A 45-day VLCKD significantly improves metabolic parameters (weight, BMI, blood pressure, lipids, insulin resistance) regardless of protein source, but animal protein may negatively impact renal markers.
A strict 780-calorie ketogenic diet for 45 days will significantly improve your weight, blood pressure, and blood sugar/insulin levels, regardless of whether you use whey, vegetable, or animal protein. However, if you have kidney concerns, be cautious with animal protein sources as they may slightly worsen renal markers in this context.
VLCKDs led to significant weight loss and a striking improvement in metabolic parameters over a 45-day period... The markers of renal function worsened slightly in the animal protein group.
Why this rating
Randomized pilot study, small sample size.
