Best Snacks for Low Blood Sugar Under 100 mg/dL Before Exercise

If your blood sugar dips below 100 mg/dL before exercise, a quick 15-30g carb snack prevents hypoglycemia while fueling safe activity for diabetics. Retest after 15 minutes to confirm levels above 100-126 mg/dL before starting.

Fast-Acting Carb Options (15g Carbs)

Consume these for rapid glucose rise without fiber delay.

• 4-6 oz fruit juice, regular soda, or glucose tablets/gel (4 tabs).

• Half banana, 15 grapes, or 1 tbsp honey/raisins.

• Small apple (4 oz) or 2 tbsp dried fruit.

Balanced Snacks with Protein (15-25g Carbs)

Add protein/fat for sustained energy during workouts over 30 minutes.

• Apple slices with 1 tbsp peanut/almond butter.

• ⅔ cup plain Greek yogurt with berries.

• 4-6 whole grain crackers with cheese or 15 almonds.

• Slice of whole wheat bread with 1 tbsp nut butter.

Indian-Friendly Choices

• Small besan chilla (gram flour pancake) or banana with handful peanuts.

• Half roti with curd or a few dates with almonds.

Eat 10-30 minutes prior; adjust based on workout length—more carbs for longer sessions. Avoid high-fat foods that slow absorption.
