    Default Exercise Timing Matters for Diabetes

    Beth Levine
    11/12/2016

    There have been lots of conflicting reports about what’s the optimum time of day to work out. Some say it’s ideal first thing in the morning to get your system revved up for the day, while others are proponents of exercising during the afternoon when body temperature is higher. For the most part, however, the essential factor is getting in your daily physical activity and doing it when it’s most convenient so that you actually stick with it. Except, it seems, if you have type 2 diabetes. New research suggests that those with this disease might benefit considerably more from doing their cardio immediately after eating.

    The study, which was conducted at the University of Otego in Dunedin, New Zealand, found that taking a walk after a meal made a greater difference in blood sugar control compared to walking at any other time of day.1

    I agree we should all exercise whenever it's convenient for us to do so. However, diabetics exercising to reduce after meal spikes in blood glucose (postprandial glycemia) should probably wait a little longer than 5 minutes after a meal to exercise, contrary to the recommendation in this article. I say this for 2 reasons: first, the after meal blood sugar levels for most people peak between 45 min. to 60 minutes after a meal. If you walk 5 minutes after a meal and only walk for 10 minutes as suggested, you miss the peak period. Naturally, the peak won't be as high but the glucose level continues to rise after your 10 min. walk. Second, glucagon--the other hormone produced by the pancreas--alerts the liver to release more glucose if it senses the body is low on glucose. Exercising triggers glucagon. If you walk 5 minutes after a meal, your glucose levels have not peaked but your body is demanding glucose to support the muscles used in walking, thus glucagon is triggered and the liver dumps more glucose into the bloodstream prematurely. By the way, walking is excellent for burning excess glucose because the largest muscles in the body--the glutes (buttocks) and the thigh muscles (quadriceps & hamstrings) burn lots of glucose...fast.

    Mr. Wizard, how does cycling compare with walking in terms of burning glucose?

    Bottom line: They are both excellent exercises for burning glucose. Obviously, there are some nuances, like walking up a steep hill will burn glucose faster than a slow paced, stationary biking position, etc. But, any exercise that directly targets the glutes & thigh muscles and causes them to work harder for an extended period of time is great for burning glucose. So, walking, cycling, swimming, stair climbing, repeated squatting up and down, etc. are all great.

    Thanks! When the days are longer, I take the cats on a walk to the pond and the 10-acre field. Now, though, after supper it's dark as a pocket, but I do have a stationery bike in the woodshed.
