Tuesday, November 13th, 2007

small size LDL has bad health effect compared to large size LDL. small LDL seems to trigger the process of atherosclerosis more compared to large LDL. HDL also comes in various sizes and large HDL seems to do a very good job of hauling the cholesterol back to the liver. HDL also has very good anti oxidant effect.

large lipo proteins also may be a clue to longevity. a modest amount of exercise is best way to increase the size of LDL and HDL. transfat promotes smaller size LDL particles thus making transfat more dangerous for your health.

smaller LDL particles are also found in people who have insulin resistance syndrome. LDL particle size is also found to be inversely proportional to total triglycerides.

atherogenesis is the formation of lipid deposits in the arteries, smaller LDL particles and high TG – triglycerides are key factors in the  formation of plaque in the lining of the arteries

Saturday, September 15th, 2007

It is important to understand the difference between isometric and isotonic exercise. Using dumbbells for weight training is an example of isotonic exercise. There is joint movement and muscle contraction happening at the same time. Sometime the body is used as a resistance force.

In Isometric exercises the muscles may contract but there is not motion in affected joints. This is very useful for developing strengths of muscle groups. Yoga can be used as a part of any regular exercise regimen when done properly. Do not try complicated yoga poses without attention from yoga instructor.

One of the recent studies published in Archives of internal medicine suggests that there may be benefits and disadvantages to both the choices

The study found that in short term low carb dieters lost more than low fat dieters , but the differences were not as significant after first year.

Even though low carb diet increased the HDL (good cholesterol), it also increased the LDL (bad cholesterol).

Study also found that even though more people were able to stick with low carb diet, after about an year – it was difficult for people to continue their diets.

So is their a best way to loose weight ? It depends on your nature, if you have the tenacity to continue with regular regimen of healthy eating and exercise and enjoy the process then you may be able to loose weight and also tone your body.

Live longer and Stay healthy by washing dishes?

Wednesday, July 12th, 2006

A recent study by National Institute on Aging shows that active seniors are 70% likely to live longer. This should serve as an important reminder for Couch Potato lifestyles that some of the retirees of baby boomer generation may adopt.Drop that remote: try walking up to the TV to change the channels.

Instead of watching TV, walk to your car, take a walk in the park, work in your garden, even wash dishes, fold your laundry but do something with regular activity. Simple Yoga poses will be a great way to get started if you can handle them.

This again brings into light the value of exercise for healthy living.  Even if you fear the dreaded routine of exercises, just any reasonable activity is better than not activity at all. You can do some simple exercise, but at regular frequency.
Government now recommends a minimum of 30 minutes a day of moderate activity, such as brisk walking. However, the federal Centers for Disease Control and Prevention says that 1 in 3 men and 1 in 2 women over age 75 are not physically active at all.

The new study, published today in the Journal of the American Medical Association , did a complete study of 300 men and women and found that the least active group was three times as likely to die.

The researchers also found that an average older person, would burn the necessary calories to stay healthy by doing about hour to hour and half of household chores, or any other volunteer work that doesn’t involve just sitting in one location.

If you are younger or middle aged you need to do much more than that.

This study is important because it provides credible evidence that everyday simple activities may be beneficial.
