• Astaxanthin may boost muscle endurance and fat loss - Nutra USA, 2/5/08 - "astaxanthin supplementation "accelerated the decrease of body fat accumulation with exercise training" - [Abstract] - Note:  Astaxanthin is just one of over 600 carotenoids.  The problem with taking large doses of just one carotenoid is that it may cause a deficiency of the others.  I had a study on that but the link went dead.  I tried to find it via http://www.archive.org/web/web.php but it was a .asp web page and it appears that it doesn't work with those extensions.

In additional experiment, we found that astaxanthin treatment accelerated the decrease of body fat accumulation with exercise training"

"The mean difference in leukocyte telomere length between the most active [who performed an average of 199 minutes of physical activity per week] and least active [16 minutes of physical activity per week] subjects was 200 nucleotides, which means that the most active subjects had telomeres the same length as sedentary individuals up to 10 years younger, on average."" - I'm must be in fat city on this one.  I must have averaged 60 minutes per day since I've been 18 which comes to 420 minutes per week.  Maybe that's the main reason people claim I look young. Plus I've always taken vitamin D which helps with telomere length also. - Ben

• How much physical activity is enough to prevent unhealthy weight gain? - Obes Rev 2003 May;4(2):101-14 - "The following consensus statement was accepted unanimously. 'The current physical activity guideline for adults of 30 minutes of moderate intensity activity daily, preferably all days of the week, is of importance for limiting health risks for a number of chronic diseases including coronary heart disease and diabetes. However for preventing weight gain or regain this guideline is likely to be insufficient for many individuals in the current environment. There is compelling evidence that prevention of weight regain in formerly obese individuals requires 60-90 minutes of moderate intensity activity or lesser amounts of vigorous intensity activity. Although definitive data are lacking, it seems likely that moderate intensity activity of approximately 45 to 60 minutes per day, or 1.7 PAL (Physical Activity Level) is required to prevent the transition to overweight or obesity. For children, even more activity time is recommended. A good approach for many individuals to obtain the recommended level of physical activity is to reduce sedentary behaviour by incorporating more incidental and leisure-time activity into the daily routine"

• Exercise Training, Without Weight Loss, Increases Insulin Sensitivity and Postheparin Plasma Lipase Activity in Previously Sedentary Adults - Medscape, 3/19/03 - "Exercise, without weight loss, increases SI [insulin sensitivity] and PHPL activity in previously sedentary adults, without changing K2 or fasting lipid levels. Furthermore, increased LPL is associated with a decreased total:HDL ratio, and an increased LPL:HL ratio is associated with a decreased waist circumference. Therefore, even modest amounts of exercise in the absence of weight loss positively affect markers of glucose and fat metabolism in previously sedentary, middle-aged adults" - I threw this out because I didn't know that "decreased total:HDL ratio ... is associated with a decreased waist circumference".  This might be a long shot but that sounds like increasing insulin sensitivity via such methods as metformin and increasing HDL via supplements such as niacin might decrease pot bellies. - Ben

The study has a drawback, though, that all such studies face, which is what's called a "healthy patient bias." In this case, women who exercise often might be more apt to take care of themselves in other ways, so that a decrease in breast cancer later in life may not be due to the exercise itself, but rather some other associated factor. The researchers accounted for this by factoring in subjects such as smoking history and weight. "After adjusting for all these factors we're pretty confident that what we see is the effect of exercise,""
