High Protein, Low Carb Diets Greatly Improve Fertility

A diet rich in proteins appears to have a pronounced positive effect on fertility, according to new research .


Research led by Jeffrey B. Russell, MD, at the Delaware Institute for Reproductive Medicine (DIRM) showed women undergoing in vitro fertilization (IVF) treatments who consumed high levels of protein and low levels of carbohydrates had better quality eggs and embryos.

Patients whose daily protein intake was 25% or more of their diet and whose carbohydrate intake was 40% or less of their diet had four times the pregnancy rates of patients who ate less protein and more carbs daily before and during IVF cycles.

Embryo development was assessed after five days of culture or at the blastocyst stage. An increased blastocyst formation was found in 54.3% of patients whose daily protein intake was greater than 25% vs. 38% blastocyst formation in patients whose daily protein intake was less than 25%.

The pregnancy rate was also significantly improved in patients with greater than 25% daily protein intake (66.6 % vs. 31.9%).
