> The only proven way to live longer and reduce your risk of essentially every disease is to reduce caloric intake.
The problem with this is how a continuous caloric deficit affects your quality of life. Your body tends to adapt by making you feel tired and killing your libido. Not to mention that being underweight becomes a health hazard past a certain age.
IMO, if you aren't overweight, eating a healthy diet and enough calories to maintain your weight will give you the best combination of longevity and durability.
