Generic - Fasting: Hours Without Eating (1 hour)

If you mean a drop in glucose during fasting, shorten the fasting window and avoid fasting when you are ill, dehydrated, exercising heavily, or drinking alcohol.

Break a fast gradually with a small balanced meal such as plain Greek yogurt with berries and chia seeds, rather than a large high-sugar meal.

Include protein and fat at the first meal—such as eggs, tofu, fish, nuts, or avocado—to slow absorption and reduce rapid swings.

Choose slower-digesting carbohydrates in modest portions, such as lentils, chickpeas, beans, steel-cut oats, quinoa, or non-starchy vegetables.

Drink water and consider an electrolyte drink without added sugar if dehydration may be contributing to symptoms.

If you have shakiness, confusion, sweating, faintness, or a measured low reading, treat it promptly with a fast-acting carbohydrate and seek medical advice—especially if episodes recur or you use diabetes medication.
