A nutrition PhD breaks down a comprehensive longevity study

While the goal is always to take in a normocaloric pattern of nutrients (i.e., for your calories to match your personalized metabolic needs), there are a few things to keep in mind. For example, when the amount of regular calorie intake exceeds the requirement, this can lead to a loss of energy balance.

When it comes to maintaining energy balance, I don’t have to say that our current food environment is working against us. Over the past few decades, we have experienced a major one-two-punch: portion sizes have increased dramatically, while the nutritional quality of our food has declined.

What’s more, we know from rats and primates Homo sapiens Saving yourself those calories not only helps one gain and maintain a healthy weight but more importantly, results in positive changes in body composition, such as less excess adiposity (fat mass) and more lean muscle tissue (fat-free mass).

Conversely, excess calories, fat storage, insulin resistance, and short lifespan are all intertwined. It’s not as fun as twisting. For example, we know that higher insulin levels are clearly associated with accelerated aging, a relationship that is preserved in many species.

Low calorie intake is directly related to the benefits of cardiometabolic health in terms of insulin sensitivity, heart physiology and even liver health. Furthermore, clinical studies indicate that calorie-saving biomarkers lead to improvements that indicate that “the pace of aging has been delayed.”

Has anyone else’s mind been blown away by the fact that we literally have the power to move ourselves for our well-being and the fulfillment of life? I personally find it very empowering.
