How to Eat for Your Cycle: Four Phases
Learn how to eat for all phases of your menstrual cycle to help your body be as healthy as possible. Cycling women can use nutrition to help support hormone balance and ease of symptoms throughout the month.
Menstrual Cycle Meaning
For cycling women of all ages, it’s important to be aware of the ways that nutrition and food choices can support our hormones.
Our menstrual cycles can be a quick measure of our overall health. The relative ease and regularity of your menstrual cycle is an amazing piece of information that gives you insight about your overall health. In fact, some health professionals consider it to be the 5th vital sign.
The menstrual cycle is so important because it indicates whether or not a woman is healthy and safe enough to reproduce. Reproduction is not essential to survival, so it is often the first system to “shut off” in times of illness or stress.
This ability to stop menstruating is the body’s protection mechanism not to get pregnant in a less than optimal environment. Historically, this often occurred due to famine or other life-threatening circumstances. Today, a lack of a normal cycle occurs due to stress, imbalanced hormones, or lack of nourishment.
Most women between the ages of 12-50 have between 10-12 cycles a year. Menstrual cycles should generally be between 28-35 days, though this number may vary slightly. As long as your cycle is normal for you and is consistent, that is a good sign.
As always, however, it’s important to consult your healthcare provider if you have changes in your cycle or if you miss more than a couple of cycles and you aren’t pregnant.
It is normal to have some variations in our cycles. Even the season can cause changes. Certainly, one’s age, stage of life, and level of stress can also cause changes.
Overview of Four Menstrual Phases
We often think of menstruation as the main event of a cycle, but there are actually four phases in a cycle. The two main parts are the follicular and luteal phases, but they can be broken up further into the menstrual, follicular, ovulatory, and luteal phases.
One way to monitor your changes from phase to phase is to keep a journal of how you are feeling each day and what food cravings or mood changes you have.
Here is a more details description of the four parts of the female menstrual cycle. Note that there will be some variation in the timing based on each individual female.
Menstrual Phase (Days 1-5)
The first day of bleeding marks the first day of your entire cycle. Menstruation occurs from days 1-5, though your specific period length may look different. Anywhere from 2-7 days is considered normal, though most women bleed between 3-5 days.
During the menstrual phase, you are shedding your uterine lining from the previous cycle. All hormones are low for the first few days, with estrogen and FSH (follicle stimulating hormone) begin to rise towards the end. Your body is also busy maturing several eggs for ovulation.
See below for the best foods to eat on your period.
Follicular Phase (Days 6-15)
After you stop bleeding, you move into your follicular phase, which occurs from days 6-15 (or from the last day of bleeding to ovulation). During this time, your body selects one dominant follicle to nurture and grow in preparation for ovulation.
I’ve include a list below of foods to eat during the follicular phase.
Estrogen rules this part of your cycle, along with luteinizing hormone to trigger ovulation. The end of the follicular phase is marked by ovulation, when the follicle bursts and releases an egg ready for fertilization.
Ovulatory Phase (Days 16-21)
Immediately after ovulation, your body is prepared for a fertilized egg to implant itself in your uterus. The ovulatory phase lasts from the end of ovulation to the luteal phase, roughly days 16-21.
During this luteal phase, progesterone rises, prompting the continued growth of a nutrient-dense uterine lining ready for implantation. The dominant follicle, now referred to as the corpus luteum, is primarily responsible for secreting the progesterone that will ensure a successful pregnancy if the egg has been fertilized.
See below for what to eat when you’re ovulating.
Luteal Phase (Days 21-30)
From days 21-30, or the week before your next period, your body has gotten the message that is is not pregnant (if the egg is not fertilized). Thus, it begins preparing to shed the uterine lining and repeat the cycle again. As the corpus luteum begins dying, it takes progesterone with it. Estrogen remains lower as well.
This phase is when many women experience premenstrual syndrome, or PMS. PMS often occurs due to low progesterone levels, usually a result of poor follicle creation and/or unsuccessful ovulation (meaning the egg was not healthy enough or you did not ovulate at all.)
Your luteal phase ends with the first day of real bleeding, marking the first day of your next cycle. See below for the best luteal phase foods.
How to Eat for Each Phase
Your diet is a great way to optimize each phase of your cycle. Not only do you get to target potential symptoms with key nutrients, but your cycle is a built-in way to rotate your foods and ensure variety in your diet.
Here are some tips for a Menstrual Cycle Diet to support balanced hormones and your optimal energy and well-being.
Don’t worry if you can’t incorporate specific foods during each phase, but you might want to test if cycle syncing at least a few meals helps manage any unpleasant symptoms that you experience.
Foods for Menstrual Phase (Days 1-5)
Your menstrual phase is a time to rest and replenish. Your body is undergoing a controlled inflammatory response to shed your uterine lining, so nourishing yourself with nutrient-dense, anti-inflammatory foods will help support you at this time.
Due to blood loss, iron-containing foods are the most important. Most women also need an iron supplement (see my recommendations of supplements for women of child-bearing age).
- A sample meal for your menstrual phase could include Instant Pot Sweet Potato & Beef Chili and a salad filled with iron-rich spinach, high-antioxidant berries, and healthy fats like sliced avocado and olive oil.
- Steer clear of inflammatory sugary foods, but you can nourish your magnesium levels and your mood with a few daily squares of dark chocolate or my recipe for Healthy Hot Chocolate.
- Other foods that are supportive of the menstrual cycle include: buckwheat, dulse, kelp, blackberries, blueberries, watermelon, kidney beans, flax seeds, pork, shellfish, miso, and sea salt to replenish minerals. You can try adding an Adrenal Cocktail to improve your electrolyte levels too. Beet Juice contains plant-based iron and minerals.
Foods for the Follicular Phase (Days 6-15)
A lot of women feel best during their follicular phase when the body’s fertility efforts are more behind the scenes. Enjoy a normal balanced diet during this phase, incorporating plenty of nourishing foods to provide nutrients to a maturing follicle.
Play around with new recipes and foods during this easy phase of your cycle!
- A sample meal for your follicular phase could include nutrient-dense foods like oats, artichoke, salads, lentils, carrots, eggs, broccoli, fruit, and nuts. You could also add a Green Vegetable Juice to your diet to help add extra micronutrients.
- Some women find themselves prone to dehydration during their follicular phase due to the high levels of hormones, so incorporate more mineral-rich sea salt and water during this time (try my recipe for Cucumber Ginger Lemon Water or homemade Celery Juice).
Foods for the Ovulatory Phase (Days 16-21)
During your ovulatory and luteal phases, you want to start supporting your detoxification pathways to make it easy to metabolize and eliminate the used hormones from your follicular phase.
Focus on liver-loving foods like cruciferous vegetables, antioxidant-rich berries, and protein. Incorporate plenty of fiber to ensure you’re able to eliminate properly.
You may consider eating easily digestible foods since some women can start to have digestive issues during this phase.
- A sample meal for your luteal phase could include a pureed soup, which is typically easy to digest. A dairy-free broccoli pureed soup is a great option (see all of my dairy-free soup recipes). Or, try my Liver Detox Smoothie that is very nourishing and naturally detoxifying.
- You can also try eating more foods with natural probiotics such as sauerkraut and coconut yogurt to help with any digestive issues during the luteal phase.
- Other foods to eat during ovulation include: quinoa, melons, strawberries, almonds, sunflowers, salmon, tuna, asparagus, spinach, and tomatoes. Try my recipe for an easy Costco Quinoa Salad.
- Try adding some homemade broccoli sprouts to also help with your body’s natural detox pathways.
Foods for the Luteal Phase (Days 21-30)
To help stave off cramps, headaches, and difficulty sleeping during the luteal phase of your menstrual cycle, you should definitely include magnesium-rich foods while continuing to support your detox pathways.
Foods high in magnesium include nuts and seeds, leafy greens, avocado, chocolate, and bananas. If you have trouble with allergies during this time, try my tips for how to reduce histamine naturally.
- A sample meal for your premenstrual phase may include a soothing smoothie made with magnesium-rich banana, cacao powder, almond butter, and avocado. Toss in some cruciferous kale or cauliflower for extra detox support. Adding in collagen peptides should supply you with the amino acids necessary to support great sleep.
- Other foods to support the luteal phase include: cabbage, cauliflower, cucumbers, apples, peaches, pears, chickpeas, pine nuts, sunflower seeds, beef, turkey, cod, halibut, and peppermint. Try adding a Turmeric Shot to your diet to help reduce inflammation.
- Avoid too many added sugars which may contribute to premenstrual migraines and mood swings. See my list of the best no-sugar foods.
Seed cycling, or the practice of ingesting different seeds for the two major phases of your cycle, can help support hormone balance for some women. However, there has never been a large-scale study performed to investigate the benefits of seed cycling.
Not all women will need to take iron during their menstruation phase, but most women do need it. You should always test your ferritin levels before taking an iron supplement (learn more about which lab tests women should get).
It’s important to consult your doctor to determine what ferritin level is optimal for you. Ferritin is different than iron; it is a protein that controls the capacity of your body to store and release iron as needed. If ferritin levels are low, you won’t be able to store or release adequate iron into your bloodstream.
Ferritin is important for many different mechanisms in your body. Iron is required for adequate T3 and T4 production and utilization. If the body senses low iron storage from low ferritin levels, it won’t produce adequate thyroid hormones. Low ferritin levels can also lead to low energy, weakness, lightheadedness, and brittle hair and nails.
If you have the above symptoms, or if you have especially heavy periods, it’s wise to get your ferritin levels checked. Learn more about the reasons why you might always be tired.
There is no one-size-fits-all hormone protocol. Every woman is different and should get individual advice from a qualified practitioner.
Having an adequate nutrient intake with a varied, whole foods diet and supplementation is the first step in balancing your hormones. Learn more about how to reverse estrogen dominance naturally. You Might also like my article on the best supplements to balance hormones.
