A glucose (or blood sugar) spike occurs when you consume simple sugars or refined carbs that enter your bloodstream all at once. Your body is flooded with more energy than it can use immediately, leading to:
The "Crash": A rapid drop that leaves you feeling tired and sluggish.
The "Fog": Difficulty concentrating and increased irritability.
Long-term Stress: Frequent spikes can lead to inflammation and metabolic issues over time.
