A one-cycle protocol for cycle-aligned eating, training, and energy management — for women still cycling and for women in early perimenopause. Based on the four-phase hormonal rhythm of the menstrual cycle.
A woman's menstrual cycle is a 28-32 day rhythm divided into four distinct hormonal phases. Each phase has different metabolic needs, different optimal foods, different ideal training intensities, and different cognitive strengths.
Most women have been taught to ignore this rhythm — to eat the same diet, do the same workouts, and operate at the same intensity every day. This works against women's physiology and produces the predictable mid-cycle fatigue, pre-menstrual crashes, and chronic underperformance that defines so many women's lived experience.
The Cycle-Sync Reset is the structured protocol for living in alignment with this rhythm over one full cycle. It's delivered inside the Fast Like a Girl 90-minute intensive and is also relevant to women in the Menopause Mastery programme working with a more irregular perimenopausal cycle.
Lowest energy. Warm, mineral-rich foods (bone broth, dark leafy greens, root vegetables). Gentle movement only — walking, restorative yoga. Sleep prioritised. Reflective work, journalling, planning.
Energy rising. Light, fresh foods — sprouts, fermented vegetables, lean protein. Build-phase training: strength, new movements, learning new things. Cognitive peak — best phase for hard creative or strategic work.
Peak energy and confidence. Cooling foods, lots of vegetables. Highest intensity training. Social connection peaks. Best phase for hard conversations, presentations, networking.
Energy gradually drops. Warming, grounding foods (sweet potato, butternut, complex carbs, magnesium-rich foods). Moderate training, less intensity in the final week. Detail-oriented work; not the time for big new starts.
This protocol is appropriate for women who present with one or more of the following:
The protocol draws on published research and clinical practice across functional medicine, women's hormone health, and nutritional science. Selected references:
