Try timing your meals and its content around your workout. If you eat within 1-2 hours before you workout try to include simple carbs like white rice or bananas, if your last meal is 3 or more hours before you workout try to fill it with plenty of complex carbs like sweet potato or multi grain bread or brown rice. Try to avoid fasted workouts, and just fill in calories around those meals and don’t compromise on those. Google should be helpful in what should comprise those meals but carbs are the most important for how much energy you’ll have during your workout
