🔬 The Science of Fasting Where Ancient Siddha Wisdom Meets Modern Nobel Prize Research 🌿 Introduction What if the secrets of cutting-edge science were already known thousands of years ago? Imagine a Tamil Siddha meditating in a mountain cave and a modern scientist observing cells through a microscope—both arriving at the same truth. In 2016, Yoshinori Ohsumi won the Nobel Prize for discovering Autophagy , a cellular self-cleaning process. Yet, this concept mirrors the ancient Siddha practice of fasting, known as Lankanam . This blog explores how fasting is not starvation—but a powerful internal healing mechanism , almost like performing “surgery” without a scalpel. 🔥 1. Two Perspectives: Jatharagni vs. Autophagy 🪔 The Siddha View: Burning “Amam” In Siddha philosophy, health revolves around Jatharagni —the digestive fire. Constant eating = dumping wet wood into fire Weak digestion = formation of Amam (toxins) These toxins accumulate in joints and organs → disease 👉 When you fast, ...
When it comes to health, it’s not just what we eat—it’s how much we eat that truly matters. In a world where portion sizes have doubled over the decades and fast food is within arm’s reach, understanding the right amount of food we need each day has become essential for staying healthy and preventing chronic diseases.
Let’s explore the science of food portions, practical tips to avoid overeating, and how to find the right balance for your body.
🥗 Why Portion Size Matters
Overeating—even healthy food—can lead to weight gain, digestive issues, and metabolic imbalance. On the other hand, eating too little may deprive your body of the nutrients it needs to thrive. Knowing your body’s energy requirements and understanding portion sizes can help maintain a healthy weight, support organ function, and keep your energy levels steady.
📊 Understanding Daily Caloric Needs
Caloric needs vary based on age, gender, activity level, and health status. Here’s a general breakdown:
| Group | Calories/day (average) |
|---|---|
| Adult women (moderate activity) | 1,800–2,200 |
| Adult men (moderate activity) | 2,200–2,800 |
| Children (ages 6–12) | 1,600–2,000 |
| Teenagers | 2,000–3,000 |
Note: These are estimates. Individual needs may vary based on metabolism and lifestyle.
🍽 Visual Guide to Portions
You don’t always need measuring cups! Use your hands for easy portion control:
-
🥩 Protein (meat, tofu, fish): Palm-sized
-
🥔 Carbs (rice, pasta, bread): One cupped hand
-
🥦 Vegetables: Two cupped hands
-
🧈 Fats (oil, butter, cheese): One thumb
-
🍫 Snacks/sweets: One finger or small palm
🧠 Listen to Your Body
Your stomach sends fullness signals about 20 minutes after you eat. Slow down your meals. Chew well, savor the taste, and give your brain time to catch up with your belly.
💡 Smart Eating Tips for Daily Life
-
🍱 Use smaller plates and bowls to naturally reduce portions.
-
💧 Drink water before meals—it curbs unnecessary hunger.
-
🕑 Stick to a meal schedule to avoid random snacking.
-
📏 Read nutrition labels to understand what constitutes a serving.
-
🥙 Eat mindfully, not distracted—put away your phone or TV.
🌍 Special Note: Cold Weather Consideration
In cold climates, your body burns more calories to stay warm. It’s okay to eat slightly more—just focus on warm, nutrient-dense foods like soups, whole grains, nuts, and root vegetables. Hydration is also crucial in cold weather, even if you don’t feel thirsty.
🔚 Conclusion
Eating the right amount of food isn’t about restriction—it’s about balance. When you understand portion sizes and listen to your body, you fuel yourself better, feel more energized, and reduce the risk of many lifestyle diseases.
Remember: It’s not just about what’s on your plate—it’s how much of it you actually need.
