About Beyond Diet
Stop Counting Calories, Start Eating Well and Start Living!
Please allow us to introduce you to what we are all about. At Beyond Diet, we not only offer revolutionary nutrition information, but a community for everyone to share, learn, and explore. Our intention is to offer a comprehensive gluten-free program that will help people enjoy a healthy state of being while achieving an ideal weight for that individual. Through BeyondDiet.com, members get access to healthy recipes, individualized daily meal plans and exercises, and support each other throughout their journeys.
Beyond Diet started with two friends, one with an idea and the other with a plan, and has grown into one of the largest health and nutrition programs online today. Isabel De Los Rios, a certified holistic nutritionist and certified exercise specialist, developed a nutrition plan she wholeheartedly believed in after extensive study and her experiences with clients. When it came time to share her knowledge, she turned to her long time friend, Jeff Siegel to help spread her principles beyond her current reach. After years of evolving the program, Isabel and Jeff along with several other friends created Beyond Diet as the culmination of all the experience and feedback received over the tenure of our existence.
Our mission is simple: To help over ONE MILLION families live healthier. We are committed to providing the best resources for our members and educating our community as we continue to constantly improve ourselves and our company. Whether you’re here to try something new or to continue a lifelong mission, we are here to support you and to help you achieve your healthy eating and weight loss goals.
We not only enjoy hearing your feedback, it’s a necessity for us to deliver the best program existing today., For those who have been with us for any amount of time know that we value your input greatly and take action whenever we can to benefit all members. Here at Beyond Diet, we hope you feel connected with each other, the program, and the company. Thank you for taking the time to get to know us.
