The big topic of discussion the last few months has been around scientific research. We are seeing a lot of information rolling out, and it seems everyone is citing the term "based on the science". While it is great that people are so interested in research, there are definitely some things you will want to know to discern good research from bad research.

This is why Dr. Rachel Keith is on the show today. She is in the middle of 2 long term research projects, so she explains all the details that go into conducting a study, and all the variables they need to account for.

This episode will help you recognize how difficult research can be, and why it might not be the best idea to cram what should be years worth of research into just a couple of months. 

When you fast track research, you can run into issues where previous research has to be retracted due to insufficient data.

What To Expect From This Episode

  • What does the Scientific Process look like to conduct great research
  • How do you account for all the possible variables that can influence the results
  • How does the environment impact our health and cardiometabolic disease
  • What happens when you try to condense the length of studies from years to months


  • [2:00] Dr. Rachel Keith loves the "puzzle" component of research, but also brings it back to how it impacts people
  • [3:00] The environment accounts for around 80% of someone's risk to cardiometabolic disease
  • [4:30] Dr. Rachel shares how complex research is and how long it takes to discover an outcome
  • [7:30] Right now we are trying to break research down that usually takes years to conduct into a condensed version within months or a year
  • [14:45] As a researcher, you have to think through all the different variables that can impact the results of the study
  • [20:00] You will always have variables in long term studies that you never predicted to happen
  • [23:00] For Dr. Rachel's long term environmental study, they are collecting lots of biological information to try and cover different variables
  • [30:00] The studies done now helps to improve futures studies
  • [34:30] Her second study is testing how different types of forests can influence forest immersion
  • [36:30] Some people don't understand why we keep researching the same things, and it is because we are still learning more about these subjects
