Walking in Heat and Blood Glucose

Answered on August 19, 2014

I'm thin very low carb paleo. I've noticed that after I do my daily walk (90 minutes) in the hot weather (85 to 90 plus degrees), my blood glucose tests 10 to 15 points higher. I am not a diabetic and test myself postprandially to make sure my fasting is in the 80s and that post-prandially I never get above 120 -- usually my highest is about 110 if I've eaten a large meal.

Ifyou're walking within 3 hours of waing, the most likely explanation is a liver dump. Otherwise, unless you're walking real strenuously, those 90 minutes ... which is very long, though ... shoudln't raise your BG much, not via cortisol. The BG pattern is lowest BG ater 30 mins., slightly elevated but still lower than b4 exercise, after 60 mins., and slight elevation if any after 90.

SUMMER time and vitamin D, should make you more insulin sensitive...IME, you also handle fruit better when youve gotten good sun

I usually walk the same amount of time in temperatures about 10 degrees higher and notice a slight increase too. The highest readings I ever get are not after eating but after a bout of high intensity exercise. Yesterday I got a reading of 124 (highest in 2 weeks) after 5X 30sec shoulder press, 30sec rest, 30sec KB swings, 30sec rest, 30sec calorie row, 1 minute rest. As I understand it, cortisol raises blood glucose levels. I also wonder about the effect dehydration over a 90 minute walk which would also raise cortisol.

It's interesting that your levels are so low. I've noticed that low carb Paleo has raised my fasting levels. The phenomenon is explained at Hyperlipid http://high-fat-nutrition.blogspot.com/2007/10/physiological-insulin-resistance.html

When does your daily walk take place? In the morning upon rising, midafternoon, or before going to sleep?
