15‑Minute Carb Boost: Light Energy Before Your Workout

When you’re only about 15 minutes away from your workout, a small carbohydrate snack lets your muscles tap into energy quickly without that heavy, sluggish feeling.[1]

One study found that participants consuming a carb drink 30 minutes before a short, high‑intensity session extended their exercise capacity compared to other timings, with glucose and insulin stabilizing within the first 10 minutes of activity.[2]

The best moment for a light carb source is just before exercise, when you need a quick blood sugar lift without heaviness.
  1. About 15 grams of carbs in a sports drink, gel, or small fruit snack
  2. Avoid heavy foods rich in fat, fiber, or protein right before the workout

According to Mayo Clinic, if your workout is 1–3 hours after eating, a light snack can work—but if it’s less than an hour away, stick to carbs and skip heavier components.[3]
