Are You Exhausted, Struggling with Weight, and Out of Shape? Admittedly, You're Not Surprised Because You've Been...

Is the reason you haven’t accomplished your goals because


Your health has spun so out of control and now you're overwhelmed, confused, and feeling stuck

But you can’t keep living this way, dealing with these symptoms, pushing through, and just hoping they magically get better. The ‘take this for that’ approach isn’t working. Your time is precious and you want to make the most of it. You’re DONE with the EXCUSES. You’re ready to take ACTION and stop making suboptimal diet and lifestyle decisionsYour body is taking a hit. But you’re NOT sure about where to begin [again] and what’s really going to help.


Hi, I’m Maria Horstmann and I’m a Certified Functional Diagnostic Nutrition Practitioner (FDN-P) – aka “Health Detective”, a Board Certified Functional Wellness Professional (BCFWP), an Insulin Resistance Coach, and a Personal Trainer.


I empower driven, health-oriented professionals, to get to the bottom of their health, weight, and metabolic issues, using the Horstmann Method breakthrough system approach of optimizing their blood sugar, inflammation, and cortisol/HPA Axis. This way, you can restore vitality while supporting the body’s innate healing abilities.

I’ve been where you are. I’ve worked in corporate and pushed myself consistently. I had no ‘true’ energy and without noticing, I abandoned my health. Instead, I used caffeine and sugar to keep me going.

I’m a former sugar addictprediabetic, and insulin-resistant who suffered from various digestive issues, emotional eating, and an eating disorder.

But I transformed my health and lifestyle…

…once I realized it was about making progress, not being perfect. Seeing the DATA (my body’s ins and outs) and knowing the WHY helped me believe, trust, leap forward, and stay on course.

Are You Struggling To Lose Stubborn Weight and Belly Fat?

You know there is more to the ‘Calories in, Calories out’ and ‘Eat Less, Exercise More’ models

Maybe you’ve tried all sorts of diets, and exercise programs, taken supplements, been to doctors, and haven’t received any ‘right’ answers. You’ve even tried weight loss pills or products to improve your metabolism. All the strategies that used to work are just not working anymore. You want to stop the Trial-and-Error Cycle and join a path that will get you long-term results.

It’s because you have gained appreciation for all that your body does for you daily that you’re willing to do what it takes to prolong your vitality and thrive [again].

It's Time to Try the "Horstmann Weight Loss PILL"

What our Clients are Saying...

Kathy Thacker Weight Loss

Take Control Of Cravings, Sugar, Carb Addiction

“At 55 y/o my joints were aching, my diet wasn’t working anymore. First, Maria taught me that weight loss is physical and mental. She pushed me to do things I’d have never done on my own. She saw potential in me and wanted me to see it too. I lost 28.4 lbs in her 90-day Blood Sugar Program. Maria also taught me to love myself more and put myself first. It’s not always easy, but I’ve realized that I’m worth it. She’s truly my life-saving coach.”–Kathy Thacker

Post surgery home stretches_health-coach-personal-trainer_Maria-Horstmann

An Integrative Healing Approach Post Quadruple Bypass

“We met 2 weeks before my quadruple bypass. We talked about nutrition before/post the surgery. God got me home and Maria came over 2 days after. We started with stretches and progressed from there. In 6.5 months, Maria got me ready to climb a 12,000-foot mountain! Maria, as a health coach, I think it’s hard to find someone that is caring, wants that success for you and is able to give you all the tools to succeed.” — Brian Mendel

Maria, Health Fitness Coach, will change your life. Lose weight, build habits for life.

Change Your Life By Discovering Yourself

“Maria will help you change your life! She helped me change mine and was an incredible motivator, listener, and coach. I discovered and reversed why I comforted myself with food and unhealthy behaviors. I lost 30 lbs and have kept it off with the new habits, but more important than the weight loss, I have gained an entirely new appreciation for myself and a confidence that has improved many aspects of my life.” — Mary Severs

Oi, I am Maria Horstmann!

I am a certified FDN-P, aka health detective, a Board Certified Functional Wellness Professional (BCFWP), a personal trainer, and the host of the “Be Fab – Be You Made Simple” podcast. I love prioritizing my health so I can feel energized, healthy, and confident in life. I feel FREE!

But that wasn’t always the case. I struggled with yo-yo dieting, sugar addiction, prediabetes, G.I. issues, and eating disorders until my late 30s. I didn’t know or understood how my choices were affecting me.

Until one day, I sat down and had a come-to-Jesus-moment. It was time to become a better version of myself. I realized that the traditional medical system uses symptoms to run specific tests and use out-of-range results to diagnose and prescribe medications. I wanted to break the cycle that ran in my family. I adopted the ‘opt-in self-care model’. It worked! 

If you’re ready to take back control of your health, get to the root cause of your unsuccessful steps, manage life stressors, and create space for growth so you live independently and age gracefully, I want to meet with you. Let’s make a personalized plan for you to achieve your wellness goals, optimize your health, and feel great again. 

Making a difference in someone’s life and helping them transform challenges into opportunities for growth is what gets me up in the morning.

P.S. I’m Brazilian-born and although I’ve lived in the USA since 1996, my English is not perfect. If you have a grammar phobia, ouch! When you catch my grammatical errors, tell me directly.  Obrigada!
