The primary aim of this pilot study is to test whether low-carbohydrate diet (LCD) instituted in children/adolescents with type 1 diabetes (T1D) can improve their disease control. The primary objective of the trial is the change in continuous glucose monitoring time in target range 3.9-10.0 mmol/l (TIR) in a 5-week period on LCD as opposed to a 5-week period on recommended carbohydrate diet (RCD).

Secondary objectives are:

Changes in immune parameters during the LCD period; Differences in fecal microbiome during the LCD period; Differences in fecal, serum and urine metabolome during the LCD period;
