In contrast to chronological aging, biological aging or metabolic aging is a relative age of cells and tissues and the damage they've accumulated over years. Comparison of one's basal metabolic rate (BMR) to the average BMR of one's chronological age group gives the Metabolic age. Higher metabolic age of younger population is a serious concern and a key factor that leads to metabolic disorders in all age groups. Slower metabolism is a symbol of older age. Higher metabolic age indicates poor metabolism and higher risk of getting diseases and health complications later in life. Therefore, aging faster metabolically can severely impact chronological age. People with obesity and diabetes suffered the most due to current ongoing Covid-19 pandemic. Data suggest that SARS-CoV-2 patients with concomitant metabolic diseases had higher risk of worse prognosis and mortality. Lowering metabolic age can thus reduce the risk of getting age related health conditions and mitigate morbidities caused by pandemic like Covid-19. Therefore, maintaining healthy metabolic age in all age groups is required in the current unprecedented times. The aim of the review is to raise the prime concerns and to improve the population health outcomes by reducing the metabolic age.
