Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Intermittent carbohydrate restriction

Four weeks of intermittent carbohydrate restriction: a dietary regime alternating between two days of restricting carbohydrate intake to 70-90 grams, while energy intake is ad libitum, from fat- and protein-containing foods, and two days of non-restricted diet.
