The Effect of Whey Protein Consumption on Hypoglycemia in Adults with Type 1 Diabetes During Fasting Ramadan.

Patients with type1 diabetes who intend to fast will be supplied with dietary supplement "Whey protein" to be taken with Suhoor (predawn meal) for one week during Ramadan. They will be then crossed over to not taking the whey protein for another week. the order of taking whey protein will be randomized.

During both weeks patients will be monitored through flash continuous glucose monitoring and data will be compared in regards to incidence and timing of hypoglycemia, hyperglycemia, and time in target range.

After Ramadan data will be collected on number of days they had to brake fast due to low blood sugar during both weeks and overall satisfaction with using whey protein during Ramadan.
