Meet Kyle

" My confidence has ... shown up! I had none before! 


I will be forever grateful for the day I signed on with Kyle Frank and the Diet Doc! After trying many other "diets" and seeing a little success and then nothing, I was frustrated and ready to give up. Kyle stepped in with a perfectly timed introduction to the Diet Doc and I was ready to give it one more try. I'll never have to go through that feeling of defeat again!" 




Debbie W.

" Allowed me to learn how to eat normal foods


Kyle and The Diet Doc have allowed me to learn how to eat normal foods and still lose weight.  This is completely sustainable “diet” that will change your life! For me learning the right combination and portions made all the difference and not having to feel guilt when wanting to enjoy a food that most plans would make you omit. The support and advice is second to none. Thank you so much!"
