There's no question that nutritious eating and proper portions can be the keys to better overall health and therefore better aging, but as examined by Scientific American, recent studies delve more into how portion control and calorie restriction affect aging and have come across some surprising findings.
A study led by gerontologist Valter Longo at the University of Southern California and published in Science Translational Medicine suggests that anti-aging benefits can be gained without a tremendous reduction in calorie intake. A diet that mimicked fasting adopted for just five days a month for three months and then repeated as needed was found to be a safe and effective technique to reduce risk factors for aging and for diseases related to the aging process.
While much more research is required before anyone uses these findings to make drastic changes to their diet, it is clear that practicing portion control and avoiding overeating are both on track for better aging. Though scientists and nutritionists alike would dissuade individuals from counting every calorie, being aware of the intake you need to live a healthy, energized life can help with overall well-being and eventual longevity.
