Fuel Your Flow: The Nutrition Guide for Eating With Your Cycle

Why Cycle-Syncing Matters

If you’ve ever wondered why some weeks you crush workouts and others you can barely get off the couch, your cycle might be the missing piece. Your hormones shift every month, and those changes affect your energy, mood, metabolism, and even how you digest food.

Most diets ignore this. But when you learn how to fuel your body based on where you are in your cycle, everything starts to click. That’s what Fuel Your Flow is all about.

What Is Fuel Your Flow?

Fuel Your Flow is a cycle-syncing nutrition guide created by me, Claire Rifkin, MS, RDN. It’s designed to help women eat in alignment with their hormonal shifts, so you can feel more energized, focused, and balanced all month long.

Inside you’ll get:

  • Evidence-based nutrition recommendations for every menstrual phase (menstrual, follicular, ovulatory, luteal)
  • Meal ideas that support hormone balance without restriction
  • Tips for managing cravings, energy dips, and mood changes
  • An easy framework you can actually stick to

This isn’t about cutting out food groups or obsessing over macros. It’s about learning how to eat in a way that supports your unique biology.

How Eating With Your Cycle Helps

When you fuel your body with the right nutrients at the right time, you can:

  • Improve energy levels and reduce PMS fatigue
  • Support digestion and decrease bloating
  • Balance blood sugar to help with cravings and mood swings
  • Optimize performance in workouts and recovery
  • Feel more in tune with your body, instead of fighting against it

Who Fuel Your Flow Is For

This guide is for you if:

  • You want to feel less burnt out and more steady throughout the month
  • You deal with PMS, irregular cycles, or hormone imbalances
  • You’re curious about cycle-syncing but don’t want a complicated system
  • You want practical nutrition strategies, not another diet

Why I Created This Guide

As a women’s health dietitian, I see how many of my clients feel like their bodies are unpredictable. They’re told to just “eat healthy,” but that advice doesn’t take into account the very real changes women experience every month.

I created Fuel Your Flow to change that. It’s a science-backed, approachable way to eat that honors your body and makes nutrition feel supportive—not stressful.
