What is a potential consequence of low carbohydrate intake?

Low carbohydrate intake can lead to fatigue and decreased exercise performance because carbohydrates are the primary source of energy for the body, especially during high-intensity activities. When carbohydrate intake is insufficient, the body's glycogen stores—a crucial source of readily available energy—become depleted. This can result in feeling tired or lethargic, as the muscles are not receiving the necessary fuel to function optimally during exercise.

In addition to fatigue, low carbohydrate consumption can hamper performance in workouts, making it challenging to maintain endurance and exertion levels. Muscles rely on carbohydrates for quick energy, and without adequate intake, a person may feel weaker and less capable of sustaining prolonged exercise sessions. This inadequate energy availability also affects recovery, leading to a cycle of fatigue and poor physical performance.

Other options, such as increased energy levels or weight gain, do not accurately represent the effects of low carbohydrate intake. Instead, lower energy levels and diminished capacity for effective exercise performance are likely outcomes, reinforcing that the body needs adequate carbohydrates for optimal function and stamina during physical activity.
