Longevity Diet and the Fasting-mimicking Diet

The longevity diet generally consists of three isocaloric meals and one snack (for normal-weight individuals) or slightly hypocaloric meals (in the case of overweight or obesity). The diet consists of 50-60% of calories from complex carbohydrates, 30-35% of calories from mostly unsaturated fats, and 10-11% of calories from proteins, primarily from plant sources and fish, and occasionally from eggs, dairy, and meat, especially for those over 65. The diet is formulated to provide all necessary nutrients, including vitamins and minerals. The fasting-mimicking diet is a dietary intervention in which normal food is replaced with a standardized, highly hypocaloric vegan diet for a limited period of 5 consecutive days. This diet is designed to stimulate the same processes normally activated during fasting while minimizing the side effects of total food deprivation.
