Women's health coaching — food, biology, and the nervous system, integrated.

Strong.
Nourished.
Unapologetically you.

Nourish your Ruby SOL. Reclaim your vitality.

For women who've been dismissed, overlooked, and told their labs were fine.

Marisol Sanmiguel, founder of Ruby Sol Food & Vitality

You run everything else on a system.
Your health runs on willpower.

The rest of her life

  • Career — tracks metrics, adjusts strategy, reviews quarterly
  • Finances — budgeted, invested, reviewed
  • Kids' schedules — optimized, coordinated, non-negotiable
  • Relationships — intentional, maintained, invested

The health layer

  • Energy — depleted, foggy, running on caffeine and willpower
  • Midsection — stubborn weight that won't shift despite trying everything
  • Doctors — told their labs are fine, but they don't feel fine
  • Body — disconnected, dismissed, done being told to just "eat less and move more"

"You've been treating your body like a problem to solve. What if the answer isn't more discipline — what if it's a different relationship?"

— Marisol

Four pillars. One integrated system.

Regulation precedes restriction. The nervous system decides everything — we start there.

PILLAR 01

Restore & Recharge

What would change if your nervous system felt safe right now?

Nervous system regulation as the load-bearing foundation. Sleep optimization, somatic awareness, and the science of rest — not laziness, not "just meditate." You can't digest in survival mode. Everything starts here.

"You can't digest in survival mode. Everything starts here."

PILLAR 02

Fuel with Freedom

What would change if food wasn't a source of daily guilt or confusion?

Anti-inflammatory, non-restrictive nutrition. Consistent meal timing, adequate protein, gut healing — not a food rules system, a framework that works with your biology.

"Freedom in, freedom out."

PILLAR 03

Empowered Strength

What would change if your body felt like an asset instead of a liability?

Progressive strength training built around compound movements, biomechanics, and real-world capability. Training that builds confidence without adding threat response.

"Slow burn, not scorched earth."

PILLAR 04

Rewired Focus

What would change if the gap between knowing and doing finally closed?

The mindset and pattern layer that makes the first three pillars stick. Belief work, identity reframe, and the nervous system re-patterning that happens when the body is no longer in constant threat response.

"The operating system, not the app."

College was a blur of fitting in, late-night dining hall runs, and a relationship going nowhere. I compensated the only way I knew how — turning fitness into an obsession. I taught myself to exercise from YouTube, counted every calorie, demonized carbs, and survived on chemically processed foods. By fall 2014, I'd lost a dangerous amount of weight. My hair was falling out. My kidney function was at risk. My body was screaming at me.

My last semester abroad in Rio de Janeiro changed everything. A host family that embraced me. Rainforests and corner buses. I came home with a completely different relationship to my own body — less gripped, more alive.

I brought that energy to Miami and my career at Equinox, where I trained clients and learned from world-class leaders in the industry. I discovered what I'd destroyed through my own experience: the body doesn't respond to punishment. It responds to safety, biology, and trust. I became an artist in the kitchen — real food, bold flavor, energy instead of depletion.

What I learned through my own healing changed how I coach: inflammation doesn't stay in one place. My bloating, my food sensitivities, my back pain — I thought they were separate problems. They weren't. When I repaired my gut, I fully healed my back. That integrated approach — anti-inflammatory nutrition, nervous system regulation, targeted movement — is what Ruby Sol is built on.

Today, Ruby Sol is the practice I built from both seasons — the wreckage and the science. Anti-inflammatory nutrition. Nervous system regulation. Strength training that builds women up instead of breaking them down. Not another food rules system. A different way of understanding what your body actually needs.

"The body isn't broken. The nervous system running in perpetual threat response is."

Real women. Real outcomes.
No performance.

Marisol makes eating healthy simple and easy! I feel so much more confident and comfortable in the kitchen and am finally figuring out what works for me!

Maggie Palermini

I learned how to manage a gluten free lifestyle to assist with improving digestion and now am mostly gluten free. An unexpected result was that I have fewer headaches.

Leda Silver

No, I'm not a "perfect eater" but Marisol taught me that I don't have to be. I just have to learn healthier ways to improve myself and refer back to what she taught me to course correct.

Fei Daniels

I grew stronger and gained endurance. I strengthened my back and core, gained muscle mass and muscle tone, and lost body fat. I appreciate Marisol's holistic approach to fitness.

William Jelke

This program is for everyone. No matter your age, sex, income etc. We all eat and we all need to learn to eat in a way that does us good.

Nathalia Arbelaez

This is a shame-free, non guilty approach to nutrition. I am eating healthier with cleaner choices, which in turn, makes me feel better and not bloated!

Before you apply

Most nutritionists and dietitians give you a meal plan and send you home. Their advice is often prescribed, cookie-cutter, and outdated. They don't work with gut health, inflammation, or hormones. And they know nothing about behavior change. Ruby Sol is different: anti-inflammatory nutrition, gut-informed approach, nervous system regulation, and behavior change — all integrated. I work with food when that's the entry point, and with the nervous system when that's what's needed. The difference is in the depth, the perspective, and the integration.
Functional medicine doctors are excellent at diagnosis and protocol design. Ruby Sol fills the gap between visits: the daily nervous system work, the habit integration, the accountability that makes a protocol actually stick. We don't replace your doctor — we do what protocols alone can't do.
No. The Slow Burn method is designed for women at every movement level. If you're currently doing nothing, we start where you are. If you're already training, we optimize what's there.
Yes. All tiers except the in-studio Strength & Vitality class are available remotely. Elite Vitality and the Monthly Container are remote-first. Vitality is fully remote.
Book a Vitality Strategy Session. It's free, it takes 30 minutes, and it will tell you whether Ruby Sol is the right next step — whether that's with us or somewhere else. Marisol reviews every session request personally.
It depends on the tier, and which tier fits you isn't something either of us can know before we talk. We go through the options on your Vitality Strategy Session, once I understand what you actually need. These are serious programs for serious clients, and the first part of transformation is commitment. I offer different options to make this doable if you're ready to be coached.
