We make longterm habits easy to stick to!


Most diets are impossible to continue long term. Society has made us feel like it’s never the diet that has failed you, but that you failed the diet. This isn’t true!

At Prevail, we make building healthy habits easy and fun! That’s what Prevailing is all about!


30+ Years of combined weight management expertise.

Clinical Experience

What makes us different?

You won't find any fancy celebrity chefs, long-drawn out explanations, unrealistic tips, or un-relateable foods. We love our beef, potatoes, ice cream, and pizza. 

We know how to help Midwesterner's change their habits because we are born and raised Kansans.


This is why we created Prevail, for you!

Each week, we give you exactly what to work on to build lasting healthy habits.

About Us

Prevail was created by Karli Alderson MD (right) and Stephanie Sisk APRN (left). They met while working as obesity medicine specialists in their hometown of Topeka, Kansas where they saw the impact of weight-related health issues on people and health services first-hand.

They realized a gap in care for a program developed just for those living in the Midwest. They recognize the value in building healthy habits for a sustainable weight versus “quick-fix” diets that many of their patients were duped into. They knew there had to be a better way!
