A community where science, compassion, and real support come together for women ready to heal.
The VIP Collective was created because women deserve answers that finally make sense—and a system that works with the body they have today, not the one they had in their 20s. Our restorative, nutrition-first approach helps women reset, rebuild, restore, and renew their metabolism through every stage of life.
our story
For years VIP’s founder, Kim Nanninga, watched women try harder, eat less, push more, and still feel stuck. These women were doing everything “right,” yet their metabolism, hormones, and energy told a very different story.
As a registered dietitian specializing in women’s metabolic and hormonal health, Kim knew something had to change. Women deserve a plan that honors their biology, supports their nervous system, and restores their metabolism—not one that shames them into restriction.
The VIP Collective was built to be that space.Our approach blends real-food nutrition with the latest tools in metabolic healing, guiding women step-by-step through liver detoxification, gut repair, hormone balance, and sustainable fat loss.
Through our signature methods—the 3-3-3 Meal Planning Method, VIP Hormone Reset, VIP Fat-Burning Nutrition System, and the VIP Microdose Strategy—we help women finally understand their bodies and experience weight loss that lasts.
This is more than a program
it’s a Collective
A place where women feel supported, seen, and guided back to the healthiest, strongest version of themselves.

Meet Kim
Kim Nanninga, rdn
ceo & founderAs a registered dietitian with over 15 years of experience, I’ve always believed that sustainable weight loss starts with healing—not restriction. My passion lies in helping women understand their bodies, balance their hormones, and finally experience the energy and confidence they’ve been missing.
I’ve guided thousands of women through metabolic restoration, real-food nutrition, and hormone balance using our proven VIP Weight Loss System.
My “why” is simple: women deserve to feel powerful, supported, and at home in their bodies again. That belief drives everything I create inside the VIP Collective.
When I’m not coaching, you’ll find me with my family, blending the chaos and purpose of motherhood with a mission to help women rediscover their glow.
