Lose weight with PMOS without another diet.

PMOS Reset is a 12-week small-group nutrition program for women with PMOS (formerly PCOS), led by a Registered Dietitian who lives with it too.

Hi, I’m Jen.I have PMOS too, so I know how frustrating trying to lose weight can be.

Sound familiar?

“I feel like I’m doing everything right, but I’m not seeing progress.”

  • You’ve counted calories, cut carbs, tried fasting, maybe dropped gluten or dairy.
  • Everyone tells you to cut out something different, and you still don’t know what to eat with PMOS.
  • You follow a plan for a few weeks, then life gets busy and you’re starting over on Monday.
  • You want to lose weight, and you also want to stop obsessing over every bite.

None of that means you’ve failed. More often, it means you were handed rules instead of a plan built for your body and your life.

Meet your dietitian

Just a girl with hormone issues

I’m Jen, a Registered Dietitian in New York and a woman in my 30s living with PMOS (formerly PCOS). I spent years hearing “just go on birth control” and “you just need to lose weight” without anyone explaining how.

So I learned how, and now I teach it. My approach is evidence-based and realistic. No perfection required.

Women with PMOS who stopped starting over

~80 lbslost with PCOS, working with Jen
6.0 → 5.6%A1C with PCOS and insulin resistance
Jen is such a helpful dietitian! I’ve lost almost 80lbs since starting sessions with her a couple years ago. She is so understanding and accommodating of my choice to be vegan, too. Can’t recommend her enough.
Jean M. · PCOS client
I was struggling with PCOS and hormonal weight gain; Jen has been a lifesaver. She helped me figure out what foods were best for PCOS, and we found great supplements that helped with my insulin resistance. I could not do this without her!
Abby Gayle · PCOS client
Jennifer is amazing! She’s been very supportive and has really helped me with eating healthier and giving ideas of work around when life gets a little chaotic and cooking or meal prep just isn’t in the cards. There are times I just do not reach my goals and there’s never any judgement but we adjust to make them more attainable. I 10/10 recommend!
Hanna D.
Jennifer is the best! She has helped me lose weight and maintain my health through mid-life hormone fluctuations. She’s caring and supportive and goes the extra mile to help me on my health journey. I would highly recommend her!
Sarah W.
Jennifer is amazing! I have worked with her to improve my health and have lost 40 pounds, and am keeping it off.
