For women over 40, bone health is a serous concern. According to the National Osteoporosis Foundation, 80 percent of the 10 million Americans who suffer from osteoporosis are female. Also, around half of all women over the age of 50 will break a bone due to osteoporosis at some point. It’s thought that bone loss is prevalent in older women due to a menopausal decrease in estrogen, which is known to protect bone health. Bone problems are so common that the chances of an older woman breaking her hip are equal to her risk of breast, ovarian and uterine cancer combined. It’s estimated that 1.5 million people, both men and women, suffer a fracture every year due to weak bones. The good news is that there are many steps that can be taken to promote bone health. The bad news is that older women who are also trying to lose weight could have a harder time preventing bone loss.
New Report Says Bone Loss Tied to Weight Loss
A new study appearing in the Journal of Clinical Endocrinology & Metabolism involved 424 people whose ages ranged from 30 to 70. Around 60 percent of the participants were women, and all of them were considered overweight or obese when the study began. The men and women were randomly assigned to one of four different low-calorie diets in order to lose weight. To test the link between weight loss and bone loss, researchers measured the bone density of each participant’s hip and spine over the two-year period of dieting. By the end of the study, the men and women had lost 8 percent and 6.4 percent of their original body weight, respectively.
Although the men and women both lost a similar amount of weight, their bone densities ended up reacting in completely different ways. The women experienced bone density loss at the hip and spine while men experienced no change an the hip and an actual increase in spine density. Menopausal women who primarily lost belly fat were particularly prone to losing bone density. Loss of lean muscle mass was also linked to a drop in bone density. While women only lost 1 to 2 percent of their bone density during the study, the results may nonetheless be a catalyst for future research.
Preventing Bone Loss
For young women, promoting bone health means getting plenty of exercise, eating a well-balanced diet high in calcium and vitamin D, and avoiding smoking and drinking. High-impact, weight-bearing activities such as running, tennis, climbing stairs, dancing and jumping rope can be very effective. Other exercises that promote muscle strengthening, balance and posture can also help prevent bone issues later in life.
For menopausal or post-menopausal women, bone loss can be treated by taking certain medications or estrogen under a doctor’s supervision. Women at this age can also benefit from getting enough calcium and vitamin D. The easiest ways to get these is to consume dairy products, get a bit of sunlight (not too much) and take supplements. It should be noted, however, that milk in particular has not always proven to be beneficial for bone health.
Bone Health and Weight Loss: The Bottom Line
If you’re a menopausal woman who’s trying to lose weight, you should take whatever steps are necessary to prevent bone loss while doing so. Simply moving part of your exercise routine outdoors, continuing to eat some dairy products, and taking vitamin D supplements may help avoid losing bone density while you’re busy shedding pounds of fat.
