Any time is better than never, but research suggests you can score even more blood sugar benefits by carving out time to sweat during this time of day.
Some research has found that walking after meals for just two minutes (yes, really!) can have a substantial impact on blood sugar. But beyond sprinkling in little activity "nuggets" after a meal, researchers are still on a quest to learn more about the best methods, times of day and intensity levels of exercise that might affect - and potentially help us better manage - our blood sugar levels.
Blood sugar levels naturally rise and fall throughout the
day, but when your body has trouble regulating this process, it can lead to
insulin resistance and other health issues. Typically, your body uses
insulin to help cells absorb glucose from your blood. When this process works
well, blood sugar levels remain in a healthy range, providing steady energy
throughout the day. However, for people with insulin resistance, such as those
with type 2 diabetes, glucose stays in the bloodstream, leading to higher blood
sugar levels.
Fortunately, regular physical activity is one of the best
ways to keep your blood sugar levels in check because glucose is drawn into
your muscle cells for fuel during physical activity. Studies indicate that this
process helps lower blood sugar levels by improving insulin sensitivity and
increasing glucose absorption by cells, even after the workout is finished. Regular
exercise can also improve cardiovascular health, which is closely linked to
better blood sugar control. Research suggests that the timing of your
workout could make a real difference in how well your body manages glucose,
too.
Afternoon and evening exercise seem to offer the most
benefit for blood sugar control. While morning exercise is still beneficial,
studies suggest that exercising later in the day may help you better manage
insulin resistance. However, the most important thing is to find a time
that works for you and stick to a consistent routine.
A 2022 study published in Diabetologia found that
participants who exercised in the afternoon experienced an 18% reduction in
insulin resistance, while those who worked out in the evening saw a 25%
decrease. On the other hand, morning exercise or spreading activity
throughout the day didn’t show significant improvements in insulin resistance
or liver fat content. While the reasons for this are still being studied, it
suggests that afternoon and evening workouts may offer the best benefits for
managing blood sugar levels.
How Much Exercise Do You Need?
The Centers for Disease Control and Prevention (CDC)
recommends that healthy adults aim for 150 to 300 minutes of moderate-intensity
or 75 to 150 minutes of vigorous-intensity physical activity each week. However,
even small amounts of physical activity can make a difference. If you’re new to
exercise, start slow and gradually increase your activity level as you build
endurance.
Types of Exercise That Support Healthy Blood Sugar
To make the most of your exercise routine for blood sugar
regulation, it helps to incorporate a variety of activities. Here are some
types of exercise to consider:
Aerobic Exercise: Activities like walking, swimming,
cycling and running are excellent for improving heart health and lowering blood
sugar. Regular aerobic exercise can enhance blood flow, reduce insulin
resistance, and support long-term weight management.
Strength Training: Research shows that lifting weights
or using resistance bands helps build muscle mass, which can increase glucose
uptake by cells and improve overall insulin sensitivity. Aim to
incorporate strength training exercises at least two to three times a week.
Yoga and Stretching: Yoga can help reduce stress and promote relaxation, which can help lower cortisol (a stress hormone) and balance blood sugar levels. Incorporating stretching and mindfulness practices can also support better glucose control.
The Bottom Line
Research shows that afternoon and evening exercise might
provide the biggest benefits to blood sugar control. While this is interesting
to keep in mind, it's vital to note that physical activity at ANY time of day
is beneficial. In fact, morning
exercise might actually be your best option if you find it challenging
to make exercise a part of your daily routine. (Translation: Early birds, keep
up the great work if you're loving that 6 a.m. yoga class or walk!)
Keep in mind that exercise is just one of many healthy
ways to lower your blood sugar. Sleep, hormones, medicine and other sneaky
factors can impact blood sugar as well. What's on our plate makes the
biggest impact, of course, so keep eating diabetes-friendly meals!
