Processed carbohydrates can lead to rapid energy spikes followed by crashes, which can impact overall energy levels. When consumed, these carbohydrates are quickly broken down into glucose, providing a short-term energy boost. However, the body then experiences a rapid drop in blood sugar, leading to fatigue and cravings for more carbohydrates. This cycle can contribute to increased fatigue and decreased overall energy stability. It is important to choose whole grains and complex carbohydrates for sustained energy.
