Metabolic syndrome and Type 2 diabetes mellitus are the main 21st century pandemics that increase in prevalence worldwide. Cardiovascular disease as a leading cause of death among patients with metabolic syndrome, morbid obesity and Type 2 diabetes mellitus, includes a unique form of heart failure that is independent of most of the main coronary risk factors. General lipid excess associated with mitochondrial dysfunction, and accumulation of myocardial lipids with consequent aberrations of cardiac metabolism seems likely to play the main role in a problem referred to as Lipotoxic Cardiomyopathy.
A new Australian study reliesed online Jan 11 (2010) and soon to be published in Circulation, proved that living as a “couch potato” on a daily basis is quite detrimental for one’s longevity. The study collected data on the lifestyles of 8,800 healthy men and women aged 25 years and older. As a typical metabolic trial, in addition to lifestyle habits, the researchers tested participants' cholesterol and blood sugar levels. Over more than six years of follow-up, 284 people died (87 were due to cardiovascular disease and 125 from cancer).
The participants were grouped into three TV - watching categories: those who watched less than two hours a day; those who watched two to four hours a day; and those who watched more than four hours a day. Comparatively to people who watched less than two hours of television daily, those who watched more than four hours a day had a 46 percent higher risk of death from all causes and an 80 percent increased risk for CVD-related death. This association was hold regardless of other independent and common cardiovascular disease risk factors, including smoking, high blood pressure, elevated blood cholesterol, unhealthy diet, enlarged waits circumference, and leisure-time exercises.
The researchers found that each hour spent in front of the television daily was associated with:
1. 11 % increased risk of death from all causes,
2. 9 % increased risk of cancer death; and
3. 18 % increased risk of CVD-related death.
While the study was concentrated specifically on TV watching, the findings suggested that any prolonged sedentary behavior, such as sitting in front of a computer, or a desk may pose a risk to one's health. As David Dunstan Ph.D.said, ”The human body was designed to move, not to sit for extended periods of time. Technological, social, and economic changes mean that people don't move their muscles as much as they used to - consequently the levels of energy expenditure as people go about their lives continue to shrink. For many people, on a daily basis they simply shift from one chair to another - from the chair in the car to the chair in the office to the chair in front of the television."
Despite the study was done in Victoria (Australia) by the Physical Activity Laboratory at the Baker IDI Metabolism and Diabetes Institute it may be strongly implicated for the well known “American Couch Potato “life style of living also. Dunstan (the lead author of the study) stated, "The findings have serious implications for Americans and Australians when you consider that aside from sleeping, watching television is the behavior that occupies activity of four hours viewing a day, This research provides another clear link between too much sitting and death from a cardiovascular disease, cancer or mortality from all causes."
The strong correlation between obesity and a “couch potato” style of living can be easily predicted, but what the main conclusion of the above study is that even normal-weight or slightly overweight people can have blood sugar increase and dyslipidemiа problems (a decreased HDL and highly elevated LDL and triglycerides). Of course there are also few positive news coming from the above research, "that when moving muscles regularly throughout the day there are effective ways to manage normal weight and to protect against the CVD disease".
The association between TV watching and death remained unchanged even while other risk factors such as smoking, high blood pressure, elevated cholesterol, unhealthy diet, obesity were taken into consideration. "In other words, irrespective of how much exercise you do, if you sit watching television for four hours on a daily basis you still have a substantially increased risk of early death from all causes and a much greater risk of cardiovascular disease" Dunstan stated.

Even overdoing your exercise is not much of a help as per team statements. "What we are now starting to understand is that the risks associated with sedentary behavior are not necessarily offset by doing more exercise," the author said.
As final conclusion of the above study in order to stay healthy, we need to keep on the move and to exercise regularly, purposefully, consciously, and comprehensively.
