Nutrition is one of the most talked-about topics in health and wellness, but it’s also one of the most misunderstood. With so much misinformation circulating in popular media, social platforms, and even from well-meaning friends and family, it’s no wonder that many people are confused about what they should be eating for optimal health. From fad diets to unsubstantiated claims, the world of nutrition is full of myths that can prevent individuals from achieving their best health.
In this blog, we’re going to bust some of the most common nutrition myths, backed by science and Ultrahuman’s evidence-based approach to nutrition and performance. Whether you’re a fitness enthusiast, someone trying to lose weight, or just someone wanting to live a healthier life, we’ll help you sift through the noise and get to the truth.
1. Myth: Carbs Are Bad for You
Busted: Carbohydrates are not inherently bad. In fact, they are one of the three macronutrients (along with protein and fat) that our bodies need for energy. Carbohydrates are broken down into glucose, which is the body’s preferred source of fuel, especially for the brain and muscles during physical activity. The real issue comes when you consume refined or highly processed carbohydrates, like white bread, sugary cereals, or baked goods. These types of carbs can cause blood sugar spikes and lead to long-term health issues like obesity and type 2 diabetes.
Ultrahuman’s Evidence-Based Take: Focus on whole, unprocessed carbs such as fruits, vegetables, whole grains, and legumes. These foods provide fiber, vitamins, and minerals that are beneficial for your health. The right carbohydrates can help fuel your workouts and support recovery, making them a crucial part of an athlete’s diet.
Why It Matters:
Carbs are particularly important for endurance athletes or anyone involved in intense physical activities. They help replenish glycogen stores in muscles, supporting sustained energy levels. So, if you’re avoiding carbs altogether, you might be sabotaging your performance and recovery.
2. Myth: You Should Avoid Fats to Lose Weight
Busted: The idea that fat makes you fat is one of the most enduring yet erroneous nutrition myths. Fat is a crucial macronutrient that plays many important roles in the body, including hormone production, brain function, and the absorption of fat-soluble vitamins (A, D, E, and K). While consuming too many calories from any macronutrient can lead to weight gain, eating the right types of fats in appropriate quantities can actually support weight loss.
Ultrahuman’s Evidence-Based Take: Focus on healthy fats from sources like avocados, nuts, seeds, olive oil, and fatty fish (such as salmon). These fats support brain health, reduce inflammation, and can help keep you satiated, reducing the likelihood of overeating. Furthermore, the body burns fat more efficiently during periods of ketosis (such as on a low-carb or ketogenic diet), which may benefit certain individuals.
Why It Matters:
Fats are essential for metabolic health and performance. Certain fats, like omega-3 fatty acids found in fish and flaxseeds, can even reduce inflammation and improve recovery after intense workouts. A balanced intake of healthy fats helps the body function optimally, even if you’re aiming for fat loss.
3. Myth: All Calories Are Equal
Busted: The idea that a calorie is just a calorie, no matter where it comes from, oversimplifies the complex science of nutrition. While calorie balance (calories consumed vs. calories burned) is crucial for weight management, the quality of the calories you consume can have a profound impact on your overall health, energy levels, and body composition.
Ultrahuman’s Evidence-Based Take: The source of calories matters. For example, 100 calories from a sugary soda are metabolized and processed very differently from 100 calories from a serving of leafy greens and lean protein. Whole foods, rich in fiber, vitamins, and minerals, provide more sustainable energy, better satiety, and improved digestion than processed foods that are high in added sugars, unhealthy fats, and sodium.
Why It Matters:
If you’re eating a calorie-dense but nutrient-poor diet, you might experience energy crashes, poor digestion, and nutrient deficiencies. Conversely, nutrient-dense foods will give you more energy, support muscle repair and growth, and contribute to long-term health benefits.
4. Myth: Skipping Meals Helps You Lose Weight
Busted: Many people believe that skipping meals is an effective way to cut calories and lose weight. While intermittent fasting (IF) has been shown to have benefits for some individuals, skipping meals regularly is not a sustainable or healthy approach for most people. In fact, it can lead to overeating later in the day, disrupted metabolism, and even nutrient deficiencies.
Ultrahuman’s Evidence-Based Take: The best approach to weight loss and health is a balanced and consistent eating pattern. This means eating regular, nutrient-dense meals that include a mix of protein, healthy fats, and complex carbohydrates. If you’re practicing intermittent fasting, it’s crucial to ensure that your eating window is filled with whole, nutrient-dense foods to avoid deficiencies and support muscle recovery.
Why It Matters:
Skipping meals can lead to fluctuating blood sugar levels, which can increase hunger and cravings. By eating regular, well-balanced meals, you help stabilize blood sugar, improve energy levels, and prevent overeating later in the day.
5. Myth: Protein Supplements Are Only for Bodybuilders
Busted: While it’s true that bodybuilders and athletes need more protein to support muscle growth and recovery, protein supplements can be beneficial for anyone who wants to improve their health, manage weight, or recover from physical activity. Protein is an essential nutrient that plays a key role in building and repairing tissues, producing enzymes and hormones, and supporting overall body functions.
Ultrahuman’s Evidence-Based Take: Protein intake should be tailored to your individual needs. The average adult needs around 0.8 to 1 gram of protein per kilogram of body weight, but athletes or those involved in resistance training might require more. High-quality protein powders, like whey or plant-based options, can be a convenient way to ensure you're meeting your protein goals, especially if you're struggling to get enough from whole foods.
Why It Matters:
Protein is crucial for maintaining muscle mass, supporting metabolism, and recovering after workouts. Whether you're a casual exerciser or a high-performance athlete, protein supplements can help you reach your dietary goals without added hassle.
6. Myth: Detox Diets Are Necessary to Cleanse Your Body
Busted: The concept of “detoxing” through special cleanses or restrictive diets is not scientifically backed. Our bodies are already equipped with incredibly efficient detoxification systems, namely the liver, kidneys, and digestive system. These organs work around the clock to eliminate toxins naturally. While certain foods can support these processes, extreme detox diets can often do more harm than good.
Ultrahuman’s Evidence-Based Take: Rather than turning to expensive detox juices or supplements, focus on a well-balanced, nutrient-dense diet that supports the body’s natural detoxification systems. Hydration, fiber-rich foods (like vegetables, fruits, and whole grains), and antioxidants from foods like berries, leafy greens, and green tea can help optimize detoxification pathways.
Why It Matters:
Detox diets can lead to nutrient imbalances, fatigue, and even digestive issues. A healthy diet focused on whole, unprocessed foods provides the body with the nutrients it needs to detox naturally and maintain optimal health.
7. Myth: You Should Always Avoid Salt for Heart Health
Busted: While it's true that excessive sodium intake can increase the risk of high blood pressure and cardiovascular disease, not all sodium is bad. Sodium is an essential mineral that helps regulate fluid balance, nerve function, and muscle contractions. The problem arises when individuals consume too much sodium from processed foods, which are often high in added salt.
Ultrahuman’s Evidence-Based Take: Focus on the quality of the salt you consume. Unrefined salts like Himalayan pink salt or sea salt contain additional minerals and are less processed. Also, focus on whole, fresh foods and limit the intake of processed and packaged foods that are typically high in sodium.
Why It Matters:
Moderate salt intake is necessary for proper bodily function. Rather than eliminating salt entirely, aim for a balanced approach and reduce your intake of highly processed, sodium-rich foods.
8. Myth: Eating Late at Night Causes Weight Gain
Busted: The idea that eating after a certain hour leads to weight gain is based on a misunderstanding of how the body processes food. What matters most is the total calorie intake over the course of the day, not the timing of meals. That being said, eating large, heavy meals right before bed can interfere with digestion and sleep quality, but a small, healthy snack may actually promote better sleep and recovery.
Ultrahuman’s Evidence-Based Take: If you're hungry before bed, opt for a light, protein-rich snack that won’t spike your blood sugar levels. Greek yogurt, a small portion of nuts, or a protein shake can be a good choice. Consuming high-quality foods at any time of day can support muscle repair, prevent overnight catabolism, and help with fat loss.
Why It Matters:
Your body doesn’t “know” the clock, but it does know how to process nutrients. Eating balanced meals throughout the day and night is far more important than worrying about the timing of your food.
