Weight gain is common as you age. However, based on research findings, middle-aged woman with a healthy weight can prevent weight gain with exercise one hour a day.
Very many studies to learn how to lose weight. However, bright researchers Min Lee, ScD, of Harvard Medical School in Boston, only a few studies which find out prevention of weight gain.
In this study, Lee and his team find out the amount of physical activity needed to prevent weight gain calorie intake without restriction.
Detailed studies
In a study published in the Journal of the American Medical Association, the researchers followed the development of more than 34,000 women who had participated in the Women’s Health Study. When the study began in 1992, the participants’ median age was 54.
The participants were asked to report phisic activity and body weight at the beginning of the study and in the 3rd, 6th, 8th, 10th, 12th, and 13th years of the study.
All the women ate a normal diet and is not recommended to reduce calorie intake. Researchers divided participants into three groups, depending on the level of activity:
* The first group of physical activity of about 150 minutes a week.
* The second group is active for more than 150 minutes a week but less than 420 minutes.
* The third group is most active in moderate intensity physical activity 420 minutes or more a week, or about one hour a day.
Findings
In general, the light of Lee, the participants of the three groups experienced weight gain over time, an average of 2.35 pounds. But, the more active woman, the less weight gain.
“Compared to women in the most active groups, women from the other two groups experienced more weight gain,” explained Lee, was quoted as saying the site webmd.com, Tuesday edition (23 / 3).
Compared with the most active women, two groups are less active at greater risk of experiencing weight gain as much as 2.5 kilograms in three-year intervals. The second most active groups at risk of 7 percent more have adding 2.5 kg, and the groups most at risk off 11 percent larger.
However, the light of Lee, the relationship between physical activity and weight control only applies to those with normal weight, not on women who are overweight or obese women.
