Consensus guidelines: CHO intake before, during and after exercise.

	Insulin Condition
	low	high
At exercise onset based on BG
<90 mg/dl	15 g	25 g
90–124 mg/dl	10 g	10 g
>124 mg/dl	—	—
During exercise based on duration
≤30 min	—	15–30 g
30–60 min	10–15 g/h	30–60 g/h
> 60 min	30–60 g/h	up to 75 g/h
At end of exercise based on BG
<90 mg/dl	20 g	20 g
≥90 mg/dl	—	—

If BG is <90 mg/dl at exercise onset, exercise is delayed until BG>90 mg/dl. During exercise of more than 60 min under high insulin conditions, we consider CHO intake of 60–70 g/h.
