During weight-loss efforts involving substantially reduced food intake, maintaining bone health can become more challenging. Eating less can make it harder to obtain adequate protein, calcium, vitamin D, and other nutrients needed for bone maintenance. At the same time, losses in lean mass and reduced mechanical loading may work against healthy bone remodeling. These challenges may be greater during rapid weight loss and among people with additional risk factors such as older age, menopause, low baseline bone density, or nutritional deficiencies.
This concern is particularly relevant for people using glucagon-like peptide-1 (GLP-1)–based weight-management medications, who may consume smaller portions and fewer meals and may not consistently meet protein or micronutrient needs or follow resistance-training recommendations.
Existing knowledge around bone-supportive nutrients and protein intake provides an important foundation, but there is still room to improve how bone health is protected during rapid weight loss. Advances in nutrient delivery, mineral absorption, bone remodeling, and muscle-bone support could create new opportunities to preserve bone health and musculoskeletal resilience despite reduced food intake and smaller portion sizes.
We are looking for solutions that help preserve bone health and musculoskeletal resilience during rapid weight loss by supporting bone formation or healthy remodeling, reducing excessive bone resorption, improving use of bone-supporting nutrients, and preserving lean mass and function. Ingestible or formulation-based solutions should work in compact formats such as beverages, shots, gels, jellies, other spoonable or semi-solid products, snacks, bars, chews, powders, frozen products, or other formats offering a clear advantage for consumers with reduced appetite. Early-stage proposals are welcomed and should include initial supporting data, a testable hypothesis, key technical risks, a proof-of-concept plan, and, where relevant, a credible path to food or beverage use.
