It is extremely disengenous to downplay the risks associated with being overweight. While the BMI is completely absurd, the notion that health is correlated to weight is well established, even if the BMI's concept of measureing and placing a value on weight is absurd. As your weight increases your chances of developing cancer increase, and being overweight is the leading cause of the formation of Type II diabetes. Please do not suggest that being overweight is healthy, it is not, nor is drinking one glass of wine nor is a few chocalates a day (beacuse they have anti-oxidants!) The negative effects of the alchohol (a strong carcinogen) and extra calories of the chocalate far outweigh the benefits of thier alleged blood thining and anti-oxidant properties. There are a thousand more studies which do correlate increased weight with negative health effects, the most stunning and obvious of which are the research done in caloric restriction.
Caloric restriction diets (sometimes refierred to as CRON or CR) constitute consuming at or above the RDA of all the vital nutrients, but BELOW the RDA of caloric intake. Restrictions as small as 5% - 10% can cut your chances of developing cancer in half, and delay the onset of cancers, and slow the progression of existing cancers. Restrictions up to 40% are seemingly possible and can double your life expectancy. For all intents and purposes they slow your rate of physiological aging. CR diets are the only known mechanism which can actually extend the maximum life expectancy of organisms. It has been tested on everything from water flees to chimpanzees and has shown the same drastic health benefits and life extending properties.
Caloric Restriction with Optimal Nutrition: An Introduction
I have a good friend who is a Hospice nurse, of some 20 or 30 patients she has, only one does not have cancer, and that is a patient who is dying from aneorexia. While anorexia is certainly not CRON, it demonstrates that cancerous cells, the most energy intensive ones in the body, dont do well when there is not much extra energy to be had.
Being overweight, especially severely overweight, is one of the most under-recognized health hazards, specifically relating to its relationship with cancer. I would add that drinking alchohol is probably the most underated health hazard, again specifically relating to cancer. Take a look at the HERP index sometime and look where pesticides and 'man made' carcinogens compare with coffee, beer, or vodka.
