FROM OUR FOUNDER – REED DAVIS

FROM OUR FOUNDER – REED DAVIS

Over 20 years ago, I recognized clients were caught in a “cycle of trial and error” and I committed to being the last person they needed to see.  While working with top leaders in alternative medicine, I ran thousands of labs on thousands of people and learned to identify “healing opportunities.”  Using all-natural, drug-free protocols I made my own observations about who got better and who didn’t, codifying which “general principles of health building” would outperform “specific treatments” being provided by standard and even alternative medicine.

And through this work I then developed the Functional Diagnostic Nutrition®️ Certification Course and D.R.E.S.S. for Health Success®️ Protocol to educate and empower as many people as possible to get well and stay well naturally, so they, in turn, may empower others to do the same.

Episode 210: Periods Should Be PAINLESS w/ Leah Brueggemann, FDN-P

Introduction [00:00:00] Detective Ev: Hello my friends, and welcome back to another episode of the Health Detective Podcast by Functional Diagnostic Nutrition. My name is Evan Transue, AKA Detective Ev. I will be your host for today’s show on painless periods. This is an interesting episode with fellow FDN practitioner, Leah Brueggemann. Leah specializes in hormonal balance for women. She helps women balance their hormones naturally with nutrition, lifestyle, and finally getting to the root cause of what might be going on. At the time of recording this, she has already helped over 300 women get painless periods, stabilize their moods, lose weight, and even scale to six figures in their business. What’s really interesting is when we say scale to six figures, she’s not a business coach, not at the time of recording this, at least.

Episode 209: Intermittent Fasting Is NOT For Everyone w/ Brian Gryn

Introduction [00:00:00] Detective Ev: Hey guys, Evan Transue here, AKA Detective Ev. Welcome to the Health Detective Podcast. I’m looking forward to bringing you guys this episode today about intermittent fasting. We are speaking with Brian Gryn. He is actually one month into the FDN course, although he is not new to the health space by any means. He’s actually been involved in it for almost 15 years, I believe it’s actually more than 15 years. He’s an intermittent fasting expert and he’s one of those rare people on our show that actually did not deal with some severe chronic health issues prior to getting into health. He was one of the ones that was smart enough, unlike myself for example, to actually be proactive with their health and get on top of it before it really hit the fan. There’s plenty to learn here today. A lot of our

Episode 208: Western Medicine vs. Natural Medicine vs. FDN – What’s The Difference?

Introduction [00:00:00] Detective Ev: What is going on, my friends? Welcome back to another episode of the Health Detective Podcast by Functional Diagnostic Nutrition. My name is Evan Transue aka Detective Ev. I will be your host for today’s show about FDN – what’s the difference. What we’re going to be doing today is breaking down the differences in philosophies so people can understand what we are doing at FDN and what other places do. In my opinion, and I think many FDNs would agree with this, there is a time and a place for every philosophy here. In fact, there are many times when maybe we should be using all three philosophies all at once. It can be the most effective form of treatment for the individual. But what really needs to be understood, especially if you’re listening to a podcast like this and you’re trying to understand why
