Various dietary factors can influence workout performance, including macronutrient balance, meal timing, and hydration. Consuming the right amount of carbohydrates before a workout can provide necessary energy, while protein helps with muscle repair. Eating a meal rich in carbs and protein about 2-3 hours before exercising optimizes performance. Staying well-hydrated is equally important, as even mild dehydration can impair endurance and strength. Additionally, specific micronutrients such as iron and calcium can affect energy levels and overall muscle function, playing critical roles in enhancing athletic performance.
