Adherence
Exercise (particularly weight-bearing and muscle-loading) and higher protein intake can attenuate, but not prevent, the decline in bone mass associated with caloric restriction.
To protect your bones while dieting, prioritize resistance training and ensure you are eating enough protein. These strategies have been shown to reduce bone loss during weight loss, even if they don't stop it completely.
GoodQualifiesHIGH confidence
The first of these is exercise, and particularly weight-bearing and muscle-loading exercise, which mitigates the increase in bone resorption and decline in BMD when added to caloric restriction... higher protein intake have attenuated declines in BMD during caloric restriction.
Why this rating
Based on cited RCTs in older adults.

More from this paper
- Caloric restriction-induced weight loss in nonobese younger adults causes a significant decline in bone mineral density (BMD) at the spine and proximal femur, characterized by increased bone resorption and decreased bone formation.Good
- Mechanical unloading, changes in adipokines (increased adiponectin, decreased leptin), and reduced estrogen levels are primary mechanisms driving bone loss during caloric restriction.Good
