Twin Hills Weight Loss, LLC is now officially known as inStriv. While our personalized plans for successful fat loss and one-on-one customized counseling will continue to be the same successful system that has helped thousands of clients lose weight and keep it off, we are sporting a brand-new logo and a new look will soon follow that truly represents our goals, our growth, our mission, and our evolution.


The new inStriv brand marks a significant milestone in the Twin Hills Weight Loss story and provides an opportunity to reflect on everything we have achieved and everything we aspire to become as we move forward into an exciting future. With our new InStriv rebrand, we plan to take our message of a personalized physical, psychological, and physiological approach to fat loss to a wider audience, making fat loss more accessible and achievable.


  • Psychologically. Learn why you crave certain foods and why you eat when you are not even hungry.  
  • Physiologically. We train your body to burn fat instead of store it.  
  • Physically. Look and feel better with our 100% natural program.  

Along your weight loss journey our highly skilled team will meet with you (usually on a monthly basis) to check in, coach, mentor and challenge you. They are there to help keep you on track to your health and weight loss goals. Our 100% natural program includes foods that can be found at your local grocery store. We adjust your plan as needed to make sure you’re right on track to reach your weight loss goal. Our certified weight loss specialists will not have you count calories or put you into a workout routine. At the end of your program you will have learned what you can do to keep the weight off. Our program is not a diet plan – it’s a healthy transformation for sustainable weight loss!
