Welcome to icliniq.com.
The patients with type 1 diabetes are advised not to fast. However, if you are healthy and having a good blood sugar control, then you can reverse the dose of insulin as in, take the night dose in the morning and morning dose at night and fast.
Be prepared for breaking your fast if your sugar falls below 70 mg/dL or above 300 mg/dL. No need for vigorous exercise.
Hope you find my advice beneficial.
