Caveat emptor:
“The amount of physical activity necessary to produce health benefits cannot yet be identified with a high degree of precision”
DHHS guidelines 2008
“no randomized trials of physical activity and cancer rates have been conducted”

Claude Bouchard, Steven Blair, William Haskell 2nd edition 2012
page 353:
“The International Association for the Study of Obesity concluded that for adults, 45-60 minutes per day is required to prevent the transition to overweight or obesity and that prevention of weight regain in formerly obese individuals requires 60 to 90 minutes of moderate-intensity activity or smaller amounts of vigorous activity (Saris et. al) 2003.
Similar recommendations were made in Dietary Guidelines for Americans 2005 (US Department of Health and Human Services [DHHS} and US Department of Agriculture 2005).”
page 354:
“Global Recommendations on Physical Activity for Health, published by the World Health Organization (WHO) in 2010 shift primary focus away from losing weight and toward first meeting the weekly physical activity target.” 150 minutes per week of moderate-intensity”.
page 82:
“The Heritage Family Study showed that although the average increase VO2 max attributable to an endurance training program was 16%, some participants did not change at all, and others had an increase of 50%. The variability in response appears to have a strong genetic link.”
page 395:
“A similar pattern of variation in training responses was observed for:
1- HDL-C
2- Total Cholesterol levels
3- Submaximal exercise heart rate
4- Blood pressure changes
(Bouchard and Rankinen 2001)
page 404:
“endurance training-induced changes in risk factors do not correlate well with changes in cardiorespiratory fitness level. On the other hand... it is impossible to predict the effects of regular exercise on one risk factor by observing the training response of another risk factor. Thus far we have no indication that there are people who are non-responders across all markers of risk for diseases. These observations emphasize that even if a person cannot improve cardiorespiratory fitness with regular exercise, it is likely that he will achieve other significant health benefits from a physically active lifestyle.”
page 235:
“The evidence for a role of physical activity in preventing certain cancers comes primarily from epidemiologic studies. The findings from such studies are supported by plausible biologic mechanisms.”
page 241:
“The data are clearest in support of physical activity or fitness as a means of preventing colon and breast cancers.”
page 227:
“There is now strong epidemiological evidence that regular physical exercise can prevent or delay the onset of type 2 diabetes.”
