请将下面这段英文改写成口语化的表达。原文为： "The primary reason why a low-carb diet may have negative effects on exercise performance is due to the depletion of glycogen stores in the muscles and liver, which regulates the body's blood sugar levels, thereby affecting overall energy output. The body relies on these glycogen stores to provide a quick and readily available source of energy, especially during high-intensity exercise. Decreased glycogen stores can result in fatigue, decreased performance, and reduced endurance."

(low-carb)低碳水饮食可能对运动表现产生负面影响，主要是因为身体的肌肉和肝脏里的糖原储备减少了。这些糖原储备对调节我们身体的血糖水平很重要，也直接影响我们总体的能量输出。身体需要这些糖原来提供快速且方便的能量，尤其是在高强度运动时。如果糖原少了，就可能导致疲劳、表现下降和耐力下降。总而言之，低碳水饮食可能让你在运动时感到力不从心。
