Weight and health were never meant to be separate
For most of us, they were. We were taught that weight loss was the approach, and diet and exercise were the tools. But weight loss is an umbrella term for too many things we don’t want to lose: bone, muscle, hair, resources and faith in ourselves.
At eight, I was put on my first diet. I was told to eat less to lose my belly.
But my belly was a health signal. Years of antibiotics had compromised my digestion. Diets didn’t fix it; they left my body depleted and me feeling like a failure.
So I get it. The trying. The dieting. I do this work for all of us who were taught to chase weight loss instead of asking what our bodies need.
That’s why I created the Weight Health approach. It’s not about the number on the scale or another diet. It’s about decoding your body’s signals and using those insights to create a plan that supports your health today and tomorrow.
Here, you’ll learn to understand what your body needs, from food, supplements, medications and lifestyle choices, and, most importantly, how to make it all deliciously doable in your life.
What is weight health?
Weight health means the parts that make up your weight (bone, muscle, fat, water and a little ash) are in the right proportions, so your body has what it needs, when and where it needs it, and can use it to sustain optimal health.
It’s not a number on a scale. It’s how well your body is running, and it’s personal and doable.
Weight Health IS your best shot at optimal health, today and tomorrow.

In their words
Ashley is the most knowledgeable nutritionist that I have ever worked with. She really cares about her clients and is able to work around food intolerances and address different personal nutritional needs. It seems like there is nothing she doesn’t know about nutrition.
In 90 days, I lost 15 of the 20 lbs (2 inches off my waist) I wanted to lose, am off pain and acne medications, and I didn’t need the GLP-1 shot! I love my plan, how I look and I feel like a better mom!
For my entire life I had dealt with unpredictable intense chronic gut pain. I met Ashley 15 years ago and she opened my eyes to a new way of eating and caring for my overall body. Since then the pain has been eliminated and Ashley has remained my north star for guidance. Her insights have been nothing short of a miracle transformation in my life.
Individual results vary.
