Unlocking the Benefits of Intermittent Fasting

Intermittent fasting (IF) may not seem new for those who skip breakfast. Still, because marketing geniuses from the breakfast cereal industry have told us for decades that a “healthy” breakfast starts with sugared flakes and squares from a box, many of us crave breakfast when we wake up. I do. Right after I get my coffee fix, which may not be necessary physiologically, but my brain says otherwise and usually runs the show.

Studies show students score higher when they have enjoyed healthy food choices before school, and the word breakfast translates to “Breaking the fast” after a night of sleep. So eating soon after waking makes sense. Unfortunately, sugary breakfasts or heavy carb and meat choices tend to bog us down soon after eating. Ideally, a choice like oatmeal that doesn’t cause a sugar rush and lasts for hours would be ideal. But let’s get back to zero breakfast ideas.

 Intermittent fasting is a popular dietary strategy that alternates between periods of eating and fasting. Rather than focusing on what to eat, IF emphasizes when to eat. Proponents claim it can help lose weight, improve metabolic health, and extend lifespan. Its appeal lies in its simplicity and flexibility, as it doesn’t require counting calories or following a restrictive diet. IF taps into our evolutionary past, where food availability was inconsistent, and fasting was a natural part of life.

Types of Intermittent Fasting

There are several different ways to practice intermittent fasting, each with varying fasting and eating windows:

  1. 16/8 Method: One of the most common and sustainable methods that I have found and use myself is this approach. It involves fasting for 16 hours daily and limiting my eating window to 8 hours. You can set any time you like, but I skip breakfast and eat from noon until 8 p.m. It’s popular because it fits into daily life without requiring significant adjustments.
  2. 5:2 Diet: On the 5:2 diet, participants usually eat five days a week and drastically reduce calorie intake to around 500-600 calories on the remaining two days. These fasting days, such as Monday and Thursday, are typically non-consecutive, allowing for flexibility.
  3. Eat-Stop-Eat: This involves a 24-hour fast once or twice weekly. For example, you might finish dinner at 7 p.m. and not eat again until 7 p.m. the next day. This method can be more challenging but offers a more extended fasting period, which may enhance benefits.
  4. Alternate-Day Fasting: As the name suggests, alternate-day fasting involves fasting every other day. Some variations allow a small number of calories (around 500) on fasting days, while others require complete fasting. This can be a rigorous method, and adherence is often a challenge.
  5. Warrior Diet: The Warrior Diet involves eating small amounts of raw fruits and vegetables during the day and having one large meal at night. The eating window is typically around four hours in the evening, making this method one of the most extreme forms of intermittent fasting.
  6. Spontaneous Meal Skipping: Instead of following a strict schedule, some people skip meals when they’re not hungry or don’t have time to eat. This informal approach can be easier to integrate into daily life, as it doesn’t require planning.

How Intermittent Fasting Works

When we eat, the body uses the calories from the meal for immediate energy, especially glucose. Insulin levels rise to help transport glucose into the cells for energy or storage. When fasting, insulin levels drop, signaling the body to burn stored energy (fat). This metabolic shift is the foundation of the weight loss and metabolic health benefits often associated with intermittent fasting.

During fasting periods, the body transitions into a state known as ketosis, where it begins to break down fat into fatty acids and ketones for energy. This state is similar to a ketogenic diet, which encourages fat metabolism. However, with IF, this metabolic switch occurs periodically rather than constantly, which some researchers argue makes it more sustainable in the long term.

Benefits of Intermittent Fasting

  1. Weight Loss and Fat Loss: One of the primary reasons people turn to intermittent fasting is weight loss. By restricting eating to certain windows, overall calorie intake is often reduced, leading to weight loss. Additionally, fasting periods encourage the body to use fat for energy, which can further accelerate fat loss. Studies suggest that IF can be as effective for weight loss as traditional calorie restriction diets, with some finding it even easier to stick to.
  2. Improved Insulin Sensitivity: IF can reduce insulin resistance, lower blood sugar levels, and protect against Type 2 diabetes. By allowing insulin levels to drop, the body becomes more sensitive to insulin, improving how it processes glucose and reducing the risk of developing metabolic diseases.
  3. Cellular Repair and Autophagy: Fasting triggers cellular repair processes, including autophagy. Autophagy is the body’s way of cleaning out damaged cells and regenerating new, healthy ones. This process is critical in protecting against diseases like cancer and Alzheimer’s, as it removes dysfunctional components that can accumulate over time.
  4. Heart Health: Intermittent fasting can improve various risk factors for heart disease, including lowering LDL cholesterol, reducing triglycerides, decreasing blood pressure, and reducing inflammation. These improvements collectively reduce the risk of cardiovascular diseases, which are a leading cause of death worldwide.
  5. Brain Health and Longevity: Fasting may benefit brain health by promoting the production of a brain-derived neurotrophic factor (BDNF), which is essential for learning, memory, and cognitive function. Low levels of BDNF are linked to conditions like depression and cognitive decline. Moreover, fasting has been shown to increase the brain’s resistance to stress and neurodegeneration, potentially reducing the risk of diseases like Alzheimer’s and Parkinson’s.
  6. Increased Human Growth Hormone (HGH): Fasting has been shown to increase levels of human growth hormone (HGH), which plays a crucial role in fat loss, muscle gain, and overall metabolic health. Higher HGH levels can aid in weight loss, recovery, and muscle preservation, particularly during periods of caloric deficit.
  7. Simplified Eating and Improved Focus: One unexpected benefit of intermittent fasting is the simplicity it brings to daily life. By reducing the number of meals, meal planning and preparation become easier. Additionally, many people report improved focus and mental clarity during fasting periods, as they aren’t distracted by food or digestion.

Potential Downsides and Risks

While intermittent fasting has many potential benefits, it may not suit everyone. I do get hungry in the morning, but the better my choices for my later meals, the less effect I notice.

Some common concerns and potential risks include:

  1. Hunger and Cravings: One of the most immediate challenges of intermittent fasting is hunger, especially during the early days of adjusting to a new eating pattern. For some, this can lead to overeating during the eating window, which may counteract any potential benefits.
  2. Disordered Eating: For people with a history of eating disorders, intermittent fasting may exacerbate unhealthy relationships with food. The rigidity of fasting schedules could trigger obsessive behaviors around food and eating patterns.
  3. Fatigue and Irritability: During fasting periods, particularly in the beginning, many people experience fatigue, irritability, and difficulty concentrating. These symptoms often subside as the body adapts to the new eating pattern, but they can be a significant barrier to maintaining the routine. Instead of jumping into something at full speed, work your way up to your chosen total fast hours. Start with an extra hour of fast for a few days, then add a second hour and so on.
  4. Nutrient Deficiencies: Intermittent fasting, especially when combined with calorie restriction, could lead to nutrient deficiencies. To avoid this, it is important to focus on nutrient-dense foods while eating windows and ensure that all essential vitamins and minerals are consumed.
  5. Hormonal Changes: IF can affect hormones, particularly in women. Some research suggests that fasting may disrupt the menstrual cycle and fertility, particularly when combined with excessive calorie restriction or extreme exercise. Women considering intermittent fasting should pay close attention to how it affects their bodies and adjust accordingly.
  6. Exercise Performance: Some people find fasting negatively impacts their energy levels during workouts, particularly high-intensity or endurance exercises. However, others report improved performance, especially when their body becomes fat-adapted and more efficient at using fat as fuel.

Conclusion

Intermittent fasting is a flexible and practical approach to weight management, metabolic health, and potentially increasing longevity. By incorporating fasting periods, the body can tap into its fat stores and undergo various beneficial processes such as autophagy, insulin sensitivity, and improved heart and brain health. However, intermittent fasting is not a one-size-fits-all approach. Before starting, individuals must consider their unique needs, goals, and potential risks and consult with healthcare professionals if necessary.

For those who find it sustainable, intermittent fasting can be a simple yet powerful tool for improving overall health and wellness.

Understanding Kidney Health: Why Hydration Matters

I live in a very hot climate. Just walking around the block can be a challenge when it’s 115 degrees. So, I do a lot of hydrating, from fruit smoothies to Kabocha, to the occasion seltzer or soda. You should also be eating fruits and vegetables with high water content like strawberries, watermelon, cantaloupe, peaches, oranges, and cucumbers because the truth is that we all take our kidneys for granted. Mostly they just need plenty of water.

Yes, our kidneys work very hard every day to maintain overall health. Despite their small size (each kidney is about the size of a fist), they perform several crucial and complex functions that keep the body’s internal environment stable and balanced. The kidneys are vital organs in the urinary system, filtering waste products from the blood, regulating electrolytes, balancing fluids, and even playing a role in hormone production.

If you’ve been taking your kidneys for granted, don’t feel bad. We all do that from time to time. And while you’re eating better and hydrating, you might want to consider a sponsored kidney cleanse supplement before getting a closer look at how hard the kidneys work. As with all changes you initiate with your body from herbs to supplements to drug routines, you should talk to your doctor first.

Critical Functions of the Kidneys

  1. Filtering Blood
    • The kidneys filter about 150-180 liters of blood daily but only produce 1-2 liters of urine. They remove waste products, toxins, and excess substances (such as water, salts, and urea) from the blood, concentrate them into the urine, and then excrete them.
    • Nephrons, the tiny kidney filtering units, are responsible for this task. Each kidney contains around 1 million nephrons. This vast number of nephrons ensures that the kidneys can efficiently filter blood and remove waste.
  2. Regulating Fluid and Electrolyte Balance
    • Kidneys regulate the body’s fluid levels by controlling how much water is reabsorbed into the bloodstream and how much is excreted in urine.
    • They also maintain electrolyte balance, managing critical minerals like sodium, potassium, calcium, and magnesium, essential for various bodily functions, including nerve transmission, muscle function, and blood pressure regulation.
  3. Maintaining Acid-Base Balance
    • The kidneys help regulate the body’s pH levels by excreting hydrogen ions (which are acidic) and reabsorbing bicarbonate (a buffer that neutralizes acid). This ensures that the blood’s pH stays within a narrow range, critical for all enzymatic and metabolic processes in the body.
  4. Regulating Blood Pressure
    • The kidneys help regulate blood pressure by controlling the balance of salt and water in the body and releasing the enzyme renin. Renin helps regulate the contraction and relaxation of blood vessels, affecting blood pressure.
    • The renin-angiotensin-aldosterone system (RAAS), partially controlled by the kidneys, plays a critical role in long-term blood pressure regulation.
  5. Producing Hormones
    • Erythropoietin: The kidneys produce this hormone, which stimulates the production of red blood cells in the bone marrow. This is especially important when oxygen levels in the blood are low.
    • Calcitriol: This is the active form of vitamin D, produced by the kidneys. Calcitriol helps regulate calcium levels in the blood and supports bone health.
    • Renin: As mentioned earlier, this hormone is part of the process that helps control blood pressure.
  6. Detoxification
    • In addition to filtering waste from normal metabolic processes, the kidneys help remove toxins from food, drugs, and environmental pollutants, preventing their buildup in the body.
  7. Balancing Blood Osmolarity
    • The kidneys ensure that the concentration of solutes (salts, glucose, and other particles) in the blood is within a specific range. This balance is critical for maintaining the health of cells and tissues throughout the body.

How Hard the Kidneys Work: Daily Effort

The workload of the kidneys is continuous and vital to sustaining life. Given the complexity of their functions, kidneys are always active, whether you are awake or asleep. Their role in filtering blood and maintaining homeostasis is demanding, mainly because they:

  • Filter about 50 gallons (150 liters) of blood each day.
  • Produce urine from excess waste and fluids.
  • Constantly adjust to the body’s changing needs, such as eating, drinking, or engaging in physical activity.

Factors That Increase Kidney Workload

Several factors can increase the workload of the kidneys or challenge their ability to function efficiently. While the kidneys are resilient, prolonged stress can lead to kidney damage over time. Some of these factors include:

  1. High Blood Pressure (Hypertension)
    • High blood pressure forces the kidneys to work harder to filter blood, which can damage the delicate blood vessels in the nephrons. Over time, this can lead to chronic kidney disease (CKD).
  2. High Sugar Intake (Diabetes)
    • High blood sugar levels in people with diabetes can damage the small blood vessels in the kidneys. This makes it harder for the kidneys to filter blood properly and can eventually lead to diabetic nephropathy (kidney damage due to diabetes).
  3. High Protein Diets
    • Consuming large amounts of protein increases the workload of the kidneys because they must filter and excrete the nitrogenous waste products (mainly urea) that result from protein metabolism.
    • Although moderate protein intake is not harmful to healthy kidneys, excessive protein intake over time can stress the kidneys.
  4. Dehydration
    • Not drinking enough water can make it harder for the kidneys to flush out waste products, leading to more concentrated urine. Chronic dehydration can lead to kidney stones and other complications.
  5. Toxins and Medications
    • Certain medications, especially when taken long-term (e.g., NSAIDs like ibuprofen), as well as alcohol and certain toxins, can stress the kidneys and potentially lead to damage if not used carefully.
  6. High Salt Diets
    • Excessive sodium intake can increase blood pressure and the kidneys’ work to maintain fluid and electrolyte balance.

Signs Your Kidneys Are Under Stress

When the kidneys are struggling or under stress, some warning signs may appear, although kidney disease can often progress without obvious symptoms until it is advanced. Signs that your kidneys may be working too hard or not functioning properly include:

  • Fatigue and weakness (due to low red blood cell count or anemia caused by reduced erythropoietin production).
  • Swelling (edema), especially in the legs, ankles, feet, or hands, due to fluid retention.
  • Changes in urination: Decreased or increased urine output, dark-colored or foamy urine, or pain during urination.
  • High blood pressure is a sign that the kidneys are not effectively regulating blood pressure.
  • Nausea, vomiting, or loss of appetite: These can be symptoms of uremia, a buildup of waste products in the blood due to kidney dysfunction.
  • Itching or dry skin: This is related to the accumulation of waste products that the kidneys can no longer filter properly.

How to Support Your Kidneys

To keep your kidneys functioning optimally and reduce their workload, consider the following strategies:

  1. Stay Hydrated: Drinking plenty of water helps the kidneys filter waste effectively and prevents kidney stones.
  2. Eat a Balanced Diet: Limit excess salt, sugar, and unhealthy fats. Focus on whole grains, fruits, vegetables, and lean proteins.
  3. Monitor Blood Pressure: Keep your blood pressure in check to reduce the strain on your kidneys.
  4. Control Blood Sugar: If you have diabetes, managing blood sugar levels is critical for protecting your kidneys.
  5. Limit Alcohol and Avoid Smoking: Both alcohol and smoking can damage the kidneys over time.
  6. Exercise Regularly: Physical activity helps maintain a healthy weight, supports heart health, and reduces the risk of kidney damage.
  7. Avoid Overuse of NSAIDs: Prolonged use of nonsteroidal anti-inflammatory drugs (like ibuprofen) can harm the kidneys, so use them sparingly and consult a doctor for long-term pain management.

Conclusion

Our kidneys perform vital and complex tasks essential for overall health, from filtering waste to balancing fluids and electrolytes. While they are highly efficient and resilient, they can become overworked due to factors like poor diet, dehydration, or chronic health conditions like diabetes and hypertension. By adopting kidney-friendly habits such as staying hydrated, eating a balanced diet, exercising, and avoiding harmful substances, you can support your kidneys in their hard work and ensure they function optimally for a lifetime.

Other high-water content foods to considerer include celery, zucchini, lettuce, tomatoes, bell peppers, and cauliflower.

Red Yeast Rice: Natural Cholesterol Management for Heart Health

Red yeast rice is a traditional Chinese medicinal product made by fermenting rice with a specific strain of yeast called Monascus purpureus. It has gained popularity as a natural supplement for lowering cholesterol due to its content of monacolin K, a compound chemically identical to the active ingredient in the prescription drug lovastatin (a statin). While red yeast rice may benefit cholesterol management, its safety and effectiveness come with some critical considerations.

  1. Cholesterol-lowering Effects
    • Red yeast rice contains monacolin K, which inhibits the enzyme HMG-CoA reductase, responsible for cholesterol production in the liver. This mechanism is identical to how statins lower cholesterol.
    • Studies have shown that red yeast rice can effectively lower total cholesterol, LDL cholesterol (the “bad” cholesterol), and triglycerides and slightly increase HDL cholesterol (the “good” cholesterol). Some research indicates that it can reduce LDL cholesterol by 20-30%, similar to the effects seen with prescription statins.
    • Meta-analyses and clinical trials: Multiple studies and meta-analyses confirm that red yeast rice supplements can reduce cholesterol levels, especially in people with hypercholesterolemia (high cholesterol). A 2015 review found that red yeast rice significantly lowered LDL cholesterol, total cholesterol, and triglycerides compared to a placebo.
  2. Potential Cardiovascular Benefits
    • By lowering cholesterol, red yeast rice may reduce the risk of heart disease, atherosclerosis, and other cardiovascular issues associated with high cholesterol.
    • Some studies suggest that regular use of red yeast rice may help prevent recurrent heart attacks in individuals with a history of cardiovascular disease.
  3. Additional Compounds
    • In addition to monacolin K, red yeast rice contains other bioactive compounds, such as unsaturated fatty acids, phytosterols, and isoflavones, which may contribute to its cholesterol-lowering and heart-protective effects. These compounds may also provide anti-inflammatory and antioxidant benefits, promoting cardiovascular health.

Safety and Potential Risks of Red Yeast Rice

While red yeast rice can be effective for lowering cholesterol, its use as a supplement comes with safety concerns, especially because it is similar to statins.

1. Risk of Side Effects Similar to Statins

Since monacolin K is chemically identical to lovastatin, red yeast rice can produce the same side effects as prescription statins. Common side effects include:

  • Muscle pain or weakness (myopathy): One of the most commonly reported side effects, which can progress to a more serious condition called rhabdomyolysis if untreated.
  • Liver damage: Red yeast rice can affect liver function, particularly at higher doses. Monitoring liver enzymes is recommended for long-term users or those at risk of liver disease.
  • Gastrointestinal issues: Some people report nausea, bloating, gas, and indigestion when using red yeast rice.

In people sensitive to statins or those with existing health issues, these side effects may be more pronounced.

2. Variability in Supplement Quality

One of the primary concerns with red yeast rice supplements is the inconsistency in the amount of monacolin K across different products. The U.S. Food and Drug Administration (FDA) does not strictly regulate red yeast rice supplements as prescription medications, leading to variability in potency and quality.

  • Some products contain little to no monacolin K, making them ineffective.
  • Others may contain high levels, increasing the risk of side effects similar to prescription statins.

Contaminants: Additionally, poorly produced red yeast rice supplements may contain harmful contaminants, such as citrinin, a byproduct of the fermentation process that is toxic to the kidneys.

3. Possible Drug Interactions

Red yeast rice can interact with several medications, similar to statins. Key interactions include:

  • Other cholesterol-lowering medications: Combining red yeast rice with statins or other cholesterol-lowering drugs can increase the risk of side effects, particularly muscle pain and liver damage.
  • Blood thinners (e.g., warfarin): Red yeast rice may increase the risk of bleeding in people taking anticoagulants.
  • Medications metabolized by the liver: Because red yeast rice affects liver enzymes, it can interfere with how the body processes certain drugs, leading to increased or decreased efficacy.

4. Not Suitable for Everyone

Red yeast rice may not be appropriate for individuals with certain conditions, including:

  • Pregnancy and breastfeeding: Red yeast rice should not be used by pregnant or breastfeeding women due to the lack of research on its safety and potential for harm to the developing baby.
  • Liver or kidney disease: Individuals with liver or kidney problems should avoid red yeast rice due to the risk of further damage.
  • History of statin intolerance: Those who have experienced adverse reactions to statins may experience similar effects with red yeast rice.

Guidelines for Safe Use of Red Yeast Rice

If you are considering using red yeast rice to manage cholesterol, it’s essential to follow these guidelines to maximize safety and effectiveness:

  1. Consult a Healthcare Provider. Before starting red yeast rice, talk to your doctor or a healthcare professional, especially if you are on other medications or have underlying health conditions. A doctor can recommend the proper dosage and monitor for potential side effects, including liver function tests.
  2. Choose High-Quality Supplements. Look for red yeast rice products that have been third-party tested for quality and purity. This can reduce the risk of contaminants like citrinin and ensure the product contains the appropriate amount of monacolin K. Avoid products from unreliable or unverified manufacturers.
  3. Monitor for Side Effects If you experience any signs of muscle pain, weakness, liver issues (such as yellowing of the skin or eyes), or other unusual symptoms, discontinue use and seek medical attention immediately. Regular blood tests for liver function and muscle health are recommended for long-term use.
  4. Follow Recommended Dosage Typical dosages for red yeast rice range from 600 mg to 1,200 mg per day, but this can vary based on the concentration of monacolin K in the product. Avoid taking excessive doses, as this increases the risk of side effects.
  5. Consider Complementary Approaches While red yeast rice can help manage cholesterol, combining it with other lifestyle changes can improve results and reduce the need for supplements. This includes:
    • A heart-healthy diet: Focus on eating more fruits, vegetables, whole grains, and healthy fats (like omega-3s from fish or flaxseed) while reducing saturated fats and cholesterol-rich foods.
    • Exercise: Regular physical activity helps boost HDL cholesterol and improve cardiovascular health.
    • Maintain a healthy weight: Weight management can reduce LDL cholesterol and improve overall heart health.

Conclusion

Red yeast rice can be an effective natural supplement (sponsored) for lowering cholesterol due to its monacolin K content, which works similarly to prescription statins. However, the supplement comes with potential risks, including side effects like muscle pain, liver damage, and drug interactions. The variability in product quality and the potential presence of harmful contaminants like citrinin are also concerns.

For most individuals, it is essential to approach red yeast rice with caution, use it under the guidance of a healthcare professional, and ensure it is part of a broader strategy that includes a heart-healthy diet and regular exercise. If you are sensitive to statins or have underlying health conditions, alternative cholesterol-lowering strategies may be more suitable.
