Youre also likely to lose bone mass.
Some studies have suggested that losing weight reduces bone mass, even when participants exercise.
Researchers from Spain published their findings in April 2025 inJAMA online grid Open.Lets break down what they uncovered.
How Was This Study Conducted?
This research team focused on 924 participants who underwent bone density scans.
These participants alsohad metabolic syndromeand were categorized as overweight or having obesity.
The participants were roughly split evenly between men and women, with all of them aged 55 to 75.
The 924 participants were randomly divided into two groups: a control group and an intervention group.
For the statistical analyses to be most accurate, it helps to have groups that are fairly even.
BMD means bone mineral density, or the concentration of minerals in a specific area of the bone.
What Did This Study Show?
Participants were followed for three years.
This study had a few limitations.
First, the study authors note that the results observed for the lumbar spine should be interpreted with caution.
This is because, as we age, calcium deposits can form, which may influence bone scan measurements.
How Does This Apply to Real Life?
About 54 million Americans have osteoporosis and low bone density.

The core includes your abdominal, back, diaphragm and pelvic floor muscles.
Specific exercises like planking, glute bridges and Kegels all target core muscles.
