Physical Activity does help Weight Loss significantly

Jan. 1, 2011 - PRLog -- The prevalence of overweight and obesity in the U. S. is still high. According to World Health Organization (WHO) statistics, countries with highest proportion of people being overweight include Samoa (93.5%), Kiribati (81.5%), French Polynesia (73.7%) and Saudi Arabia (72.5%). The U.S. ranked the sixth in being the highest with 66.9% of population overweight.

In regard to a more severe case, obesity, overall, 33.8% of adults were obese in the U.S. More females than males were obese (35.5% vs 32.3%). The highest frequency of females being obese occurred in the age group 40-59 (38.3%). For males, it was in the age group 60-100 (37.1%).

According to a study from the University of Pittsburgh on the efficacy of weight loss and physical activity intervention on the adverse health risks of severe obesity (The Journal of the American Medical Association, 2010; 304 (16): 1795-1802), lifestyle intervention consisting of diet and physical activity can significantly reduce the weight for the people with severe obesity with BMI between 35 and 39.9(BMI is calculated as weight in kilograms divided by height in meters squared. WHO defines obesity as BMI value equal to or greater than 30).

The study was based on the effect on weight loss for two groups of obese people for one year. One group was prescribed a diet with carefully planned macronutrient composition and a progressive physical activity program was also prescribed for the entire 12 months (Group 1). The other group had the same dietary intervention but with physical activity delayed for 6 months (Group 2).

The result shows that Group 1 lost significantly more weight in the first 6 months compared with Group 2. But weight loss at 12 months was similar in the two groups, indicating that physical activity does have effect on weight loss. It promotes greater weight loss and has the ability to sustain that weight loss.

Diet alone results in 2-3% less weight loss than what is achieved with the combination of diet plus physical activity.

Then how much difference is the result if  compared with those who were not instructed to do anything – without diet and physical activity intervention in the weight loss process? In another study on the effect of a free prepared meal and incentivized weight loss program on weight loss in obese and overweight women (The Journal of the American Medical Association, 2010; 304 (16): 1803-1810), participants were randomized into three groups. The two intervention groups were provided with prepackaged prepared foods with low calorie content and instructions for increased physical activity with 30 minutes on five or more days per week plus one-to-one counseling either in person or through telephone while the usual care group was provided with publicly available weight loss material only.

After two years, it was found that more than twice the proportion of participants in the intervention groups compared with the usual care group had a weight loss of 10% or more.

Thus free prepared meals and incentivized structural weight loss program that promotes diet and physical activity successfully facilitated weight loss and weight loss maintenance compared with a control group.

Actually, overweight and obesity are due to calorie intake being more than used in the body. As doing physical activity increases the body using the calories, it facilitates the effect of weight loss. In view of many side effects of taking medicine to reduce weight, the use of traditional way to cure the root cause of overweight and obesity is highly recommended.

“In most cases, obesity is caused by overeating - eating more than our body needs with the result that fat accumulates in the body. But sometimes due to metabolic disorders such as weakening of thyroid or adrenal gland, digestive metabolism is reduced. Complex sugars and glucose can be easily converted to fat instead of properly metabolized, then fat can be accumulated in the body and causes overweight and obesity,” Frank YS, director of http://www.LossWeightEbook.com said. In such case, using herbs can rebuild the tissue so that it can function properly again.
