The right pre-exercise snack can give you the fuel you need to power through your workout.
Staying active is a great way to naturally lower your blood glucose levels. However, when you have diabetes, sometimes exercise can lower your blood sugar too much. That's why finding diabetes-friendly snacks for your pre-workout is so important. Fueling your body with the right foods before exercise can provide busy muscles with the energy they need, while additionally protecting them against dangerous lows.
Just like carbohydrate needs vary substantially among people with diabetes, so do snacking requirements for exercise. Here are some special considerations to keep in mind before hitting the gym or pavement.
One Size Doesn't Fit All
Your snacking needs before exercise depend on many factors, such as your blood glucose level, your medication regimen, and how long and hard you work out. For example, if you don't require medication for blood sugar management or you have ample blood glucose, it's unlikely you'll need a snack at all. On the flip side, if your blood sugar has been known to drop rapidly or you take insulin or medication such as glyburide, glimepiride, or glipizide, a snack may be critical for preventing dangerous lows.
Know Your Numbers
Before grabbing a snack, the first thing you'll want to do is check your blood glucose level. Knowing your blood sugar is the very best way to match the snack to your nutrient needs and workout routine. Suppose that you're going for a quick bike ride. In that case, you may only need a few carbohydrates for fuel. Working out longer? You may require more carbs and possibly even some protein to slow down carbohydrate digestion.
If you have type 2 diabetes, these guidelines can help you determine the best snack based on your glucose levels and exercise regimen for optimal blood sugar management:

When planning snacks and workouts, keep in mind that these guidelines aren't a substitute for professional advice. Whether you're a novice at exercising or an avid marathon runner, be sure to speak about diabetes-friendly snacks for your pre-workout with your doctor or diabetes educator to develop a plan that's right for your unique needs.
