Older women need more exercise to lose weight

Tuesday, May 18th, 2010

lose weightA new medical study says women need much exercise to lose weight as they age.

At least one hour of daily moderate activity is necessary for mature women a healthy weight and not on a diet. For those who are already overweight, that is, most Americans still need more exercise to avoid gaining weight without eating less, according to the results of the study.

“We must all work on it. If it were easy everyone would be thin as well,” said John Foreyt, an expert in behavioral medicine who reviewed the study but was not involved in its preparation.

A quick walk, bike or golf relaxing are examples of moderate exercise, but do not throw in the towel if you can not perform these activities at least an hour each day, for a little exercise is good for health, even and if not thinned to that practice, according to the researchers.

The study results were based on 34.079 women followed over 50 years for nearly 13 years. The majority were not on a diet to reduce calorie intake. During the study, women gained an average of about 2.72 kilos (six pounds). (more…)

Low testosterone associated with frailty in older

Wednesday, May 12th, 2010

Older men with low testosterone levels would be relatively more likely to become frail than those with normal hormone levels, according to a new study.

A study of more than 3,600 Australians aged 70 years found that those with low testosterone tend to become more fragile over the years.

The findings, published in the Journal of Clinical Endocrinology and Metabolism, add to evidence linking testosterone loss with health problems in older people. But it is not known what can be done.

“It is too early to recommend hormone therapy,” he told Reuters Health Zoe Hyde of the University of Western Australia in Perth.

“We need larger studies to see if testosterone can prevent or treat frailty and evaluate the benefits and risks of therapy,” he said.

Testosterone helps men to maintain bone density, muscle mass and strength, and the production of red blood cells.

Their levels naturally decline with age and previous studies have linked low levels in older men with diabetes, depression, broken bones and even a reduction in life expectancy. (more…)
