Concurrent low-carbohydrate, high-fat diet with/without physical activity does not improve glycaemic control in type 2 diabetics

| Summary: | Aim: This study aimed to determine if a low-carbohydrate, high-fat diet (LCHFD) provides any benefits of glycaemic control in patients with type 2 diabetes mellitus, either alone or in conjunction with physical activity. Methods: Type 2 diabetics (n = 39) were assigned into either a concurrent physical activity and LCHFD group (DiExG), LCHFD only group (DietG) or control group (ConG). Results: No significant (p > 0.05) changes were observed in glycated haemoglobin (HbA1c), glucose and insulin in either the DiExG (HbA1c: p = 0.592; 8.3% decrease, glucose: p = 0.477; 11.1% decrease and insulin: p = 0.367; 44.1% increase) or DietG (HbA1c: p = 0.822; 0% change, glucose: p = 0.108; 11.0% decrease and insulin: p = 0.976; 4.2% decrease) group. Conclusions: In this study, neither an LCHFD alone nor in combination with a physical activity programme succeeded in eliciting improvements in insulin sensitivity in the type 2 diabetics. As such, adoption of a LCHFD, either alone or in combination with physical activity, should not unequivocally be part of the treatment approach for type 2 diabetics. Furthermore, it should carefully be weighed against the benefits of more balanced dietary and/or physical activity interventions. |
