Clinical Trial Summary

The purpose of this study is to establish safety of biweekly intermittent fasting in the setting of type 2 diabetes mellitus or prediabetes under treatment with non-hypoglycemic agents (e.g. metformin).

Description:

This study is proposed as a prospective interventional cohort safety study for biweekly intermittent fasting. In the effort to improve compliance of lifetime dietary change, the version of 5:2 intermittent fasting to be applied in this study will be somewhat less intensive than implemented then what has been proposed in some recent, similar studies. On fasting days, instead of limiting the subject to a specific calorie count, the subject will be instead instructed to skip either the first or last meal of the day in order to complete a 12 to 16 hour fast, during which time they are allowed drink water or any non-caloric beverage of their choice, but not consume any calories. Furthermore, the patient will be instructed for their remaining 2 meals to consume no more than they would on a normal, non-fasting day.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of hypoglycemic events	This study's intent is to investigate the safety of this intervention for use in a broader scope. It is imperative that risks are known for each subpopulation of diabetics. To this point, our literature review indicates that hypoglycemic events did occur at higher rates in fasting populations taking hypoglycemic medications. We intend to look at rates of hypoglycemia on those not on hypoglycemic medications to assess if this trend continues.	Number will vary depending on the number of hypoglycaemic events per each subject and will be recorded throughout study until completion at 12 weeks
