“Feeling real hope for the first time in ages, I began working with the Fasting Method coach Rachel Primo and lost 50 pounds in 15 months (Aug 2017-Oct 2018). With a height of 5 feet 5 inches, I have dropped my weight from 249 pounds to 199 pounds – and I continue to lose weight. My hemoglobin a-1c dropped from 5.8 to 5.0 and C-reactive protein dropped from 31 to 18. I have completed one 7-day fast, several 5-day fasts, and many 72-hour and 48-hour fasts.”

“At age 61 I feel better than I have felt in decades as I continue the adventure of losing weight and gaining health. My primary motivation is increased longevity – I want to be here to enjoy life with my wonderful family. My heartfelt thanks to everyone at TFM!”

“I found Jason Fung’s system for intermittent and extended fasting. It appeals to me because Fung’s reasoning that diabetes is a nutritional disease makes a lot of sense. I started my first fast in late December 2017, a 48-hour stint without food. It was so hard that I decided to follow it up with a seven-day fast, thinking that once I’d done a marathon-length version, those shorter fasts will seem easy by comparison. It worked. Over my first three months, I lost 25 pounds. The following months saw more weight loss and none of the creep-back of poundage I’d seen with other diets.”

Sandra M

“When I started The Fasting Method, I weighed 231 pounds, I wore a size 16-18; today, less than 6 months later, I weigh 180 pounds and wear a size 12-14; my goal is to get to 150 pounds and wear a size 8-10 by my 39th birthday in April 2019.”

“My favorite protocol is the one that I adapt according to my week. I follow the No. 1 “rule” of TFM, make fasting part of your lifestyle.  Because of this, I feel that I will be able to sustain this healthy lifestyle. I feel happy and proud to belong to this beautiful family!”

“I joined the The Fasting Method program in June of 2017 with an A1C of 9.2 and fasting blood sugars of 200! I was afraid to do 24 hrs and longer fasts and hence decided I needed a coach! Nadia Pateguana was my coach, and I started doing 42 hr fasts 2 to 3 times a week. It was magical! From June of 2017 to February of 2018 I dropped to a size 2! I made many keto meals but treated myself to higher carb meals quite a few times a month. I learnt to feast and fast intelligently. My A1C came down to 6.5 (from 9.2) within 4 months. I don’t get fasting blood sugars of 200 anymore. Today is March 25th of 2019 and I have come a long way! My blood sugars are always within the normal to prediabetic range.”

“I am forever grateful to Dr. Jason Fung, Nadia Pateguana, Megan Ramos and everyone and anyone associated with the TFM program.”

“I wanted to thank the Fasting Method in general, and Rachel Primo, in particular, for helping me to improve my overall health. I started shortly after in November, shortly Thanksgiving, in 2018. I immediately began to see results, and by February of 2019, I was in a solid place. In the few weeks that we’ve been working together, I’ve dropped 17 pounds of fat, reduced my waist circumference by 11 centimeters and dramatically improved my liver enzyme test results. I struggled my whole life to reach my goals, and I’m so far beyond anything I ever thought might be possible. THANK YOU!”

“In May of 2017 I participated in my first extended fast, thanks to the support of Brenda Zorn and the ketogenic forums. This lowered my fasting blood sugar by almost 50 points immediately and permanently. It also spurred on even more rapid weight loss. By mid-June I was down to 325 pounds, an over 50-pound loss, and my A1C was 5.5%, the best I’d ever had measured.”

“I have battled obesity for my entire adult life and as I got older the effects of the weight gain took its toll. One year ago, I had a hip replacement which was very difficult to recover from because of my obesity. I literally could not walk due to back pain and a weak hip.   

Today my life is very different. I am losing weight and becoming healthy with the wonderful tools provided by the Fasting Method Community. The education provided by the program and especially my Coach Larry Diamond has helped me to learn about Intermittent and Extended Fasting and how to live a healthy life style utilizing a Ketogenic Diet.”

John P

“ I started with the Fasting Method on May 1, 2017.  After just six months on the TFM Program, I had lost 75 pounds and my fasting insulin had dropped to 4.3 micro IU/M and my fasting blood glucose was 75 mg/dl!  Not just “normal” but really great! I was amazed. March 1, 2018 I had gotten rid of 100 pounds and have kept them off plus or minus 10 pounds ever since.”

“I don’t think I could have done it without that coaching initially.  I always learned so much from both Nadia and the other TFM members on the call.  If you’re feeling like you want to bury your head in the sand because you’ve “messed up”, DON’T!  Post something on the forum or Facebook site.  You will be amazed how quickly, and how much, non-judgmental support you will be offered by others who have been there or who are there right now.”

Dolly K

“It is now seven months since my first fast and the discovery of The Fasting Method and Dr. Fung in April 2018. I am the lightest and fittest I have ever been in my life. I haven’t had signs of low blood sugar since late April, I train about 10 hours a week and only use electrolytes and water. I fast daily (usually a 16/8 or 18/6), follow a keto & paleo lifestyle and continue to drop fat and gain muscle. I literally owe my life (and thousands of dollars) to Dr. Fung and the TFM program. I can now look to the future and focus on continuing to improve my health, becoming a better athlete, and having a healthy relationship with food.”
