What Is the Crash-and-Crave Cycle?

Keyword Focus:

• crash and crave cycle

• why do I feel hungry after eating sugar

• reactive hypoglycemia and cravings

1. High Blood Sugar and Insulin Surges

Consuming sugary foods or refined carbs causes a rapid spike in blood glucose. In response, your body releases a surge of insulin to move sugar from your bloodstream into your cells.
Example: Eating a muffin or drinking a soda can raise your blood sugar from 90 mg/dL to 180 mg/dL in just 30 minutes—setting the stage for a crash.

2. Reactive Hypoglycemia: The Sugar Crash

When insulin overshoots, your blood sugar can plummet below normal (sometimes as low as 60 mg/dL).
Symptoms of a blood sugar crash:

• Irritability

• Shakiness

• Brain fog

• Intense cravings for quick energy (especially sweets or carbs)

This is common in people with prediabetes or insulin resistance, where the body overreacts to sugar, causing dangerous swings that stress the pancreas and disrupt appetite hormones.

3. Brain Panic Mode: Why Am I Hungry After Eating?

Your brain depends on glucose for energy. When blood sugar drops suddenly, your brain interprets it as starvation, activating hunger hormones like ghrelin.
Result: You feel hungry again—often just an hour after eating a high-sugar meal.
