Choose an evidence-based approach to the ketogenic diet.

The ketogenic diet is the hottest diet of the past several years. And predictably, it’s attracted a host of charlatans and hucksters trying to sell it as a magic solution to all of your ills.

For Evidence-based Keto, we reviewed decades of research to help you understand all the pros and cons of keto, so you can decide if it is the right diet for you.

  • Get answers you can trust to the most debated questions — we’ve gathered and analyzed the latest evidence on keto’s effect on weight, exercise, muscle, diseases, and more.

Learn everything there is to know about the most popular protein supplement.

To build or preserve muscle, no supplement is more popular than whey protein, and it’s also one of the very few products convincingly shown to promote fat loss.

Unsurprisingly, over the years, we’ve received hundreds of questions about whey. We’ve already answered several in our multiple articles on protein in general and whey protein in particular. Now, we’ve answered them all in The Definitive Guide to Whey Protein.

  • Optimize your intake — dose and time your protein to fit your health goals.
  • Stay safe — learn about sourcing and processing, the pros and cons of common added ingredients, and the legal tricks supplement companies use to fool you.
  • Rely on expert, unbiased information — we don’t sell or advertise supplements; we are a team of scientists and our sole focus is on the research.

Why Examine.com?

Examine.com started because we were frustrated.

We were frustrated with supplement companies misrepresenting scientific research. We were frustrated with social media “influencers” peddling products they didn’t use themselves. We were frustrated with famous doctors and mainstream media disregarding context to produce sensationalist headlines.

This frustration drove us to create, in 2011, what we seeked and couldn’t find: a 100% independent company that doesn’t sell supplements or even ad space on its website — a company that lives or dies solely by the accuracy and usefulness of its analyses.

Today, the hundreds of free articles on our website are read by millions of visitors each month, and 50,000 people have bought our publications. Medical doctors, dietitians, coaches, and personal trainers entrust their reputation — and the health of their patients, athletes, and clients — to our analyses.

Like the health professionals, each time you purchase any of our publications, you purchase thousands of work hours from a dedicated team of experts with degrees in nutrition, exercise science, public health, pharmacology, toxicology, microbiology, biophysics, biomedical science, neuroscience, chemistry, and more.
