A low-GI diet preserves renal function (eGFR) better than a whole-grain wheat-fiber diet in patients with type 2 diabetes over 3 years.
If you have type 2 diabetes, a low-GI diet may offer better protection for your kidneys than a standard high-wheat-fiber diet. While both diets are healthy, the low-GI approach helped maintain kidney function (eGFR) better than the wheat-fiber diet, which showed a slight decline in kidney function over 3 years.
GoodSupportsHIGH confidence
The low-GI diet resulted in preservation of renal function, as estimated glomerular filtration rate, compared with the reduction following the wheat-fiber diet.
Why this rating
RCT, 3-year duration, clear statistical difference in secondary outcome.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
