Long-Term Low-Carb Diets Effective for Dyslipidemia, Not Glycemic Control in Type 2 Diabetes: Study
In a recent study, researchers indicated that long-term low-carbohydrate diets (LCD) in people with type 2 diabetes had significant improvements in some lipid parameters but did not have substantial additional benefits for glycemic control. The conclusion was drawn from the overall analysis across RCTs of the effects of LCD on the glycemic management and other metabolic risk markers in diabetic adults for a period of more than 12 months. The research was published in the Journal of Diabetes Investigation by Takahiro Ichikawa and colleagues.
The efficacy of long-term LCD in the management of type 2 diabetes is arguable. In spite of many trials in this respect, controversy still persists regarding the influence of such diets on glycemic control. Thus, the present meta-analysis sought to resolve this issue through data synthesis from multiple RCTs on long-term effects of LCD on glycemic control and other health outcomes.
A PubMed, Embase, and Cochrane Database search up to June 2023 for the identification of articles was undertaken. The inclusion criteria were RCTs of LCD interventions that had been conducted in people with T2D and having an intervention period of >12 months. Primary outcome: Change in HbA1c (long-term LCD vs control). Secondary outcomes were changes in SBP, DBP, LDL-C, HDL-C, TGs, and body weight.
