 2. What you eat. Studies suggest that a plant-based diet with fewer animal products, more fruits, veggies, and whole foods is actually beneficial to aging and longevity, and of course, reducing things like refined sugars and the things that you know are bad for your health. And lastly, when you eat. When it comes to aging and longevity science, this is really a new area. Again, the majority of people will not be able to control their caloric intake, but research has shown that intermittent fasting can replicate some of the benefits of calorie restriction. If people can perhaps limit their eating to a brief window, it is believed that this can replicate many of the benefits that we are seeing in the calorie restriction studies.
