Trying to conceive? Try the better baby diet of beef, butter & bacon. The evidence

This guide is based on scientific evidence, following our policy for evidence-based guides.

It’s written by Anne Mullens, with the latest major update on June 1, 2020. The guide was medically reviewed by Dr. Bret Scher, MD, on June 1, 2020.

The guide contains scientific references. You can find these in the notes throughout the text, and click the links to read the peer-reviewed scientific papers. When appropriate we include a grading of the strength of the evidence, with a link to our policy on this. Our evidence-based guides are updated at least once per year to reflect and reference the latest science on the topic.

All our evidence-based health guides are written or reviewed by medical doctors who are experts on the topic. To stay unbiased we show no ads, sell no products and take no money from industry.1 We’re fully funded by the people, via an optional membership.2

Disclaimer: Low-carb nutrition and fertility is a unique field without much research or experience. We acknowledge that much of the evidence in this guide is low quality or even anecdotal experience. In fields where there is sparse scientific research, we need to rely on clinical experience from experts in the field. We hope to be able to update this guide in the future as more research becomes available.
