What we put into our bodies is just as important as what we put on them. Oftentimes, the focus on topical skin care causes us to overlook the necessity of nourishing ourselves from within. With the proper balance of diet, lifestyle, and skin care, it is possible to increase longevity and achieve long-lasting health benefits that will make you look and feel your best. This blog will explore the connection between caloric restriction and longevity and delve into its impact on skin health and anti-aging. We will explore how reducing calorie intake may promote longevity by affecting cellular processes related to aging and discuss potential benefits for skin health, including a holistic approach to reduction in oxidative stress and skin inflammation. Additionally, we’ll explore how the science of topical skin care products at the heart of OneSkin’s product line can work in tandem with this lifestyle change to enhance the positive effects on longevity and skin health.

What is Caloric Restriction?

Caloric restriction is a dietary approach that involves thoughtfully reducing the amount of calories consumed at mealtime rather than limiting the window of time in which one eats (as in fasting). In the realm of health and longevity, caloric restriction emerges as a fascinating concept that, if done safely and properly, can boost health without compromising nutritional needs. The goal of caloric restriction is not exclusive to weight loss – in fact, it can help us to tap into our cellular processes which can extend health beyond just physical appearance.It is important to note that caloric restriction is not a one-size-fits-all approach; it varies based on factors such as age, sex, and individual metabolic rates. Generally, it involves consuming fewer calories than the typical intake, often by around 20-30%. This dietary adjustment necessitates careful consideration of nutrient density, ensuring that despite the caloric reduction, the body receives essential macronutrients and micronutrients, such as vitamins and minerals, which are vital components for optimal functioning. Later on, we’ll provide some tips on how to safely implement this method in your daily routine!

Health Benefits of Caloric Restriction

Caloric restriction offers a multitude of health benefits that extend far beyond the simple act of consuming fewer calories. When done safely, caloric restriction positively impacts cellular processes by influencing senescence
, oxidative stress, and inflammation.3
One of the remarkable caloric restriction benefits is the reduction in the number of senescent cells – cells that have reached the end of their life and are no longer functioning as they should and thus contribute to aging and age-related diseases. A buildup of these cells can induce chronic inflammation, immune suppression, and damage to neighboring cells. Some benefits of calorie restriction have been shown to promote autophagy, the body's natural recycling mechanism, enhancing the removal of damaged cellular components, fostering overall cellular health,1 and decreasing senescence in the long run.7
Moreover, caloric restriction has demonstrated a remarkable ability to lower oxidative stress, a primary driver of aging. By curbing the production of free radicals
and enhancing the body's antioxidant defenses, this dietary practice can help provide a shield against this stress on our cells.2 Simultaneously, inflammation, another accomplice in the aging process, is subdued under the influence of caloric restriction. Calorie restriction induces the production of anti-inflammatory rather than proinflammatory macrophages (cells that remove other diseased and damaged cells).3

How Does Caloric Restriction Impact Longevity?

Caloric restriction is an unexpected ally in the quest for longevity. The underlying mechanisms that contribute to longevity involve the enhancement of cellular resilience and overall health. Metabolic adaptations induced by caloric restriction are similar to the effects of other longevity-promoting interventions, such as intermittent fasting
. As the body adapts to a state of reduced caloric intake, it seems to activate survival mechanisms that transcend the immediate need for energy, leading to long-term benefits for health and longevity. According to a study of calorie restriction (CR) in humans, “while the rodent and primate data indicate that lifespan extension is possible with CR, collective analysis of the rodent data suggests that intensity and onset of CR required to induce these effects is probably not suitable for many individuals” but that “a reduced energy intake that is nutritionally sound improves age-associated health”.4 Additionally, in a recent neuroscience study by UT Southwestern, Dr. Takahashi explains that “experiments dating back to the 1930s have shown that decreasing typical calorie counts by about a third extends life span as well as health span – the length of time before diseases associated with old age arise – in every species in which this phenomenon has been studied”.5 In simple terms, when done properly, calorie reduction is able to promote increased longevity and health.

Side Effects of Caloric Restriction

While the potential benefits of caloric restriction and longevity are enticing, it's crucial to acknowledge the flip side and seek expert advice. Extreme caloric restriction, especially when not approached with caution, can lead to unintended consequences. It is imperative to shed light on the potential dangers and emphasize the importance of walking the line between reaping the benefits and safeguarding overall well-being.
One of the primary concerns is rapid weight loss, which, when excessive, can strain the body and reduce its ability to function optimally. If the body is deprived of essential nutrients, you can experience impaired immune function, cardiovascular complications, hair loss, hormone imbalances, compromised bone health, and impaired mental health.8 It's a reminder that, in the pursuit of caloric restriction longevity, an extreme approach can sometimes undermine the very goal we seek to achieve.

Different Ways to Achieve Caloric Restriction Safely

Recognizing the potential dangers of extreme caloric restriction, this section navigates through different approaches to safely achieve a reduction in calorie intake. The emphasis here is on maintaining essential nutrient intake while strategically reducing caloric consumption.
  • One effective strategy involves focusing on nutrient-dense foods that provide the maximum nutritional value per calorie. This ensures that even with fewer calories, the body receives the essential vitamins, minerals, and antioxidants crucial for optimal functioning. Center your diet around whole foods rather than processed ones with excessive sugar. For example, lean meats and legumes are excellent sources of amino acids, and fruits like oranges and strawberries are high in vitamin C.
  • Another avenue is mindful eating, a practice that encourages awareness of hunger and fullness cues. By tuning into the body's signals, individuals can often naturally regulate their calorie intake without resorting to rigid dietary restrictions.
  • Additionally, intermittent fasting, which alternates between periods of eating and fasting, offers a more structured approach to caloric restriction. It provides a flexible framework that aligns with individual preferences and lifestyles.
