Why re:vitalize Will Work For You​

Our Team Approach

There are many nutritionists out there, but few offer the support and guidance that we do in our program. We are passionate about your success and take every step we can to support you with a personalized approach to long-term, sustainable weight loss.

Personalized Nutrition Plans

Our program starts with a BioScan™ that provides detailed insight into your biometric data and unique nutritional needs. We use your BioScan™ data and the information we gather from our discussion about your goals and health history to create a personalized nutrition plan.

Our plans are centered around sustainability—they incorporate dozens of recipes that are full of delicious, whole foods tailored to your dietary preferences, so you’ll stay loving the foods you eat. This model provides an easy-to-follow meal plan without harsh restrictions, so you never feel tired, hungry, or lethargic and can maintain progress past the program.

Ongoing Support and Monitoring

Throughout the process, we offer consistent support and monitoring through daily text message check-ins and weekly, biweekly, or monthly in-person or virtual check-ins, depending on the program you’re enrolled in. 

During these check-ins, we’ll discuss how you are feeling about the program, monitor your progress toward your goals, and assess your current biometrics. Along the way, we’ll make personalized adjustments as needed so you stay on track to success and stay feeling amazing throughout your journey.
