Energy

When fasting deeply, energy levels can become a critical focus. In the beginning, energy might feel low as your body shifts from glucose to fat stores for fuel. This adaptation, known as ketosis, can cause sluggishness for some people, often leading them to wonder if energetic exercise is advisable. While light exercise like walking can help maintain movement and aid in fat utilization, intense workouts are best avoided until you are accustomed to fasting, as they can deplete already low glycogen stores and increase fatigue. For those well-adapted to fasting, moderate activity may actually boost mental clarity, though it’s essential to listen to your body.

Hibernating, or significantly reducing activity, can be helpful in the early stages of longer fasts when energy dips. Allowing your body to rest helps conserve energy, and focusing on calm, restorative activities can aid in adapting to this new metabolic state. Importantly, electrolyte levels play a huge role in maintaining energy and avoiding symptoms like dizziness, fatigue, and headaches. Sodium, potassium, and magnesium are particularly crucial, as they regulate muscle function, hydration, and nerve impulses. Supplementing electrolytes during deep fasts, through salt or electrolyte powders, can support steady energy levels and minimize discomfort.

Sleep also greatly influences your experience during deep fasting. Quality rest helps regulate hormones, including cortisol, which is linked to stress and energy. When sleep is poor, cortisol levels rise, potentially increasing hunger and making it harder to stick to your fasting goals. Aim for consistent, quality sleep to support your energy, mood, and physical adaptation during fasting.

To maximize your fasting experience, move gently, prioritize rest, support electrolytes, and get ample sleep. With these habits, you can enjoy more stable energy levels, reduce discomfort, and create a balanced approach that lets you reap the full benefits of fasting.
