7 Diet Changes Reverse Biological Age in Older Adults Within 4 Weeks¶
Researchers at the University of Sydney found that older adults aged 65–75 who shifted their diet toward lower fat and higher carbohydrates showed reduced biological age markers within four weeks. The omnivorous high-carbohydrate diet produced the strongest results, measured across 20 biomarkers including cholesterol, insulin, and inflammation markers.
- 104 participants aged 65–75
- Omnivorous high-carbohydrate diet showed strongest results
- Biological age assessed using 20 biomarkers
- Changes detected within four weeks
- Study preliminary; longer-term persistence and disease-risk reduction remain unknown
