Fasting Fatigue? How Data-Driven Insights Can Keep You Energized

"I feel great!" ... "I feel dizzy."

Fasting is often a rollercoaster. One day you have mental clarity; the next, you need three naps. Many people quit because they assume the fatigue is part of the process.

It isn't. It's usually a data error.

The Electrolyte Equation

The #1 cause of fasting fatigue isn't lack of food; it's lack of sodium, potassium, and magnesium.

When insulin drops (during fasting), your kidneys dump water and electrolytes. If you don't replenish them, you get the "Keto Flu."

Smart tracking apps monitor this hidden metric. If you log 20 hours of fasting but zero sodium intake, an AI assistant can flag it: "Energy warning: You are likely low on electrolytes. Drink salt water."

The Cycle Sync (For Women)

Hormones play a massive role here. For women, fasting during the luteal phase (the week before a period) is biologically harder and often leads to extreme fatigue due to progesterone demands.

Context-aware AI can track your cycle and suggest: "High hormone phase detected. Let's reduce fasting window to 12 hours and increase complex carbs."

Pushing through fatigue isn't toughness; it's inefficiency. Listen to the data.
