Why do some people seem to build muscle effortlessly while others struggle to lose body fat despite putting in the same amount of work? Fitness instructor Eugene Pallisco says genetics certainly play a role, but they don't have the final say.
By understanding how genetics, nutrition, and exercise work together, you can focus on the factors that have the greatest influence on building a lean, strong, and healthy physique.
Genetics Sets the Blueprint
If you've ever wondered why one person builds muscle more easily while another struggles to lose body fat despite similar effort, genetics are part of the explanation. Your DNA influences bone structure, muscle fiber composition, hormone levels, metabolism, and where your body naturally stores fat. These inherited traits affect how your body responds to training and nutrition.
Genetics also influence appearance even when two people have similar body fat levels. Some naturally have broader shoulders, narrower waists, longer limbs, or muscles that appear fuller because of their attachment points. As a result, two equally fit people can look very different.
However, genetics are only the blueprint, not the finished product. Daily habits ultimately determine how much of your physical potential you achieve.
"You can't choose your genetics, but you can absolutely choose the habits that shape your health every day," says Pallisco. "Consistency will always outperform perfection."
While your genes cannot be changed, your body composition, strength, endurance, and overall fitness can improve dramatically through regular exercise, quality nutrition, adequate sleep, and proper recovery.
Eugene Pallisco on How Nutrition Influences How Lean You Become
Although genetics influence where fat is stored, nutrition largely determines how much body fat you carry. That's why people with similar genetics can look very different depending on their eating habits.
Reducing body fat enough to reveal muscle definition depends primarily on maintaining an appropriate calorie intake while consuming sufficient protein, vitamins, minerals, and other essential nutrients.
Protein supports muscle repair and growth after exercise, while fiber-rich whole foods help improve satiety and make healthy eating easier to sustain.
Eugene Pallisco explained that even with all the research we have, many people still believe they can out-exercise a poor diet. “A workout may burn several hundred calories, yet those calories can be replaced quickly through food or drinks. Nutrition and exercise complement one another, but nutrition has the greater influence on body fat levels,” he emphasized.
Sustainable eating habits maintained over months and years are far more effective than restrictive diets that are difficult to maintain.
Exercise Shapes the Physique Beneath the Body Fat
Nutrition may determine how lean you become, but exercise determines the shape, strength, and function of your body.
Resistance training stimulates muscle growth and maintenance, while cardiovascular exercise improves heart health, endurance, and contributes to overall energy expenditure.
As muscles are challenged, they repair and become stronger. Over time this leads to firmer arms, stronger legs, improved posture, and a more athletic appearance. Exercise also enhances mobility, balance, coordination, and bone health, providing benefits that extend well beyond aesthetics.
Fortunately, building a strong physique does not require spending hours in the gym every day. A balanced program that combines strength training, cardiovascular exercise, and adequate recovery is sufficient for most people to make steady progress.
"The best workout is the one you can keep doing consistently," Pallisco says. "Small improvements repeated week after week lead to remarkable long-term results."
Rather than searching for the perfect routine, focus on building habits that fit your lifestyle and can be maintained over time.
You Can't Change Your Genetics, But You Can Maximize Your Potential
Some people naturally gain muscle faster or stay lean more easily, but genetics don't prevent someone from becoming significantly healthier and stronger.
Research consistently shows that individuals respond differently to exercise. Some experience rapid gains in strength or endurance, while others progress more gradually. Even so, nearly everyone benefits from regular physical activity and good nutrition. The difference is usually the rate of progress rather than the ability to improve.
Comparing yourself to people with different genetics can therefore be misleading, particularly on social media, where exceptional genetics, years of disciplined training, and sometimes performance-enhancing substances can create unrealistic expectations.
A more productive approach is to focus on your own progress. Prioritize consistent training, balanced nutrition, quality sleep, and recovery while measuring success against where you started rather than against someone else.
Whether your goal is a flatter stomach, stronger legs, more defined arms, or better overall health, those improvements are within your control, no matter where you started.
