[QUOTE="TorqPenderloin, post: 1424050, member: 211504"] I'm not saying you should avoid food entirely. I'm saying that you should avoid over-complicating the situation as much as possible. When you combine insulin, carbs, and exercise together you create a very complicated equation. I eat roughly 3000 calories a day, but only about 5 (coffee) come before my workouts in the morning. To answer your question, I correct for anything below 3.7 mmol/l. However, there is much more to the equation than that. My basal insulin (Tresiba) is set perfectly meaning that in most cases I can fast for 8-10 hours and my blood sugar will not rise or drop more than .5 mmol/l in that time. Consequently, I can go for a 90 minute run starting at 4.0 mmol/l and not have to worry about my blood sugar dropping. However, this assumes I haven't injected any bolus insulin with the last 4 hours. However, if I have recently eaten and injected insulin I would probably not start a run at anything less than 5 mmol/l and I'd certainly be very careful. With bolus insulin on board, an evening walk could easily cause hypoglycemia. For me, the problem is that a 1u correction dose will normally drop me about 1.7 mmol/l. If I factor in exercise, 1u could drop me more than 3 mmol/l. Ultimately, my point is to say that it's not the number I start at that's most important before exercise. It's the circumstances leading up to exercise that I most consider: how much bolus insulin do I have on board? How many carbs did I just eat? High/Low GI carbs? Did I also eat a lot of fat? What kind of exercise am I engaging in? For how long? Bottom line- if I haven't recently injected insulin the equation is very simple. [/QUOTE]
