Online Health Expert's Global, Online and Free "Move Movement" Updated to Include the Role of "Sirtuins" That Have Been Shown to Play a Pivotal Role in Regulation of Lifespan.


An excerpt from Online Health Expert Dr. Harish Malik's Global, Online and Free "Move Movement" showing the Role of "Sirtuins" and their connection with Calorie Restriction (CR) and Physical Activity (PA) that play a Pivotal Role in Anti-aging and have been shown to Promote Longevity.


Cutting calories/ Calorie Restriction (CR) and Physical Activity (PA) (CR has been shown to promote longevity) - promotes mobility (as the body retains the drive to do things after a lighter meal as opposed to a heavy meal) , moves lymph (which is 3 times the amount of total blood in our body and is dependent on body movement to keep it flowing - lymph is the policeman, garbage man and the immigration system of our body) better by negating the effects of gravity (Taller people are at greater risk of developing Cancer), and helps prevent/fight infections and cancer.

The Biochemical basis of Calorie Restriction (CR) and Physical Activity (PA) leading to its Anti-Aging effects has been recently linked to Sirtuins which have been shown to play a pivotal role in regulation of Lifespan. Dr. Franklin H. Epstein's (June 9, 2011) Lecture "Sirtuins, Aging, and Medicine" accessible at The New England Journal of Medicine details the role and pathways of Sirtuins in the pathways of aging. In an article "Role of Sirtuins, calorie restriction and physical activity in aging[Frontiers in Bioscience (Elite Edn.) Jan 01, 2012], a team of Italian researchers point out the clear-cut relationship between Sirt-1 and Calorie Restriction (CR) and in rats they showed that the levels of SIRT1 activity were raised in aged rats who performed moderately prolonged Physical Activity (PA). They found that in mammals, CR causes physiological and behavioral changes that lead to decreases in reactive oxygen species, thereby reducing oxidative stress and damage and thus leads to the hypothesis that CR by reducing oxidative stress extends lifespan by counteraction of aging.

Study Shows that Obesity Induced Brain Changes May be The Reason Why Weight Control is So Hard.


Online Health Expert Medical News Report: Weight Control in Obese Individuals Linked to Brain Changes due to Obesity.

Previously, an Australian study had shown that Rebound weight gain after dieting results from a homeostatic interplay of changes in weight regulating hormones.

Now, a new study reported in the Journal of Clinical Investigation Dr. Michael W. Schwartz, professor of medicine at the University of Washington are reporting how rodents and humans with diet-induced obesity have structural changes in their hypothalamus, an area in the brain, which controls body weight among many other functions. Body weight is regulated by a rather complex set of interactions between hormones and brain cells (neurons). There is a growing belief among researchers that these interactions, in most obese people, "conspire" to prevent long-term weight loss, and the underlying mechanisms are increasingly investigated by neuroendocrinologists.

Dr. Schwartz told the press:

"To explain a biologically elevated body weight 'set-point', investigators in the field have speculated about the existence of fundamental changes to brain neurocircuits that control energy balance. Our findings are the first to offer direct evidence of such a structural change, and they include evidence in humans as well as in mice and rats."

In a second study published in the same issue of the journal, another team of researchers, led by Dr. Jeffrey Flier, of  Harvard Medical School, Boston,  reported that turnover of nerve cells in the hypothalamus of mice is inhibited by obesity, adding further weight to the argument that physiology, rather than lapsing back to old eating habits, could be the reason for weight regain following a period of successful weight loss in obese people.

Virtual Exercise (Exergames like Wii Fit or PlayStation Move) May Improve Higher Mental (Brain) Functions Better Than Traditional Exercise in over 50 year old.


Online Health Expert News Report: According to the results of a 2 year study done on 101 volunteers 58 -99 years old, published in the American Journal of Preventive Medicine (January, 2012), Dr. Cay Anderson-Hanley, Assistant Professor at Union College, New York, found that Virtual reality enhanced interactive exercise (Cybercyclists)  yielded greater cognitive benefit and perhaps added greater protection (23% reduction in progression to MCI) against mild cognitive impairment (MCI) compared to traditional exercise.

Exercise could be linked to cognitive function via the increase in the blood levels of Brain-Derived Neurotrophic Growth Factor (BDNF).

Online Health Expert Medical News Flash: Analysis of 14 Studies Involving Children Between Ages of 6 and 18 Found Strong and Positive Relationship Between Physical Activity and Academic Performance.

Online Health Expert Medical News Report: A review of 14 studies published in the January, 2012  issue of Archives of Pediatrics & Adolescent Medicine involving children between Ages of six and eighteen found Strong and Positive Relationship between Physical Activity and Academic Performance.


The researchers noted that the increased oxygen and blood flow to the brain that accompanies exercise might be the reason behind their improved classroom performance.

Online Health Expert Medical News Flash: Consuming Excess Calories May Lead to Fat Gain Regardless of Source.

Online Health Expert Medical News Report: In a study published in the Jan. 4, 2012 issue of JAMA (Journal of American Medical Association), involving 25 healthy participants which were divided into 3 groups getting a low-protein, high-protein, and a normal-protein diet with equal calories (all of them received extra 1000 calories), the researchers found that the total calorie intake, regardless of the nutritional source of calories, determines the amount of fat accumulation in their bodies.  


These findings suggest that the current Obesity epidemic may be worse than is currently understood as those with lower body weight may have undetected layers of fat that can harm their health.
