Fasting for Health and Sustainability: Benefits for You and the Earth

Intermittent Fasting gives your body a much-needed break to clean up and restore. The response to fasting can vary based on individual factors like metabolism, overall health, and hormonal balance. It’s important to approach fasting with a personalized plan that considers your unique health needs and lifestyle to maximize benefits and minimize potential risks.

Starting to fast

My journey into Intermittent Fasting began with a simple 12-hour fast—from 8 PM to 8 AM the next day. Each week, I extended the fast by two hours until I reached a 16-hour fast, meaning I would skip breakfast. As I progressed, I occasionally increased the fast to 22 hours and had only One Meal a Day (OMAD). 

Key Adjustments:

  • Cutting out bread, cereals, and pasta helped reduce my snacking urges and constant hunger.
  • Eating less frequently allowed me to buy more organic and nutritionally rich whole foods.


Benefits For You

Intermittent Fasting can offer a variety of health benefits. Here are some of the most commonly recognized advantages:

  • 🔥 Weight Loss and Metabolic Health:
    Fasting can lead to a reduction in calorie intake and boost metabolism, helping with weight loss. It can also improve metabolic flexibility, which is the body’s ability to switch between burning carbs and fats efficiently.

  • 📉 Improved Insulin Sensitivity:
    Fasting can lower blood sugar levels and improve insulin sensitivity, reducing the risk of type 2 diabetes. Regular fasting reduces insulin resistance, which can help control blood glucose levels.

  • 🧠 Enhanced Brain Function:
    Fasting is believed to support brain health by reducing oxidative stress, inflammation, and the risk of neurodegenerative disorders. It may also boost the production of brain-derived neurotrophic factor (BDNF), a protein that contributes to learning and memory.

  • 🧬 Autophagy and Cellular Repair:
    Fasting activates autophagy, a process where cells remove damaged components. This can help in cell maintenance and is linked to reduced aging and disease processes.

  • ❤️ Heart Health:
    Fasting may improve various risk factors associated with heart disease, including blood pressure, cholesterol levels, triglycerides, and inflammatory markers.

  •  💪 Increased Growth Hormone Secretion:
    Fasting can increase levels of human growth hormone (HGH), which is important for growth, metabolism, weight loss, and muscle strength.

  • 🍏 Improved Digestive Health:
    By temporarily abstaining from food, fasting can help give the digestive system a rest, potentially reducing inflammation and promoting better gut health.

  • 🧘‍♂️ Emotional and Psychological Benefits:
    Many people report feeling more clear-headed and emotionally balanced as a result of fasting. It can also be a way to cultivate discipline and improve one’s relationship with food.

It’s important to approach fasting with caution, especially if you have pre-existing health conditions or are pregnant or breastfeeding. Consulting a healthcare provider before starting any fasting regimen is advisable to ensure it’s done safely and effectively.

For Others

Fasting can have benefits that extend beyond personal health improvements. It can also positively impact others around us and even broader societal aspects. Here are a few ways how fasting can help others:

  • 🌍 Resource Conservation:
    By consuming less food in Western countries, we can influence global food markets and drive down the price of food for other countries. This reduction in demand helps stabilize food prices globally, making essential nutrients more affordable and accessible in developing regions. Furthermore, decreased consumption in affluent areas can reduce the strain on food supply chains, allowing surplus food to be redirected to areas of scarcity. This not only helps in balancing global food distribution but also supports international efforts to combat hunger and food insecurity. Such mindful eating practices, coupled with policies that encourage food sharing and export to needy areas, could significantly enhance food availability and affordability worldwide.

  • 🏥 Healthcare Cost Reduction:
    Fasting can potentially reduce the incidence of lifestyle-related diseases such as obesity, type 2 diabetes, and heart disease. This, in turn, can lower healthcare costs associated with treating these conditions. When people are healthier, it can reduce the burden on healthcare systems and benefit society economically.

  • ⚡ Increased Productivity:
    While the initial adjustment period can be challenging, many people report increased mental clarity and energy levels once they have adapted to fasting. This can lead to improved productivity and performance in both personal and professional settings.

  • 🗣 Promoting Healthy Lifestyles:
    Individuals who fast and share their positive experiences can influence others to adopt healthier eating patterns and lifestyles. This can have a ripple effect, promoting overall community health.

  • 💸 Reducing Inflation
    Reducing mass consumption can potentially have an impact on inflation. When consumers buy less, the demand for goods decreases, which can lead to lower prices if supply remains constant. This can effectively reduce inflationary pressures in the economy. However, the relationship between consumption and inflation is complex and influenced by various factors such as supply chain dynamics, monetary policy, and global economic conditions. Therefore, while reduced consumption can contribute to lower inflation, it’s just one of many factors that influence the overall inflation rate.

In these ways, fasting can contribute positively not just to individual health, but also to societal well-being and cohesion.

For the Earth

Fasting can have several positive impacts on the environment, contributing to sustainability in various ways. Here’s how fasting can help the Earth:

  • 📉 Reduced Resource Consumption:
    By eating less frequently or reducing meal sizes, fasting decreases the overall consumption of food. This leads to a lower demand for food production, which can save water, reduce land use, and conserve energy required for farming, processing, transporting, and storing food.

  • 🗑️ Decreased Food Waste:
    Fasting encourages more mindful eating and food preparation practices, potentially leading to less food being prepared and subsequently wasted. This can significantly reduce the amount of food that ends up in landfills, where it decomposes and produces methane, a potent greenhouse gas.

  • 🌍 Lower Carbon Footprint:
    The production of food, particularly meat and dairy products, is a major source of greenhouse gas emissions. By reducing the frequency of meals, fasting can lower the demand for these products, thus reducing one’s carbon footprint.

  • 🌾 Promotion of Sustainable Agriculture:
    Fasting can increase awareness about the impact of our food choices on the environment. This awareness might encourage more people to choose sustainably produced foods that are better for the environment when they do eat.

  • 🔄 Cultural Shift Towards Minimalism:
    Fasting can inspire a minimalist approach to other aspects of life, including consumer habits. By learning to live with less and prioritizing essentials, fasting can promote a cultural shift towards sustainability beyond just food consumption.

In these ways, fasting benefits individual health and promotes a healthier earth by reducing environmental impact through various channels.

Considerations for Women

Women may experience different effects from fasting, primarily due to hormonal variations affecting metabolism and energy levels. Here are a few considerations for women interested in fasting to promote autophagy:

  • Menstrual Cycle:
    Women should consider their menstrual cycle when planning a fast. Fasting during the follicular phase (the first half of the cycle starting from the first day of menstruation) might be easier and more beneficial than during the luteal phase (the latter half after ovulation), when energy needs can increase and fasting might feel more challenging.

  • Hormonal Sensitivity:
    Some women are particularly sensitive to changes in meal timing and caloric intake, which can impact hormonal balance. For instance, fasting might affect levels of leptin and ghrelin, hormones that regulate appetite and could influence other hormones like estrogen and progesterone.

  • Bone Health:
    Long-term or frequent aggressive fasting may affect bone health negatively in women. It’s important to ensure adequate nutrient intake during eating periods, especially of calcium and vitamin D.

  • Adrenal Stress:
    Women with conditions like adrenal fatigue or high stress may need to approach fasting cautiously, as fasting can potentially increase cortisol levels, exacerbating these conditions.

For women interested in fasting for autophagy, starting with a gentle approach like intermittent fasting or time-restricted eating and observing how their body responds can be a wise strategy. Consulting with a healthcare provider who understands the nuances of fasting in relation to women’s health is always recommended to ensure safety and effectiveness.

  • The 6 biggest benefits of intermittent fasting

    Precision Nutrition
    Intermittent fasting (IF) is lauded for its numerous potential health benefits, though it's important to note that excessive or intense fasting may not necessarily increase these benefits linearly. Here's a summarized list of the six significant advantages associated with IF:

    Slowing Aging: IF may slow down the process of cellular aging, known as cellular senescence, which involves cells deteriorating and failing to divide. Fasting helps reduce the buildup of senescent cells, which can cause inflammation and contribute to various aging symptoms.
    Improving Brain Health: IF could potentially slow cognitive decline by reducing inflammation, aiding glucose and insulin control, and stimulating brain cell repair and neuroplasticity.
    Reducing Type 2 Diabetes Risk: By improving insulin sensitivity and glucose control, IF may lower the risk of type 2 diabetes. A small study showed significant improvements in individuals with type 2 diabetes who adopted fasting, leading to cessation of insulin use.
    Cancer Risk Reduction: IF might slow cancer progression by inhibiting cellular growth, reducing energy supply to cancer cells, and improving the body's response to cancer treatment drugs.
    Enhancing Heart Health: Fasting can benefit heart health by reducing inflammatory markers like C-reactive protein and improving cholesterol and lipid profiles. It may also lower blood pressure and resting heart rate.
    Increasing Fat Loss: IF helps in fat loss through various mechanisms, although this relationship is complex and influenced by individual factors.
    However, it's crucial to consider that IF isn't suitable for everyone. People with certain health conditions, those prone to disordered eating, or individuals who respond poorly to hunger might find fasting more harmful than beneficial. Thus, a personalized approach, often referred to as "IF Lite," which involves eating according to hunger cues rather than a strict schedule, is recommended for those sensitive to the effects of fasting.

    In conclusion, while IF shows promise in several areas of health and longevity, the benefits can vary greatly depending on individual circumstances and should not be viewed as a universal solution. The approach should be tailored to individual needs and health conditions, and ideally, discussed with a healthcare provider.

    National Library of Medicine (NIH)
    Intermittent fasting (IF) is increasingly explored for its potential cardiovascular benefits, as outlined in a comprehensive review that integrates various studies on its impact on heart health. IF protocols, such as time-restricted feeding and alternate-day fasting, have shown promise in reducing risk factors associated with cardiovascular diseases, including atherosclerosis, hypertension, and diabetes. Studies suggest that IF can improve lipid profiles by lowering triglycerides and bad cholesterol levels while enhancing good cholesterol. Additionally, IF may help regulate blood pressure and reduce inflammatory markers like C-reactive protein, which are linked to heart disease. The review also points to IF's potential in aiding weight management and improving metabolic health, which are crucial in preventing and managing heart conditions. Despite these benefits, the review notes that more research is needed to fully understand the mechanisms behind IF's effects on cardiovascular health and to establish more concrete guidelines for its use in clinical settings.

  • Effects of intermittent fasting diets on plasma concentrations of inflammatory biomarkers: A systematic review and meta-analysis of randomized controlled trials.

    Europe PMC
    A meta-analysis of eighteen randomized control trials (RCTs) examined the effects of intermittent fasting (IF) and energy-restricted diets (ERDs) on inflammatory biomarkers in humans, specifically focusing on C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6). The results indicated that both IF and ERDs significantly reduced CRP levels, particularly in overweight and obese individuals and with interventions lasting at least 8 weeks. However, these dietary approaches did not significantly impact TNF-α and IL-6 levels. The study highlights the potential of IF and ERDs to manage inflammation through specific markers like CRP, suggesting their beneficial role in dietary interventions, especially for individuals with higher body mass indexes.

  • How Does Trade Impact the Way GDP Growth and Inflation Comove Across Countries?

    Federal Reserve Bank of Richmond
    The economic brief by Paul Ho, Pierre-Daniel G. Sarte, and Felipe F. Schwartzman in January 2023, titled "How Does Trade Impact the Way GDP Growth and Inflation Comove Across Countries?" explores the significant role of trade in influencing global economic patterns, particularly the comovement of GDP growth and inflation across nations. Despite seemingly minimal direct trade linkages, the study highlights substantial spillovers facilitated through indirect effects in the trade network, amplifying the influence of economic disturbances from one country on others. For instance, inflationary shocks in Europe can substantially affect U.S. inflation, and U.S. monetary policies can have profound impacts on foreign economies. The researchers utilize a sophisticated business-cycle model with multilateral trade to quantify these spillovers, revealing that country-specific shocks can explain a major part of the observed correlations in output growth and inflation across countries. This study underscores the interconnectedness of the global economy through trade, emphasizing the need for comprehensive policy considerations that account for both direct and indirect international economic interactions.

  • Rising Inflation Triggers Shift in Global Consumer Spending

    The article by Jens von Wedel from Oliver Wyman highlights how global inflation has affected consumer spending behaviors. Despite a slight easing of inflation recently, a survey conducted in June 2023 involving 10,000 consumers across nine countries revealed persistent concerns about purchasing power, particularly for essential goods and services. In response to rising prices, a significant majority of consumers are adjusting their spending by seeking cheaper alternatives, reducing overall purchase volumes, and, in some regions, using bulk purchasing to achieve savings. Notably, the article discusses varied regional approaches to cost-saving, such as the group-buying model in Asia and bulk orders in the Middle East, reflecting different consumer strategies to combat inflationary pressures. While essential spending is heavily impacted, discretionary spending on items like apparel and travel shows some resilience, with consumers showing a reluctance to cut back in these areas despite the economic climate. The findings suggest that businesses should consider revising their pricing strategies and product offerings to cater to the more price-sensitive consumer base emerging in this inflationary period.
