People without diabetes can rely on their pancreas and liver to control their blood glucose levels, meaning you don’t need to go on a walk after eating carbohydrates to lower your glucose levels.

“It’s become increasingly trendy for non-diabetics to use glucose monitors during exercise as a way to further enhance performance and optimise sports nutrition and fueling strategies, but this is a very new and upcoming area and definitely not essential for health at all,” says Gelbke.

However, if you feel like your blood sugar may be on the low side – feeling dizzy, shaky, hungry or tired - it’s probably a good idea to eat before exercising. And if you’re worried about your blood sugar, talk to your doctor about it; they’ll be able to do a series of quick tests that’ll see whether your levels are within the healthy range both fasted and after eating. For the majority of healthy people, however, fueling well around your training and doing regular exercise is probably all you need to worry about.
