There Is So Much Noise Out There. Let Me Cut Through It.
Intermittent fasting. Low carb. High protein. Hormone replacement. No cardio. More cardio. Train less. Train harder.
If you've spent any time searching for answers about your changing body, you've probably been buried in conflicting advice. Most are written by people who have never trained seriously, never studied female physiology at a doctoral level, and never personally experienced what you're going through.
I have done all three.
My name is Dr. Jen Case. I'm 44 years old, a Brazilian Jiu-Jitsu black belt, a 15x IBJJF Masters World Champion, and a former professional MMA fighter. I have a PhD in Human Nutrition and Performance, and I've spent my entire adult life studying and living at the intersection of science, sport, and the female body.
And about two years ago, my own body started changing in ways I didn't expect.
Despite training at an elite level, eating the way I always had, and doing everything "right" — my body composition began to shift. Recovery felt different. Energy wasn't as reliable. I noticed things I couldn't explain away with training load or sleep.
I was entering perimenopause.
Here's what I want you to know: even with a PhD and decades of coaching experience, navigating these changes was confusing and at times deeply frustrating. Not because the science doesn't exist — it does. But because almost no one is translating that science into practical, actionable guidance for women who are still training hard and refusing to slow down.
So I made that my mission.
I want to be transparent about what my qualifications actually mean for you, because alphabet soup after a name doesn't tell you much.
PhD in Human Nutrition & Performance — Kansas State University This means I didn't just read about nutrition science. I conducted original research, analyzed data, and spent years understanding how the body responds to food, training, and hormonal changes at a cellular level. When I give you a nutrition strategy, it's not based on trends. It's based on evidence.
Board-Certified Specialist in Sports Dietetics (CSSD) This is the highest credential in sports nutrition. Less than 2% of registered dietitians hold this certification. It means I specialize specifically in fueling athletic performance — not just general healthy eating.
Registered Dietitian (RD) Unlike the term "nutritionist," which anyone can use, an RD requires an accredited degree, supervised clinical hours, and a national board exam. It's a legally protected credential that holds me to a professional and ethical standard.
Certified Strength & Conditioning Specialist (CSCS) I don't just coach nutrition in isolation. I understand how strength training, programming, physical adaptations, and how to integrate them with your fueling strategy so everything works together.
I believe in three things above everything else:
Start with the science. Every recommendation I make is grounded in current research on female physiology, hormonal health, and athletic performance. Not bro-science. Not Instagram trends.
Make it livable. The best nutrition and training plan is the one you can actually sustain. I build strategies around your real life. Your schedule, your food preferences, your training demands.
Trust your data, not the noise. We track what matters, adjust based on how your body actually responds, and ignore the rest. No extremes. No quick fixes. Just steady, sustainable progress.
You deserve a coach who understands that you are not a 25-year-olds, that your hormones are not an obstacle to work around but a factor to work with, and that your goals of feeling strong, capable, lean, and healthy for the long haul completely achievable with the right strategy.
I built this practice for women exactly like you. And I show up every day as living proof that it works.
