A woman consuming 87% ultraprocessed calories showed significant intramuscular fat infiltration visible on MRI scans, indicating systemic muscle quality deterioration. Intramuscular fat weakens muscles by blocking fiber regeneration, increasing mechanical stress on joints—a major osteoarthritis risk factor increasingly affecting people under 55.

Consumers face increased healthcare costs, reduced quality of life, and potential disability from muscle weakness and joint disease. This may drive demand for healthier food alternatives and preventive health services, but increases out-of-pocket medical expenses for affected populations.
Governments may implement stricter regulations on ultra-processed food marketing (especially to children), sugar taxes, nutritional labeling requirements, and subsidies for whole foods. Healthcare systems may face increased treatment costs for osteoarthritis and related conditions, potentially driving preventive health policies.
