Individuals who lose weight on low calorie diets alone may be
susceptible to bone loss. The same is not seen when exercise is
included as part of an overall fat loss plan.
Most US adults are either overweight or obese. The most common
treamtent for these conditions is lifestyle changes, including exercise
and reducing overall caloric intake. Some, however, skip the exercise
and try to lose weight by dieting alone.
Decreasing body weight from dieting alone is associated with
decreased bone mineral density, which increases the risk for hip
fractures and osteoporosis in older adults. The same kind of bone loss
is seen in younger women who are anorexic or whose body weight is low
enough to stop menstruation.
These findings reinforce the importance of including exercise for
healthy weight loss especially if you are dieting. The two types of
exercise that provide the best bone enhancing stimulus are weight
bearing activities and weight lifting.
Weight bearing aerobic exercise should maximize impact to the
skeleton to improve bone mass in the hip and other areas where
fractures are common. If a person is of normal weight and have healthy
bones and joints they should perform some type of jumping activities in
addition to the more common low impact activities.
Weight lifting provides strong muscular contractions that transfer
force to the bones resulting in an increase in bone mass. Healthy
clients should maximize the amount they lift but stay within safe
limits that allow them to perform the exercise in good form. A weight
training program needs to work the entire body since the stimulus to
increase bone density only occurs near the body part being trained.
Low calorie diets are a popular means of trying to lose weight.
Dieting alone, however, may sacifice bone integrity. To avoid bone loss
and actually increase it, add weight bearing exercise or weight
training to your fat loss program. Watching your calories and
performing regular exercise will also result in better fat loss.
