Energy balance

In patients with type 2 diabetes, adopting any healthy dietary pattern (Mediterranean, low-carb, plant-based, etc.) significantly improves body weight and glycemic control (HbA1c) compared to usual diet within the first six months, though these benefits attenuate and lose statistical significance after 12 months.

If you have Type 2 Diabetes, changing your diet to a healthier pattern (like Mediterranean, low-carb, or plant-based) will help you lose weight and lower your blood sugar significantly within the first 6 months compared to doing nothing. However, these benefits tend to fade after a year if adherence drops. There is no single 'best' diet; choose the one you can stick to long-term, as consistency matters more than the specific macronutrient split.

GoodSupportsHIGH confidence
In patients with type 2 diabetes, all dietary patterns outperformed usual diet in improving body weight and HbA1c after 6 months... These effects were attenuated and not statistically significant after 12 months.
