11 Personalized Nutrition Tips Based on Your Body's Unique Needs (Beyond Fad Diets)

2. Track Your Energy, Not Just Calories

Calorie counting doesn’t tell you if a meal worked for you. What matters more is how you feel—physically and mentally—after eating. Keep a simple energy and focus tracker for a week. Log what you eat, when you eat, and how you feel two hours later: sleepy? Sharp? Craving more? This helps identify what fuels your body vs. what fogs it. You’ll begin to see that portion size is only one part of the equation—timing, nutrient density, and food combinations play a massive role. Personalized nutrition isn’t just about quantity; it’s about how food functions in your body.
