"First time for this challenge. I have been doing IF for two years with occasional 72 hour fast (maybe 4 per year). Have really enjoyed this challenge and being in this group. Have learned soooo much! Would definitely join this NHD 100 YH challenge again. For some reason doing these longer fasts are harder when you don’t have the group to support me. I guess I need to cling more to my why/mission statement."

Bruce P.

"Wish I could express just how amazing I’m feeling. From mental clarity, to physical energy.. plus mood and feeling calm, I am going to MISS this group so much; checking in every morning, the coaches and lessons and support, and the members whom I’m getting familiar with ❤️I’ve learned my fasting from many sources over the years, and have fasted with other groups but with no real “direction”. This will forever be my fasting “home “… because it’s just… everything! It works, it’s safe…Best investment I may have ever made for myself. My gut symptoms have not improved (yet).. but I still trust this process, and have my coach Ali to help me figure it all out going forward."

Ginger F.

"I have not had better numbers in almost 5 years that I have been tracking. Weight down, blood sugar down, ketones up. I did a lot of tweaking and coaching prior to this to truly understand what works best for me and this challenge allowed me to put it all together to make a huge difference. And I did not fast but instead did midday OMAD and discovered that this is a great formula for me. I am almost never hungry. The absolute key for me is to continue most of this and not go back to what I was doing prior to the 100 Year Heart Challenge. It’s a lifestyle that can be a little more flexible and relaxed some days but for the most part I know that this is how I will live to feel my best and operate this old machinery of mine to its full capacity. Thank you Dr. Wolfson and staff and all of you on this journey who have been sharing."

Lisa L.

"I do have to say, this Heart Challenge is more than I expected. You coaches have done a fabulous job. The Q and A's are jam packed with great info and the presentations are really good. I am grateful that you and the other coaches are really focusing on making things practical and doable, but doing it safely. I am enjoying the interaction with the other challengers too. So thank you."

Shawna B.

"I lowered my blood sugar but the game changers are Mg/Kick Start my heart and use of salt which helped chest pressure/tightness due to leaking heart valves. Losing 4 lbs. is a Bonus.The advice via presentations along with the diet/supplements greatly impacted my health.Thank you to the Coaches esp. Ali and Lara and for answering my questions. Special shout out to Lara for email support too. I am so grateful to be part of this NHD Challenge."

Val C.

"Thank you all again from the depth of my soul. You have truly changed my life for the better! This program was life changing for me. I am hopeful that I can incorporate what we learned into a much healthier lifestyle! Thank you again to all of you coaches. You have a gift in guiding others towards better health. Your support and interaction have made all the difference with this program!"

Staci C.

"I cannot believe how great this second fast has been!! Other than some watery stool today and being a little cold yesterday, I have had no symptoms! I am not hungry, have slept well, have lots of energy, and a great attitude!!! Much easier than the first fast. I attribute the success to this being the second fast and a huge increase in mineral intake. I’ve done Coach Ali’s recipe in 8 ounces of water 3 - 4 times per day. I have a Keto Mojo but have not used it. I hope to do so next time I fast. I will reiterate what others have said … the information provided by our Coaches, Doctors and all of you participants has been amazing!!!! Thank you all!! Can’t wait for the next Challenge!!!"

About Dr. Lauren Lattanza NMD, FACC

Dr. Lattanza Office Visit with Patient

As a Naturopathic Physician, I am trained to treat the whole person and get to the root cause of disease.

I went to Arizona State University where I graduated with a bachelor’s degree in psychology with a depth in physiology and minor in Spanish. After my undergraduate degree I was working on prerequisite classes towards medical school, which is when I came to learn that my values identified best with the principles of naturopathic medicine. I knew that I wanted to help patients identify the causes of disease and be able to offer treatments which would improve their health rather than simply treating symptoms.

I dedicated the next 4 years to the Southwest College of Naturopathic Medicine in Tempe, Arizona where I attained my Doctorate of Naturopathic Medicine. I served as Class President all 4 years, Board of Trustees – Student Trustee, spoke as the Club President for our branch of Toastmasters, and was voted by my peers and attending physicians to earn the Outstanding Leadership Award for the Class of 2020. Throughout medical school I took it upon myself to work alongside MDs, DOs, chiropractors, and functional medicine practitioners in addition to naturopathic physicians.

As a Spanish speaking student, I was able to volunteer with community clinics around Phoenix and provide free healthcare to low-income families. Due to this combined exposure, I came to find my passion in treating cardiometabolic and digestive disorders that are all too common, yet largely preventable. I took the opportunity to learn the broad spectrum of healthcare so I can ensure that I am able to provide my patients with the best options.
