notions and numbers is not useful in light of MORE information. The BMI issue has been researched reasonably well. In general, higher BMI's are associated with higher rates of mortality across broad populations. As for "Are football players who run up and down the field not fit?" Yes, they are. But, does that mean they have a lower risk of disease/mortality? I kind of doubt that it does - I've read that pro football players tend to die quite a bit earlier than others. Clearly, there are exceptions, and more research needs to be done, but across large populations, in many studies, high BMI has been shown to be a risk factor. Do you have any cites that disprove the link between BMI/fatness and mortality in "physically fit" people with high BMI's? I would be most interested in any published studies you could cite. Here's an abstract from the New England Journal of Medicine (Volume 341:1097-1105 October 7, 1999 Number 15) that did a study of 1 million adults, comparing BMI to mortality and filtering for smoking status, age, and race. They found that the lowest risk of mortality was associated with BMI's of 23.5 to 24.9 in men and 22.0 to 23.4 in women. Body-Mass Index and Mortality in a Prospective Cohort of U.S. Adults Eugenia E. Calle, Ph.D., Michael J. Thun, M.D., Jennifer M. Petrelli, M.P.H., Carmen Rodriguez, M.D., M.P.H., and Clark W. Heath, M.D. ABSTRACT Background Body-mass index (the weight in kilograms divided by the square of the height in meters) is known to be associated with overall mortality. We investigated the effects of age, race, sex, smoking status, and history of disease on the relation between body-mass index and mortality. Methods In a prospective study of more than 1 million adults in the United States (457,785 men and 588,369 women), 201,622 deaths occurred during 14 years of follow-up. We examined the relation between body-mass index and the risk of death from all causes in four subgroups categorized according to smoking status and history of disease. In healthy people who had never smoked, we further examined whether the relation varied according to race, cause of death, or age. The relative risk was used to assess the relation between mortality and body-mass index. Results The association between body-mass index and the risk of death was substantially modified by smoking status and the presence of disease. In healthy people who had never smoked, the nadir of the curve for body-mass index and mortality was found at a body-mass index of 23.5 to 24.9 in men and 22.0 to 23.4 in women. Among subjects with the highest body-mass indexes, white men and women had a relative risk of death of 2.58 and 2.00, respectively, as compared with those with a body-mass index of 23.5 to 24.9. Black men and women with the highest body-mass indexes had much lower risks of death (1.35 and 1.21), which did not differ significantly from 1.00. A high body-mass index was most predictive of death from cardiovascular disease, especially in men (relative risk, 2.90; 95 percent confidence interval, 2.37 to 3.56). Heavier men and women in all age groups had an increased risk of death. Conclusions The risk of death from all causes, cardiovascular disease, cancer, or other diseases increases throughout the range of moderate and severe overweight for both men and women in all age groups. The risk associated with a high body-mass index is greater for whites than for blacks. GG http://www.WeightWare.com Your Weight and Health Diary |

He's eating too many calories, evidently. Good post...the law of thermodynamics has not (AFAIK) been repealed. Personally, I think low-cal works for some folks because protein and fats provide our bodies with stuff that tastes good and makes us feel "satisfied". I'm not an Atkins fan because I work out a lot and need enough carbs to train, but I have found more success with a "higher lean protein + veggies + good fats" approach than I did on a low-fat regimen. On low-fat I had more cravings and would often find myself hungry 2 hours after a meal. Plus, I would get sleepy in the afternoons more often. People are different and some folks can be successful on low-carb and others on low-fat. The trick is finding out what works for you. GG http://www.WeightWare.com Your Weight and Health Diary |

... I know I asked for some thoughts, but come on, people! 170 responses in 48hrs? Maybe I should have asked a less controversial question like the role of religion in politics or something. Or maybe you all should be spending more time on your bikes and less in front of the computer! Here are some generalized opinions culled from those replies and my response to them. 1. I don't realize how much I'm really eating - Maybe, but I've started keeping track again of everything that enters my mouth (I've done this before). In the last two days (two typical days to the best of my judgment) my caloric intake has not exceeded 2700. I'll keep tracking for a week or two to see if that changes, but I doubt it will. I just can't eat that much. Maybe I'm binging on the weekends. 2. I'm not burning as much as I think I am on my rides - Maybe, but my computer is correctly set, and I do wear a HRM. Every calculator I can find tells me I'm burning at least 6400 calories a week on my rides, and some estimate it as high as 10,000. I keep a ride dairy, so I know I'm not over estimating my miles. Remember, I weigh 274. 3. I have a diabetic condition that is preventing me from losing weight - This worried me. My family does have a history of Type II when they get old and fat, but I have had none of the symptoms. But I did get a HbA1c test. 4.7%. 7% is considered threshold level for some kind of diabetic disorder. So... after 170 posts (for which I'm grateful, don't get me wrong), I'm back to beginning. I guess I'll go see a medical pro. Get all the offiicial tests on the treadmill and all that. Who do I see? A sports physiologist? Thanks Doug - one possibility that I haven't seen mentioned in other posts... How much alcohol do you consume? Your description of a normal body except for a big gut sounds suspiciously like a "beer gut" (aka, an alcoholic's gut). If you're knocking back a 6-pack most evenings, that could account for your shape. GG |

I think the reasons pro football players die early is many reasons. 1) they quit being active but keep other bad habits (probably the most telling reason), 2) they get beat down during their careers, just for two. :: :: Clearly, there are exceptions, and more research needs to be done, :: but across large populations, in many studies, high BMI has been :: shown to be a risk factor. Do you have any cites that disprove the :: link between BMI/fatness and mortality in "physically fit" people :: with high BMI's? I would be most interested in any published :: studies you could cite. I'm currently reading (okay, about to read - i just got this today) the book "The Obesity Myth: Why America's Obsession with Weight is Hazardous to your Health" by Pal Campos. I'll let you know what I find out here. :: :: Here's an abstract from the New England Journal of Medicine (Volume :: 341:1097-1105 October 7, 1999 Number 15) that did a study of 1 :: million adults, comparing BMI to mortality and filtering for smoking :: status, age, and race. They found that the lowest risk of mortality :: was associated with BMI's of 23.5 to 24.9 in men and 22.0 to 23.4 in :: women. See -- this is one point that the author of that book makes. Look at the BMI of the lowest risk -- those are pretty high numbers for men -- heck, that's almost fat! So it certainly doesn't follow that lower BMI = longer life. :: :: :: Body-Mass Index and Mortality in a Prospective Cohort of U.S. Adults :: :: Eugenia E. Calle, Ph.D., Michael J. Thun, M.D., Jennifer M. Petrelli, :: M.P.H., Carmen Rodriguez, M.D., M.P.H., and Clark W. Heath, M.D. :: :: ABSTRACT :: :: Background Body-mass index (the weight in kilograms divided by the :: square of the height in meters) is known to be associated with :: overall mortality. We investigated the effects of age, race, sex, :: smoking status, and history of disease on the relation between :: body-mass index and mortality. :: :: Methods In a prospective study of more than 1 million adults in the :: United States (457,785 men and 588,369 women), 201,622 deaths :: occurred during 14 years of follow-up. We examined the relation :: between body-mass index and the risk of death from all causes in :: four subgroups categorized according to smoking status and history :: of disease. In healthy people who had never smoked, we further :: examined whether the relation varied according to race, cause of :: death, or age. The relative risk was used to assess the relation :: between mortality and body-mass index. :: :: Results The association between body-mass index and the risk of :: death was substantially modified by smoking status and the presence :: of disease. In healthy people who had never smoked, the nadir of the :: curve for body-mass index and mortality was found at a body-mass :: index of 23.5 to 24.9 in men and 22.0 to 23.4 in women. Among :: subjects with the highest body-mass indexes, white men and women had :: a relative risk of death of 2.58 and 2.00, respectively, as compared :: with those with a body-mass index of 23.5 to 24.9. Black men and :: women with the highest body-mass indexes had much lower risks of :: death (1.35 and 1.21), which did not differ significantly from 1.00. :: A high body-mass index was most predictive of death from :: cardiovascular disease, especially in men (relative risk, 2.90; 95 :: percent confidence interval, 2.37 to 3.56). Heavier men and women in :: all age groups had an increased risk of death. :: :: Conclusions The risk of death from all causes, cardiovascular :: disease, cancer, or other diseases increases throughout the range of :: moderate and severe overweight for both men and women in all age :: groups. The risk associated with a high body-mass index is greater :: for whites than for blacks. :: :: GG :: http://www.WeightWare.com :: Your Weight and Health Diary |
