Is a Calorie Deficit Really the Best Way to Slow Aging

Are scientists studying and researching aging from the angle of quality over quantity when it comes to how the human body ages? For example, scientists have been studying caloric restriction (CR) in various animal models, excluding humans yet, that shows promising efficacy with increasing longevity for many decades. However, what about testing a calorie surplus and/or maintenance with various types of diet protocols that takes into account higher-quality nutrient dense foods and if this would be a more effective optimal way to reduce aging than caloric restriction? Let’s explore this, because this hasn’t been studied well, and many observational studies are flawed with food, ingredients, and meals not appropriately programmed and formulated. In terms of providing stronger evidence, randomized controlled trials (RCTs) and experimental studies are generally considered to be better than observational studies because they allow researchers to establish a causal relationship between variables by randomly assigning participants to different treatment groups, which is not possible in observational studies where researchers only observe existing conditions.
