Meet Karlie
Certified Nutritional Practitioner (CNP)
& Metabolic Health Coach
I’m Karlie Holtby, a holistic nutritionist, metabolic health educator and founder of the Metabolic Reprogramming Reset. For more than a decade, I’ve helped women and men understand what may be driving stubborn weight, low energy and hormonal changes.
My approach blends ancestral wisdom, species-appropriate whole foods and modern nutritional science to address root causes instead of simply managing symptoms. I teach in a way that’s practical, personal and refreshingly honest, so you can stop fighting your body and finally learn how to work with it.
27 POUNDS LOST AND I FEEL LIKE MYSELF AGAIN.
“This program has truly changed my life. When I began, I was exhausted, stuck and overwhelmed. I had restless sleep, brain fog, afternoon crashes, irritability and no motivation. I thought I was heading into perimenopause. I simply didn’t feel like myself anymore.
The guidance was clear, direct and foolproof, exactly what I needed. There was zero pressure, just consistency. I committed to myself, learned to listen to my body and slowly began noticing changes. Then other people started noticing too.
Every single one of those symptoms? Gone. I wish I had taken before pictures, but I wasn’t confident enough to believe I would follow through. Three months in, I finally did. Today, I stood in front of my daughter’s camera and she said, ‘Mom, look how strong you are.’ That right there is everything. Twenty-seven pounds lost and I feel like myself again.”

I WAS TERRIFIED THAT FLEXIBILITY WOULD MEAN GAINING THE WEIGHT BACK.
“I recently decided to try the Flexible Stage of MRR, and I was so nervous that I would fall back into my old habits and slowly begin gaining the weight back. I entered this phase 23 pounds down. Today, I’m down 26.6 pounds and I’ve lost another inch from my hips! I’m experiencing flexibility in the modern world, and it’s working. I’m still losing while learning how to make this a sustainable lifestyle. I haven’t seen this number on the scale in probably 15 years. But the greatest victory is this: my body feels safe again.
Thank you, Karlie, for sharing everything you’ve learned with us.”

17 TOTAL INCHES LOST BUT HOW I FEEL IS THE BIGGEST WIN.
“I finally measured myself again for the first time since starting MRR. Honestly, I hadn’t felt the need because I already felt amazing and could see such a difference in my body and so could my husband!
From October 14 to February 20:
Neck: 14” → 13”
Arms: 14” → 12”
Chest: 39” → 36.5”
Waist: 33” → 29”
Hips: 39” → 35”
Thighs: 24” → 22”
Calves: 15” → 14”
Ankles: 9” → 8.5”
That’s 17 total inches lost.
Before MRR, my weight consistently stayed between 160 and 168 pounds. I recorded 162 pounds on my first day. Now, I consistently maintain between 138 and 142 pounds.
I’m loving how I look, but even more importantly, I love how I feel.”

READY TO GO ALL IN?
If you’ve repeatedly lost weight only to gain it back, the problem isn’t your willpower. Most programs focus only on the weight while ignoring the metabolic imbalance driving it. MRR goes beneath the symptom. This 12-week program teaches you why your body stopped responding and how to rebuild the conditions it needs to feel safe, energized and metabolically flexible again. Your body isn’t broken and getting older does not sentence you to a slow metabolism. There’s no calorie counting, macro obsession or forcing your way through another temporary plan. Through species appropriate nutrition and step by step metabolic education, you’ll learn how to work with your biology instead of constantly fighting it. What makes MRR different? You won’t leave with another list of rules. You’ll leave understanding your body, knowing how to navigate real life and equipped to maintain your results without returning to diet culture.
Weight loss becomes the by product, not the lifelong battle.
