Rule of 15: Treat Lows, Don’t Overdo It

When you feel a low, take 15 grams of fast‑acting carbohydrate—simple sugar that absorbs quickly.

  • Step 1: Consume 15 g fast‑acting carbs.
  • Avoid overeating: stick to 15 g. Skip foods high in fat or protein—they slow sugar absorption.
  • Recheck in ~15 minutes. If still low, take another 15 g and recheck.
  • Why it works: following this rule helps stabilize levels and prevents rebound highs and lows.
Smart 15 g options: 3–4 glucose tablets (check the label), 1 tube glucose gel (15 g), or 4 oz (120 mL) juice/regular soda. You shouldn’t use chocolate or nut bars—they’re high in fat and take longer to absorb.
