Plant-heavy diets beat keto for kidney and weight health

Plant Based Diet
If you're growing vegetables, legumes, and whole grains in your own backyard, this review is a reminder that filling your plate from that garden does more than taste good, it may protect kidney function while helping shed excess weight.
Doctors compared three popular ways of eating, the Mediterranean diet, diets built mostly around plants, and low-carb or keto diets, to see which works best for people who are overweight and also have kidney disease. Plant-rich and Mediterranean-style eating came out ahead: they support healthy weight loss, calm inflammation, and seem gentler on the kidneys over time. Keto and very low-carb diets dropped weight fast but carried more risk of kidney stones and acid buildup, making them a less certain long-term choice.
Key Findings
Mediterranean and plant-dominant diets were linked to improved insulin sensitivity, reduced dietary acid load, and anti-inflammatory effects in people with obesity and chronic kidney disease.
Plant-forward eating patterns showed potential to improve gut microbiota composition and reduce production of uremic toxins, plus possible slowing of kidney function decline.
Low-carbohydrate and ketogenic diets produced faster short-term weight loss and glycemic improvement but raised concerns about metabolic acidosis, kidney stone risk, and unclear long-term safety.

A review of diet research finds that Mediterranean and plant-heavy eating patterns are safer and more effective than low-carb or keto diets for people managing both obesity and chronic kidney disease, offering steady benefits without the acid-load and kidney-stone risks tied to strict carb restriction.

Dietary Patterns for Obesity in CKD: Mediterranean, Low-Carbohydrate, and Plant-Forward Approaches-What Fits Best?
Obesity and chronic kidney disease (CKD) frequently coexist and mutually exacerbate metabolic, inflammatory, and hemodynamic disturbances that accelerate kidney function decline. Dietary therapy is...

Food forests are multi-layered agroforestry systems that mimic natural forest structure by combining trees, shrubs, and understory plants to produce diverse edible and useful yields. This approach interests plant scientists because it reveals how species with different growth habits, root depths,
