Medical Forum / General / Nutrition / July 2004Atkins & Exercise
I run about 40 miles a week or 1 hour a day 5 days a week. I limited my carbs to 125 grams a day for 2 weeks as a test. I was a friggen mess I had no energy and could not run at anywhere near more normal pace. Other than the aforementioned exercise I am basically sedentary sitting at a desk all day,driving a car, etc. I certianly don't expend anywhere near the energy of the average person from 100 years ago. However atkins makes it sound like this was the average diet or carb consumptions from that era. I think that is BS. The problem is not with carb consumption but lack of exercise. The human body was not meant to be sitting at a desk or lying on the couch all day. My 2 cents... It's been a while but you need to read Protein Power and Neanderthin. Both low carb books. Protein Power in particular discusses what you are talking about. What man used to do is short bursts of high energy, then lay around all day. Running for one hour every day is not what the normal man would do. Why would he? Sure he'd run from a lion, but that wouldn't require an hour of running. Nor would he run after game for an hour straight without stopping. So what you are doing is what is unusual for a human being. >It's been a while but you need to read Protein Power and Neanderthin.

Total energy expenditure I would think is what counts. However whether the caveman exercised other than a lot of walking and occasional running is besides the point. We know that moderate levels of exercise is good for you. I get moderate amounts of exercise and I can not function on an atkins diet. Atkins diet is for sedentary people only. Exercise actually helps your body utilize and burn fat more readily than sedentary person among other benefits. No. It's not for sedentary people. It's for people who wish to lose weight. Are you trying to lose weight or eat healthier? If you are trying to eat healthier, then you need to read Neanderthin or Protein Power. I am not on Atkins. I am on a low carb plan that was started by World Class body builder George Turner in the 1950s, long before Atkins. > Other than the aforementioned exercise I am basically sedentary > sitting at a desk all day,driving a car, etc. I certianly don't > expend anywhere near the energy of the average person from 100 years > ago. My ancestors ( French Canadain Voyagers ) paddled their canoes from Quebec to British Columbia every year for the fur trade. During this 9 month journey they ate almost nothing but Pemmican ( fat and dehydrated meat - the ultimate low-carb meal bar). A 1/2 pound daily ration allowed a man to paddle and portage from sunup to sundown. Low carb diets have been shown in clinical trials to improve the performance of runners. See: "High-fat diets help athletes perform." ScienceNews Vol.149 No. 18 (May 4, 1996) 287. Ray Audette Author "NeanderThin" www.NeanderThin.com > dehydrated meat - the ultimate low-carb meal bar).

Dr. Chung would be pleased :) Mirek >> Other than the aforementioned exercise I am basically sedentary >> sitting at a desk all day,driving a car, etc. I certianly don't [quoted text clipped - 15 lines] >Author "NeanderThin" >www.NeanderThin.com Show me any world class runner or cyclist on a low carb diet. There are none. So I don't know how it would improve performance. > I run about 40 miles a week or 1 hour a day 5 days a week. I limited > my carbs to 125 grams a day for 2 weeks as a test.

Lack of glycogen makes anaerobic exercise difficult. Anyway, long distance running is basically an aerobic exercise, so you should be OK. But it is possible that you have learned your body to perform it as the anaerobic one. If you would like to cut your carbs (which you dont, you was just experimenting), I would suggest to slow-down your running for a while or replace it by walking and then slowly work it up back. There is some adaptation possible over time. Mirek |
