The Metabolic Impact of Intermittent Carbohydrate Restriction in Individuals With Type 2 Diabetes

Summary

The primary aim of this randomized cross-over intervention study is to investigate the effect of four weeks of intermittent carbohydrate restriction (alternating between two days of normal dietary intake and two days of carbohydrate restriction to 70-90 grams) on 24-hour average sensor glucose in individuals with type 2 diabetes compared with a four-week control period with normal dietary intake.
