Welcome
I'm Marnie Astacio
Do you dream of waking up energized, craving-free, and ready to enjoy your day…
But instead, you find yourself stuck in a cycle that feels impossible to break:
-
You wake up already tired—and your energy only dips from there.
-
A bloated belly and stubborn weight gain feel like your new normal.
-
Constant cravings, especially in the afternoon or at night
-
Anxiety lingers beneath the surface, even when everything seems fine.
-
Trouble falling asleep or staying asleep has become a nightly struggle.
-
Joint pain makes even simple tasks feel heavy and hard.
-
Your reflection reveals the stress: dry skin, brittle nails, and thinning hair.
-
Hormone imbalances, blood sugar swings, or autoimmune flares just keep piling on.
-
Feeling overwhelmed or frustrated what diet or supplement to try next
-
You’ve tried to push through, but your body keeps sending signals that something’s off.

Meet your coach...
Marnie Astacio is a globally recognized sugar addiction expert and master nutrition and wellness coach who has helped thousands of women over 40 reclaim their health, lose weight without restriction, and break free from sugar for good. As the creator of the FLOAT Method and a published author, Marnie is known for her compassionate, habit-based approach that meets women where they are—physically, emotionally, and hormonally. Her work has been featured by wellness communities around the world, and her personal health journey fuels her mission to help women feel strong, confident, and finally in control of their bodies again.
Let me tell you a story
When I became pregnant, I was diagnosed with gestational diabetes. I followed the advice of a licensed dietitian and stuck closely to a traditional food pyramid-based plan. Despite doing everything “by the book,” I gained 68 pounds on my 5’2″ frame—and I felt absolutely miserable.
After delivering my beautiful baby, I left the hospital with a 6-pound newborn and 65 extra pounds still weighing me down. I couldn’t understand how that was even possible—but it was. The weight didn’t come off easily. I struggled with constant exhaustion, mood swings, and the emotional toll of feeling like I had lost control of my body.
As I got older, the health issues started stacking up: chronic sinus infections, ongoing back pain, a swollen hand injury that wouldn’t heal. I was repeatedly prescribed antibiotics and anti-inflammatory medications, but nothing truly helped. I began to notice a pattern—the medications were only covering up symptoms, not solving the problem.
That’s when it clicked: I wasn’t just tired or inflamed—I was out of balance. My hormones were disrupted, my blood sugar was unstable, and my energy was at an all-time low. Cravings, poor sleep, and stubborn weight gain had become my norm. I knew something had to change—and fast.
So my healing journey began
I dove deep into understanding the root causes of what was happening in my body. I didn’t just want short-term fixes—I wanted real, lasting weight loss and healing.
I became a Certified Functional Nutrition and Wellness Coach. I expanded my expertise by studying traditional herbalism, Ayurveda, ancient nutrition, biohacking, and energy healing. I also became a Certified Gluten-Free Health Practitioner and a Sugar Addiction Detox Specialist.
Through this education and personal experimentation, I uncovered what truly works. I learned to balance my blood sugar and hormones and replace inflammatory, harmful foods with nourishing ones. I developed daily lifestyle practices that helped restore balance and calm to my body. And the results were undeniable.
The weight came off. The inflammation vanished. My sleep and energy returned. I experienced real food and body freedom—and I felt like myself again.
Today, I teach other women how to do the same.
My story is more than personal—it’s professional. I combine lived experience with deep training and proven strategies to help women take back control of their health, balance their hormones, break free from sugar, and feel confident in their bodies again.
