Your body changes throughout your menstrual cycle and those changes can affect your energy, hunger, cravings, mood, sleep, and recovery.
…Does that mean you need a completely different nutrition and training plan every week?
Not exactly.
Research shows that hormones and nutrient-related markers can shift across the menstrual cycle, especially during the luteal phase. In one study, researchers tracked healthy women across the menstrual cycle and measured more than 400 blood and urine markers. They found that many nutrients and metabolic markers changed depending on cycle phase, including amino acids, vitamins, hormones, and mood-related compounds.
That may help explain why some women notice more cravings, fatigue, mood changes, or harder recovery before their period. This does not mean every woman needs a completely different training or nutrition plan each week. The best approach is to use your cycle, symptoms, and recovery trends as feedback, then adjust food, training, and recovery support accordingly.
For perimenopausal or post-menopausal women, the same principles still apply, but instead of tracking a predictable monthly cycle, the focus shifts toward symptoms, recovery, muscle, bone, sleep, and metabolic health.
Breaking down each cycle phase
Menstrual phase: your body is resetting
This is when bleeding occurs. Some women feel tired, crampy, lower energy, or less motivated.
Focus on: hydration, protein, iron-rich foods if bleeding is heavy, gentle movement if needed, and adequate sleep.
Follicular phase: often a higher-energy window
After your period, estrogen begins to rise. Many women feel better energy, mood, motivation, and training performance here.
Focus on: consistent meals, solid workout fueling, strength training, and building momentum with habits.
Ovulation: a short hormonal shift
Around ovulation, hormones like LH and FSH rise. Some women notice better energy or strength, while others notice bloating, mild discomfort, or appetite changes.
Focus on: protein, colorful plants, hydration, and B-vitamin-rich foods like salmon, chickpeas, poultry, potatoes, bananas, and sunflower seeds.
Luteal phase: the “higher support” phase
This is the phase after ovulation and before your period. It is often when PMS symptoms show up: cravings, mood changes, bloating, fatigue, disrupted sleep, or harder recovery.
Focus on: protein at every meal, enough total food, B6-rich foods, fiber-rich carbs, cruciferous vegetables, hydration, and sleep.
What to do during the week before your period
You do not need a complicated cycle-syncing plan and all of these areas of focus are important all of the time, but the week before your period, your body has higher nutrient and recovery needs and can be further supported by making these a priority:
1. During the luteal phase, amino acid needs may be higher. Eat protein at every meal.
Protein supports muscle, recovery, blood sugar stability, and satiety.
Aim for 25–35g of protein per meal, or your personalized target.
Examples:
● Eggs or egg whites
● Chicken or turkey
● Salmon or tuna
● Greek yogurt or cottage cheese
● Lean beef
● Tofu, tempeh, or edamame
● Protein smoothie
● Beans or lentils paired with another protein source
2. Don’t fight cravings by restricting harder.
That often backfires.
Your body may naturally burn slightly more energy in the luteal phase, and hunger can increase.
If you respond by skipping meals, cutting carbs, or trying to “be extra good,” cravings and mood swings may get worse.
Instead, build meals around:
● Protein
● Fiber-rich carbs
● Colorful produce
● Healthy fats
● Enough total calories
This is especially important if you are training hard.
3. Add one B6-rich food daily
Vitamin B6 helps support neurotransmitters involved in mood, including serotonin. Around the premenstrual window, this can be a helpful nutrient to prioritize.
B6-rich foods include:
● Salmon
● Tuna
● Chicken
● Turkey
● Chickpeas
● Potatoes
● Bananas
● Sunflower seeds
4. Support antioxidants with cruciferous vegetables
Cruciferous vegetables support your body’s antioxidant and detoxification systems.
Try adding one serving per day of:
● Broccoli
● Cauliflower
● Brussels sprouts
● Kale
● Cabbage
● Arugula
Simple options: roasted broccoli with dinner, cauliflower rice in a bowl, kale in a smoothie, or arugula added to eggs or a salad.
5. Keep training, but adjust expectations
You do not need to stop lifting or completely change your workouts during the luteal phase.
In fact, research suggests that muscle protein synthesis (your body’s ability to repair and build muscle after resistance training), may not differ meaningfully between the follicular and luteal phases. This means your muscles can still respond well to training throughout your cycle.
However, you may feel different.
During the week before your period, it may help to:
● Take a longer warm-up
● Add more rest between sets
● Reduce intensity slightly if needed
● Prioritize carbs around workouts
● Focus more on technique
● Get extra sleep
● Avoid judging your progress based on one rough training day
What about perimenopause?
Perimenopause is different because your cycle may become less predictable.
You may still have periods, but they can become irregular, heavier, lighter, closer together, farther apart, or skipped. Hormones like estrogen and progesterone fluctuate more dramatically, which can contribute to symptoms like poor sleep, hot flashes, mood changes, cravings, brain fog, joint aches, and changes in body composition.
So instead of asking, “What cycle phase am I in?” a better question is:
“What patterns am I noticing, and what support does my body need right now?”
For perimenopausal women, the most helpful things to track are often:
● Sleep quality
● Hot flashes or night sweats
● Hunger and cravings
● Mood and stress resilience
● Training performance
● Recovery and soreness
● Joint pain
● Energy
● Changes in cycle length or flow
The goal is not to micromanage every hormone shift, but to build a strong foundation that helps your body handle those shifts better.
What about post-menopause?
After menopause, the focus changes again. You no longer have the same monthly cycle, but lower estrogen levels can influence muscle, bone, body composition, cardiovascular health, sleep, and insulin sensitivity.
This is where the “big rocks” matter most:
- Protein Becomes Even More Important
- Strength Training Is Non-Negotiable
- Avoid Chronic Under-Eating
- Support Bone Health
- Pay Attention to Sleep
The bottom line
Your hormones matter, but they do not require a completely different plan every week.
For cycling women, your menstrual cycle can give you clues about when you may need more fuel, more recovery, more protein, or more flexibility.
For perimenopausal women, the pattern may be less predictable, so symptom tracking often becomes more useful than cycle tracking.
For post-menopausal women, the focus shifts toward protecting muscle, bone, metabolism, sleep, and long-term strength.
Your body is always giving you feedback.
The more you understand that feedback, the better you can support your health, training, and long-term results.
