Strong Support

In middle-aged and older women, a 13-week program of diet and exercise that reduces body weight and fat mass does not change bone density in the spine or whole body, even though men experience similar weight and fat loss, suggesting that bone responses to these lifestyle changes differ between sexes.

Effects of a Combined Dietary and Physical Activity Intervention on Bone Density, Lean Mass and Fat Mass in Adults: The GOTO Trial

Cohort Study
Human
2026 Apr

In this study, both men and women lost weight and fat, but only the men’s bones got stronger. Women’s bones stayed about the same, suggesting that men and women’s bodies respond differently to diet and exercise when it comes to bone health.

In healthy men aged middle-aged and older, a combination of moderate calorie reduction and increased physical activity over 13 weeks is linked to small increases in bone density in the spine and whole body, even though some muscle mass is lost and body fat decreases.
