@colleenyoung Thanks for your nice note and the link to the Mayo article. Along with intermediate fasting and Keto, I'm exploring tea and all it's amazing medicinal properties. When I was growing up, all I knew was Lipton tea in bags, which is pretty sad. Now I'm trying a myriad of varieties and mixes, which are delicious, give me energy, and are helping me lose weight. I'm actually starting a coached 14 day intermittent fast using different teas beginning February 22. Participants don't have to follow a strict Keto plan but can. The program features Dr. Jason Fung, leading expert on fasting, obesity, and Keto; Dr. Will Cole, leading expert on functional medicine and Keto; and Margaret Ramos. There are two ways to sign up: 1. If you buy tea from Pique Tea, you can participate for free -- https://help.piquetea.com/hc/en-us/articles/1260802080690-What-is-included-in-the-Fasting-Practice-; and 2. If you sign up for a month's program through the Intermediate Fasting website. https://thefastingmethod.com/ you can participate with no additional charge. You have to register by February 19. Several days have a 16/8 fasting window and others a 20/4. Since I've been doing the 16/8 without using Keto, I want to try the 20/4 using Keto and will probably do that for the 14 days. How to do all of this is on the internet, on YouTube, or in books; but it's hard to change eating patterns and habits of 74 years. I think it will be fun and helpful doing it as part of a group for 14 days and have a chance to hear and interact with world famous experts...for the price of some tea. Thanks for everything you do help us along our way to better health. Nancy
