A Harvard study highlights key factors for healthy aging, focusing on genetics, diet, and lifestyle. Metabolic rate slows with age due to muscle loss and hormonal changes, making weight management challenging.
Longevity genes, like FOXO3 and KLOTHO, play a significant role in determining lifespan. FOXO3 regulates stress resistance and cellular repair, while KLOTHO modulates pathways related to aging.
Recent research suggests genetics may outweigh diet in determining longevity. Studies on mice showed that genetic differences significantly impacted lifespan, even with calorie restriction. However, a balanced diet and exercise still improve metabolic health.
Antioxidant-rich foods, such as berries, citrus fruits, and green leafy vegetables, help neutralize harmful free radicals. Anti-inflammatory foods like fatty fish, olive oil, and spices such as turmeric and ginger are also beneficial.
Regular exercise, including strength training, combats muscle loss and boosts metabolism. Adopting an active lifestyle and focusing on healthy eating are crucial for maintaining a healthy weight and quality of life after 50.
