Luteal phase: what happens, how you may feel, and what helps
Quick answer
The luteal phase is the second half of the menstrual cycle, from ovulation until your next period. It usually lasts about 10 to 16 days. Progesterone rises, body temperature goes up slightly, and many women notice more hunger, lower energy or mood changes in the days before their period.
Key takeaways
- It starts after ovulation and ends when your period begins.
- Progesterone is the main hormone of this phase.
- Resting metabolism may rise a little, which can explain extra hunger.
- Training studies show small, individual differences, so how you feel matters most.
The luteal phase at a glance
| Area | What may change | What can help |
|---|---|---|
| Hunger | Higher, more cravings | Fuller meals with protein, fiber and slow carbs |
| Energy | Lower for some, especially late in the phase | Lighter evenings, protect your sleep |
| Training | Some women feel less powerful | Keep strength work, adjust intensity to how you feel |
| Sleep | Warmer body at night, lighter sleep for some | A cooler bedroom and an earlier wind-down |
| Work | Some women prefer quieter, focused tasks | Plan wrap-ups and detail work; book big pitches earlier when you can |
How long is the luteal phase?
Usually about 10 to 16 days, and for most women it stays fairly similar from cycle to cycle. When cycles differ in length, the difference mostly comes from the first half of the cycle, before ovulation.1
Why am I so hungry before my period?
Your body may use a little more energy at rest in the luteal phase. A 2020 review of studies found resting metabolism was higher in the luteal phase than in the follicular phase.2 Extra hunger in these days is biology, not a lack of willpower.
What should I eat in the luteal phase?
Regular, filling meals built on protein, fiber and slow carbohydrates, such as beans, oats, potatoes and whole grains. Nuts, seeds and leafy greens add magnesium. If you are hungrier, eating a bit more is reasonable.
Should I train differently?
Not necessarily. A 2020 meta-analysis found that performance differences across the cycle were small and varied between women.3 The best guide is how you feel, which is why Regime adjusts your workouts to what you log.
Why do I sleep worse in this phase?
After ovulation, body temperature rises by roughly 0.3 to 0.5 °C, and some women sleep more lightly in the days before their period.4 A cooler room and a calmer evening can help.
