Just in case you’re wondering what Trim Healthy Mama is, here is a quick video of Serene Allison and Pearl Barrett, the authors of Trim Healthy Mama, giving the basics of THM.
There is no way around having to read either the original Trim Healthy Mama book or the newer Trim Healthy Mama Plan book. It is vital that you understand the concepts discussed in the book so you can make THM work for you. However, Gwens-Nest.com has a handy Quick Start Guide that is like Cliff Notes for THM. It can help you get the hang of things as you read (and probably re-read) the book to master the THM lifestyle.
