Message: <blockquote data-quote="Deleted member 527103" data-source="post: 2674155">I would say "this depends". It depends - how many carbs are included in your snack. I would not eat a doughnut and then exercise assuming the exercise would burne the carbs- how intensive your exercise is. This is a very person thing. For some it maybe a gentle stroll. For me, it would need to be a 30+ minute spin class or equivalent. - what type of exercise you are doing. Resistance training will raise BG so not ideal to snack without insulin beforehand. I often have to take extra insulin before climbing without food. - what your BG is when you snack. If our BG is too high when we start to exercise, it could be a strain on our bodies which will push levels higher. What is "too high"? For me it is anything over 9 mmol/l but I know some people start their Parkrun at 13 mmol/l. I try to avoid eating (and exercise) when my BG is in double figures as I know I am insulin resistant.</blockquote>
