Macro partitioning

Low-carbohydrate diets are effective for short-term glycemic control (3-6 months) in type 2 diabetes, reducing HbA1c more than higher-carbohydrate diets, but this benefit is not maintained at 12 months.

If you have type 2 diabetes, reducing carbohydrates can help lower your blood sugar levels in the first few months. However, this effect tends to fade after a year, so it is not a permanent fix on its own. It is best used as part of a broader strategy that includes weight management and food quality.

It concluded that lower carbohydrate diets were effective for glycaemic control in type 2 diabetes compared with higher carbohydrate diets, with a greater reduction in HbA1c (weighted mean difference –4.7 mmol/mol [–0.47%]) in the short term (3–6 months), but this benefit was not maintained at 12 months [39].
