Dietary fat influences energy levels during workouts by providing a concentrated source of calories, which the body uses for sustained energy, especially during low- to moderate-intensity exercises. Healthy fats, such as those from avocados, nuts, and olive oil, are essential for long-lasting energy as they take longer to digest, allowing the body to access fuel over time. Conversely, consuming overly saturated or trans fats may lead to sluggishness and impair performance. A balanced intake of fats contributes to optimal energy levels, helping individuals sustain their workout intensity and duration more effectively.
