What happens if an individual fasts for 24 hours? Know its benefits, potential risks, and more
The body initially uses stored glucose for energy, then breaks down glycogen and fat for fuel.
Fasting can stimulate autophagy, a process that recycles damaged cells and proteins. However, it can also lead to dehydration, nutrient deficiencies, and other health issues. Certain individuals, such as pregnant women, children, and those with medical conditions, should consult their healthcare provider before fasting to ensure safety and minimize potential risks.
Understanding the body's response to
24-hour fasting
When an individual fasts for 24 hours, their body undergoes several changes to adapt to the lack of food intake. According to MedicalNewsToday, here's a breakdown of what happens:
Initial response (0-12hours): The body uses stored glucose (sugar) for energy. As glucose levels deplete, the body begins to break down stored glycogen in the liver and muscles.
Ketosis (12-24 hours): As glycogen stores are depleted, the body starts to break down fat for energy, producing ketones in the process.
Autophagy: Fasting for 24 hours can stimulate autophagy, a natural process where the body recycles and removes damaged or dysfunctional cells and proteins.
Benefits of 24-hour fasting
Harvard Health Publishing suggests that 24-hour fasting can have several benefits, including:
Weight loss: Fasting can lead to weight loss due to reduced calorie intake and increased fat burning.
Improved insulin sensitivity: Fasting has been shown to improve insulin sensitivity, reducing the risk of developing type 2 diabetes.
Increased Human Growth Hormone (HGH): Fasting has been linked to increased production of HGH, which can help with weight loss and muscle gain.
Enhanced cellular cleaning: Autophagy can help remove damaged or dysfunctional cells and proteins, potentially reducing the risk of chronic diseases.
Potential risks and considerations of 24-hour fasting
While 24-hour fasting can be beneficial for some, according to reports it's essential to consider the potential risks and take necessary precautions:
Dehydration: Fasting can lead to dehydration if not enough fluids are consumed. It's crucial to drink plenty of water during fasting periods.
Social and emotional challenges: Fasting can be challenging socially and emotionally, especially for those with a history of disordered eating.
Nutrient deficiencies: Fasting for extended periods can lead to nutrient deficiencies if not planned properly.
Hormonal changes: Fasting can affect hormone levels, including insulin, cortisol, and leptin. Individuals with hormonal imbalances or certain medical conditions should consult their healthcare provider before fasting.
Who should avoid 24-hour fasting?
According to the National Institute of Aging, certain individuals should avoid 24-hour fasting or consult their healthcare provider before attempting it:
Pregnant or breastfeeding women: Fasting can deprive the fetus or baby of essential nutrients.
Children and teenagers: Fasting can affect growth and development in young individuals.
Individuals with certain medical conditions: Those with diabetes, kidney disease, or other conditions that require careful management should consult their healthcare provider before fasting.
Senior citizens: Fasting can lead to malnutrition and dehydration in older adults, especially if not planned carefully.

Sleepless nights? These ancient Indian and Chinese exercise hacks might hold the key to better sleep, says new study
Synopsis With over 16% of the global population suffering from insomnia, a new study offers hope beyond pills and therapy. It suggests that daily physical activities; especially yoga, Tai Chi, walking, and jogging—can naturally enhance sleep duration and quality. These accessible routines help deactivate stress responses and reset the body's rhythm, making sleep a more achievable dream. iStock A recent meta-analysis has revealed that gentle exercises like yoga, Tai Chi, walking, and jogging may significantly improve sleep quality, rivaling the benefits of cognitive behavioral therapy for insomnia. (Image: iStock) Related Insomnia is no longer just a personal frustration—it's a global epidemic. According to the latest research, about 16.2% of the world's population struggles with insomnia, and nearly 8% face its more severe form. In the United States alone, a study by the Centers for Disease Control and Prevention revealed that 14.5% of adults recently had trouble falling or staying asleep. While cognitive behavioral therapy for insomnia (CBT-i) remains the gold standard in treatment, it's not always accessible to everyone. It often involves multiple sessions with trained therapists—time-consuming and sometimes costly. For those seeking a more approachable solution, movement may be the medicine. A new meta-analysis reviewed studies exploring how physical activity can impact sleep and found that yoga, Tai Chi, walking, and jogging were powerful allies against insomnia. Yoga, known for its gentle stretches and mindful breathing, was shown to increase sleep time by nearly two hours and improve sleep efficiency by 15%. Tai Chi, a slow, meditative martial art with its origins from China, not only improved sleep quality scores but also had long-lasting effects that lasted up to two years, according to the study. Walking and jogging also showed promising results. These simple aerobic activities led to a significant drop in insomnia severity, reducing stress and helping the body reset its internal clock. This research was first reported by Medical News Today, which highlighted expert insights into why these activities might be so effective. Dr. Leah Kaylor, a clinical psychologist specializing in trauma and sleep, explained that exercise may help deactivate the sympathetic nervous system—the body's fight-or-flight response—and increase parasympathetic activity, the calming 'rest-and-digest' mode essential for sleep. Modern life, it seems, is working against our need for sleep. High-pressure careers, non-stop digital stimulation, emotional stress, and even the constant glow of artificial light are all contributors to chronic sleeplessness. Kaylor and neuroscientist Dr. Jonathan Cedernaes both noted that even worrying about sleep itself can spiral into deeper insomnia, especially for those already struggling with anxiety or depression. But this is where gentle movement can offer something deeper than just physical benefit. It provides rhythm, predictability, and calm—qualities often missing in a racing mind. Breath-led activities like yoga and Tai Chi, for instance, can regulate cortisol and improve vagal tone, leaving the body more ready to rest.

Maximizing Bodybuilding Gains with the Right HGH Dosage: A Step-by-Step Guide
If you go to the gym, you may have heard about Human Growth Hormone (HGH). Bodybuilders talk about it all the time. Some use HGH regularly, while others are planning to take it. If you wonder why bodybuilders are interested in this supplement, you will be surprised to hear what HGH brings to the table. You can benefit from HGH in various ways. Do you want to lose weight and gain muscle? Are you looking for a safe way to recover faster after a heavy workout? Do you want to maintain peak performance during the whole workout session? HGH can help you achieve your goals only if you use the correct dosage. If you use too little HGH, you can't see optimum results. On the other hand, taking too much dosage has a risk of potential side effects. In this guide, we will break down HGH dosage for bodybuilders. You will also learn secrets to get the best results and pro tips for safe use. Let's get started! How Does HGH Help Bodybuilders to Get a Good Physique? Want to know how HGH works in bodybuilding? Let us give you a brief about the basics of growth hormones. It is a natural hormone in your body. Your pituitary gland releases it. HGH exclusively helps with cell regeneration, tissue repair, and muscle growth. That's why bodybuilders who are taking HGH regularly gain larger muscles and more energy. However, growth hormones and age are negatively correlated. GH levels peak at puberty and then gradually slow down. Many athletes and bodybuilders struggle with their performance. So, they take HGH to maintain their energy levels and enhance their workout capacity. When you combine HGH therapy and an intense workout, you will achieve maximum gain, from lean muscle to improved recovery. HGH therapy can help you: Recover faster Build muscle Burn fat Boost stamina Enhance overall performance Why does HGH Dosage Matter in Bodybuilding? Now you know how HGH helps you and what you can gain from it. But the problem is you can't take this supplement as much as you want. It is a powerful substance, and the right dosage is the key. Do you know why HGH gets a bad rep? It's because many bodybuilders are tempted by the short-term gains. So, they use higher dosage that may lead to severe issues. The common side effects are joint pain, headache, or swelling. On the other hand, many HGH users don't take the prescribed dosage. They irregularly use too little GH. As a result, they don't see better performance. That's why you must use the correct HGH dosage to maximize your gains. Are you a beginner in this HGH world and confused about how much to take? Don't worry. We have got you covered. Here, we will walk you through the complete HGH dosage for bodybuilding, including the timing. Step-by-Step Guide to HGH Dosage for Bodybuilding What's the correct HGH dosage for bodybuilders? Though there are some standards but it's not the same for all because everyone has unique health conditions and goals. You open the vial and inject as much HGH as you want into your body! It's not that simple. Your healthcare physician pulls your blood and runs some lab tests. They determine the correct dosage based on your lab results and your goal. Step 1: Determine Your HGH Goals Why do you want to use HGH? Is it for muscle growth or fat loss? Or do you want to enhance your workout capacity? Are you a professional bodybuilder or just a regular athlete? Think about your unique needs and identify your HGH goals. This will help you achieve your bodybuilding gains efficiently. Most importantly, your doctor prescribes your HGH dosage based on your bodybuilding plans. For muscle growth or fat loss, you need a higher dosage. On the other hand, a lower dosage is enough if you want to just improve your energy during a workout. Step 2: Consult with Your Physician Are you considering taking HGH for bodybuilding? You should contact your healthcare provider because they can provide expert guidance. HGH is not for everyone. Many people can't use it due to their health status. So, before starting your HGH journey, consult your physician. They know your medical history. So, your doctor can easily determine your HGH cycle and personal dosage. If you have any health issues, they can warn you and monitor your progress over time. Step 3: Start Your Beginner Cycle with Lower Dosage Don't get excited about HGH and overload your system. If you are a beginner in bodybuilding and haven't used HGH before, the doctors recommend playing the safe side. That means you should start with a lower dosage and increase gradually. The HGH beginner cycle starts with 2 IU (International Units) per day. Continue this recommended amount for about 2 weeks and check how your body responds to it. For many bodybuilders, the lower dosage should perfectly adjust with their systems without causing any trouble. However, during the beginner cycle with the recommended amount of HGH, if you are not feeling okay or experience side effects, reach out to your physician. Your doctor will adjust the dosage, mostly lowering it to 1.5 or 1 IU. Step 4: Find the Right Dosage Your first HGH cycle is crucial because your body may react negatively or show some side effects. You should regularly visit your physician during your cycle. They will examine your health status and do some bloodwork if necessary. Once they find everything is okay, and your body perfectly adapts to the HGH therapy, they may increase it to a higher dosage. For maximum gains, the doctors prescribe the optimal dosage, ranging between 3 IU to 5 IU per day. After using HGH for a while without any issue, it can be easy for you to find the right dosage. For instance, 3 IU is a suitable middle ground for most bodybuilders. However, the scenario is different for experienced ones. If you are a professional athlete, you may use 4 IU to 5 IU daily for maximum gains. Of course, consult your doctor before increasing the dosage. Don't rush to the higher dosage. Start with low and let your body adapt. Step 5: Use HGH at the Right Time for Optimum Results When it comes to HGH therapy, timing is key for getting the best progress. You can take HGH in the morning (on an empty stomach) or at night (30 minutes before bed). Many bodybuilders use it at night to mimic our natural GH production. Also, many found remarkable results when taking it before or after a workout. Want faster recovery? Take it after an intense workout. Conclusion HGH can provide comprehensive benefits only if bodybuilders use it with the right dosage and at the perfect time. Do you want to use HGH for optimum results? You should take a low dose first and change it over time. Also, inform your physician if you face any complication. Also, ensure you use authentic and genuine products from reliable sources like HGH Vallarta. We hope this guide will help you find the proper HGH dosage for maximum gains.

How often should you poop in a day? The answer might surprise you
We all have our rhythms, some go multiple times a day, others only once a week. No two people are the same, and that's okay. But when what's 'normal' changes suddenly, or discomfort sets in, your gut may be signalling you to pay attention. Tired of too many ads? go ad free now According to Medical News Today, healthy bowel frequency ranges widely—from as few as three times a week to as often as three times a day—and it's your consistency that matters most. That means if you regularly go once every other day without pain or strain, that can be perfectly healthy.
