You’ve probably heard countless diet trends, myths about "good" and "bad" foods, and even old-school misconceptions like “eating 30 minutes before swimming will make you sick.” While we won’t debunk every nutrition myth in this article, we’ll cover the fundamentals—where calories come from, why proper nutrition matters, and how it fits into your training plan.
Since this is a personal training business, you might be wondering: Why spend so much time talking about nutrition? The answer is simple—nutrition is essential for progress, performance, and overall health. Let’s break it down.
Why Nutrition Matters in Your Fitness Journey
Alongside recovery, nutrition is what allows growth, strength, and endurance in your training program. It also plays a critical role in preventing long-term health issues, many of which have increased in recent years.
For those new here, I am a NASM Certified Nutrition Coach (CNC) and currently finishing my B.S. in Nutrition at Purdue University Global—so I’m more than qualified to teach you the basics of proper nutrition.
Want to gain muscle and strength? You need a caloric surplus to fuel muscle growth.
Feeling fatigued and stuck in a plateau? Training without proper nutrition will leave you exhausted and stagnant.
Overeating? Too many calories lead to excess fat gain, which can mask muscle definition and slow progress.
Understanding Calories: Energy In, Energy Out
Calories measure how much energy you get from food. Your body burns calories to fuel everything from workouts to digestion to basic survival.
Macronutrients: The Building Blocks of Nutrition
Every calorie you consume comes from one of these three macronutrients:
1️⃣ Protein (4 calories per gram) – Essential for muscle repair, growth, and recovery. Found in meat, fish, eggs, dairy, legumes, and plant-based alternatives.
2️⃣ Carbohydrates (4 calories per gram) – Your body's primary energy source. Found in fruits, vegetables, grains, and dairy.
3️⃣ Fats (9 calories per gram) – Important for hormonal balance, brain function, and long-term energy storage. Found in nuts, seeds, oils, avocados, and fatty fish.
Balancing these macronutrients properly is key to fueling your workouts and achieving your fitness goals.
Where Nutrition Fits in Your Training Plan
Your diet should support your training goals—whether it’s building muscle, losing fat, or improving endurance. Here’s how to structure your nutrition based on your fitness focus:
💪 For Strength & Muscle Gain:
Eat in a caloric surplus (more calories than you burn).
Prioritize protein intake (0.7–1g per pound of body weight).
Include healthy fats for hormone balance.
Use carbs strategically—fuel up before workouts and replenish glycogen post-training.
🔥 For Fat Loss & Weight Management:
Eat in a caloric deficit (consume fewer calories than you burn).
Keep protein high to maintain muscle mass.
Focus on whole, nutrient-dense foods to stay full longer.
Avoid liquid calories (sugary drinks, excessive alcohol).
🏃♂️ For Endurance & Performance:
Prioritize carbohydrates to fuel long training sessions.
Keep protein intake moderate for recovery.
Hydrate properly—electrolytes are key for endurance athletes.
Ensure adequate calorie intake to prevent energy crashes.
Final Thoughts
Nutrition is not about strict diets or eliminating food groups—it’s about balance, consistency, and fueling your body for success. Whether your goal is muscle gain, fat loss, or athletic performance, what you eat plays a major role in your results.
