When Should You Eat Before or After Exercise?

Written by Dr. Ambrish Mithal, Chairman and Head, Endocrinology and Diabetes, Max Healthcare

In the journey of managing blood sugar levels, the interplay between exercise, eating habits, and medication is paramount. Dr. Ambrish Mithal, an esteemed expert in endocrinology and diabetes, emphasizes the importance of this balance. Let’s delve into the question many of us ponder: should we eat before or after exercise? And what considerations should those managing diabetes keep in mind?

Pre-Exercise Management

Embarking on a new fitness regimen requires thoughtful consideration, especially for individuals with specific health conditions like Type 1 diabetes, the elderly, or those with heart disease. Dr. Mithal advises against sudden starts and advocates for a gradual increase in exercise levels.

For those managing Type 2 diabetes without medication, there’s often no need to check blood sugar levels before exercise. However, for individuals on insulin or other medications that lower blood sugar, a pre-exercise blood sugar test is recommended. If levels are below 100 mg/dl, a snack containing 15-30 grams of carbohydrates can help stabilize blood sugar. Conversely, if levels exceed 300 mg/dl, exercising may not be safe, particularly for those on insulin.

Dr. Mithal suggests waiting at least an hour after a meal before exercising to ensure blood sugar levels are within a safe range. This timing allows the body to utilize fat stores efficiently for energy.

During Exercise: Watch Out for Low Blood Sugar

During exercise, the risk of hypoglycemia (low blood sugar) is heightened, particularly for individuals on insulin or medication. While continuous blood sugar monitoring every 30 minutes during exercise is ideal, it may not always be practical. However, individuals with well or moderately-controlled Type 2 diabetes who take certain medications, such as Metformin or DPP4 inhibitors, generally face fewer risks during exercise.

Conclusion

Balancing exercise and nutrition is a crucial aspect of managing diabetes. Dr. Mithal’s insights shed light on the importance of timing meals and monitoring blood sugar levels, especially before and during exercise. By understanding these nuances and consulting with healthcare professionals, individuals can navigate their fitness routines while effectively managing their diabetes. Remember, it’s not just about when you eat, but how you manage your overall lifestyle that contributes to better blood sugar control.
