Fitness Diet Selection


Both diet and exercise hold equal importance for our well-being, and they are indispensable when it comes to body management. In addition to the three regular meals throughout the day, particular attention should be given to our diet before and after workouts. Today, we will discuss what to eat before and after engaging in physical fitness activities.


Our dietary choices before and after exercise significantly impact our athletic performance and post-workout recovery. We need to ensure an adequate energy supply during the workout and facilitate muscle tissue repair and glycogen replenishment afterward. Our dietary plan should be analyzed based on the type and intensity of the exercise. Continue reading for more insights.


The body’s energy systems can be categorized into three primary categories:

1. ATP/CP (Adenosine Triphosphate and Creatine Phosphate System)
This system supports short but highly efficient bursts of energy. It utilizes creatine phosphate as an energy source, which is rapid but has a brief duration, lasting approximately 10 seconds.

2. Glycolytic System (Anaerobic System)
The second system is the glycolytic system, where the body breaks down carbohydrates in anaerobic conditions to generate energy. However, this process results in the production of lactic acid, which contributes to muscle soreness. Its effective usage time is around 2 minutes.

3. Aerobic System
The third system is the aerobic system, where the body metabolizes carbohydrates, proteins, and fats to produce energy. Although slower, it can provide energy to the body for an extended period.


During high-intensity exercises like weightlifting, sprinting, and most resistance training, the body primarily relies on the first two anaerobic systems for energy provision. Conversely, during low-intensity activities such as walking, jogging, swimming, and cycling, which require sustained energy supply, the aerobic system plays a crucial role.
