The Metabolic Truce® Method
Coaching designed for the body you're in now.
The Metabolic Truce® Method BODY. MIND. SELF. Your body has changed. Of course it has. So why are we still trying to feed it, train it, and fix it like nothing has changed? This is about understanding the body you have now and learning how to work with it instead of constantly trying to outsmart it. That means looking at how you eat, how you move, how you sleep, how you recover, and yes, what goes on in your head when things aren't going perfectly. You don't need another generic plan, more rules, or another Monday morning restart. You need an approach that makes sense for your body, your life, and what you actually want for yourself. Stop fighting your body. It's time to call a truce.

The Metabolic Truce® Meal Planning
The Metabolic Truce® Meal Planning is the structured nutritional foundation of the Metabolic Truce® Method. Over four weeks, it restores protein rhythm, stabilizes hunger, and supports sustainable fat loss through tier-based calorie placement and consistent nutritional structure. It is designed specifically for midlife women who want clarity — not chaos. This is a metabolic foundation, not individualized one-on-one coaching with high-touch accountability or weekly macro recalculations. If you are seeking a personalized strategy, you'll need The Metabolic Truce® Strategy Membership.
Tier-based calorie placement ranging from 1400–2000 calories, with protein-forward macro structure designed to support muscle retention, stabilize hunger, and drive sustainable fat loss, assigned based on activity level, body composition, and dieting history.
A structured 7-day meal template designed to be repeated over 4 weeks to build metabolic rhythm and consistency.
4 weeks of access to the private Metabolic Truce™ Vault, covering cortisol regulation, protein rhythm, hunger signaling, and midlife metabolism.
4 weeks of access to the private Metabolic Truce™ Recipe Library.
App access for the full 4-week foundation.
After enrollment, you will complete a private placement form so that your calorie tier can be assigned intentionally. Please allow 24–48 hours for placement and plan activation inside the app.
Access to the Vault and Recipe Library concludes at the end of your 4-week foundation.
If you would like continued access to ongoing Vault drops, recipe additions, and future program expansions, you will have the option to continue inside the Metabolic Truce™ Membership ($29/month) following your 4-week plan.

The Metabolic Truce® Strength Training Protocol
The Metabolic Truce® Strength Protocol is an 8-week strategic strength training plan for women tired of piecing workouts together from random reels, hopping from program to program, and wondering why their body composition isn't changing despite “working out.” This is not bootcamp chaos, influencer fluff, or a sweat-until-you-collapse approach to fitness. This is structured, progressive resistance training designed to help you build muscle, improve body composition, increase strength, and train with purpose instead of randomness. Whether your goal is to improve muscle tone, build strength, increase confidence in the gym, or create a more intentional training structure in midlife, this program removes the guesswork and gives your body a repeatable signal it can adapt to. This program focuses specifically on strength training progression and execution and does not include individualized nutrition coaching, macro coaching, or meal planning.
Customized 8-week progressive strength training program.
Structured training split designed around your goals, experience level, and training environment (home or gym).
Gym-based OR home-based programming, depending on your available equipment.
Access to the Fitbudd Exercise demo library inside the app.
Strategic cardio recommendations and movement targets.
4 live 30-minute Training Calibration Calls focused on progression, recovery, performance, and exercise execution.
4 weekly Training Calibration Questionnaires for ongoing progression monitoring and program adjustments.
Training adjustments and exercise modifications as needed throughout the program.
Limited in-app messaging support Monday–Friday for training-related questions only, with a 24-hour response window.
Access to the Metabolic Truce™ Vault educational resources during the program.

Metabolic Nutrition & Fitness Coach
When it comes to health and fitness, I lead by example. I also believe that what you can sustain matters a whole lot more than what you can white-knuckle your way through for 30 days. After years of coaching women through changing bodies, changing hormones, busy lives, and everything else that gets thrown at us, I’ve learned something. There will always be another 12-week program, another challenge, another diet, and another promise to completely transform your body. But what happens when it ends? Building a healthy relationship with food and fitness is a lifestyle choice, not a one-night stand. That belief is at the heart of The Metabolic Truce® Method, my approach to helping women stop fighting their bodies and learn how to work with them instead. Body. Mind. Self. Body is about giving your body what it actually needs. Good nutrition. Strength. Movement. Recovery. Not punishing it because it doesn’t look or respond exactly the way it did 20 years ago. Mind is about breaking the cycle of all-or-nothing thinking. No more being “good” all week, blowing it on the weekend, and promising yourself you’ll start over Monday. Self is the part we tend to forget. You’re allowed to want to change your body. You’re allowed to want to lose fat, get stronger, feel better in your clothes, and look in the mirror and think, damn, I look good. You just don’t have to hate yourself into getting there. When I work with women, we build from the ground up with nutrition, strength, and habits that make sense for real life and support long-term metabolic health. No extremes. No starting over every Monday. No declaring war on your body. That’s the truce.

Frequently Asked Questions
Who is this coaching best suited for?
This coaching is best suited for women who feel like they’ve been doing “all the right things” but aren’t seeing the results they expect. Many of my clients are already exercising regularly and eating relatively well, yet still struggle with stubborn fat loss, plateaus, or a body that no longer responds the way it used to. If you’re looking for a more strategic, personalized approach that works with your physiology instead of against it, you’re in the right place.
Who is this program NOT for?
This program may not be right for you if you're looking for: — Quick fixes, extreme dieting, or a one-size-fits-all approach. — If you’re not open to structure, consistency, and making thoughtful adjustments over time, this likely won’t be the right fit. — The work we do here is intentional, data-driven, and designed for long-term results—not shortcuts.
Is this program right for me if I'm already active?
Yes—and in many cases, those are the clients who benefit the most. If you’re already working out consistently but not seeing changes in body composition, it’s often a sign that your nutrition, recovery, or overall strategy needs refinement. This is where a more precise, individualized approach makes all the difference.
What are the different ways to work with you?
All programs are offered under the CRUSH !T Coaching framework—a structured, physiology-based approach to training and nutrition—with current offerings designed to meet you at different levels of support: — The Metabolic Truce™ Intensive (Primary Offering): A fully personalized high-touch coaching experience with ongoing adjustments, weekly check-ins, and direct support. — The Metabolic Truce™ Meal Planning: A structured nutrition plan designed for those who want guidance without full coaching. — The Metabolic Truce™ Subscription (Post-Program): Ongoing support available after completing initial programming, for continued structure and accountability. Most clients begin with the Intensive for the most comprehensive and effective results.
What’s included in the Meal Planning option?
The Meal Planning option provides a structured nutrition framework designed to support your goals. It includes: — A customized calorie-tiered, macro-based meal structure. — Food guidance and organization. — Clear direction for daily nutrition. This option is more self-directed and does not include ongoing coaching, weekly check-ins, or real-time adjustments.
