The First Signs of Perimenopause: What French Women Know (That American Women Don't)

Let me tell you something I noticed when I first moved to America: the way women talk about perimenopause is completely different here.

In France, when my aunt Catherine turned forty-two and started noticing her cycles becoming unpredictable, she adjusted her evening meal timing and added more sardines to her lunch routine. She mentioned it once over Sunday lunch—“Je commence la transition”—and that was that. My mother did the same thing at forty-four. So did my aunt Isabelle at forty-six. None of them panicked. None of them Googled symptoms at 2am. None of them bought seventeen supplements from Instagram ads.

Here in America, I watch women experience the exact same early signs—an irregular period, disrupted sleep, unexpected mood dips—and immediately spiral into medical anxiety. They book hormone panels. They join Facebook groups with thousands of desperate posts. They treat perimenopause like a disease to diagnose rather than a transition to navigate.

The first signs of perimenopause are not a medical emergency. They are your body’s way of signaling that it’s time to adjust how you eat, move, and rest. French women understand this instinctively. We have a completely different framework for recognizing and responding to this transition—one that centers food, pleasure, and gradual adjustment instead of restriction, supplements, and panic.

This is exactly what I cover in my comprehensive guide to the French approach to perimenopause, but today I want to focus specifically on those first signs—what they actually are, when they appear, and what French women do when they notice them. Because if you can recognize perimenopause early and respond with the right foundation, you can avoid years of unnecessary struggle.

Why the American Approach to Early Perimenopause Fails

The American medical system treats perimenopause as a problem to solve. The wellness industry treats it as a condition to supplement. Both miss the fundamental truth: perimenopause is not a malfunction. It is a metabolic recalibration.

When American women first notice perimenopause signs—typically irregular periods, disturbed sleep, or mood changes—they immediately seek a diagnosis. They want to know their hormone levels down to the decimal point. They want to categorize their experience into a neat medical box. They want a pill or a protocol that will make everything go back to “normal.”

This approach has three fatal flaws.

First, it assumes perimenopause has a clear beginning that can be medically confirmed. It doesn’t. A study in The Journal of Clinical Endocrinology & Metabolism found that hormone levels during early perimenopause fluctuate wildly—often within the same week. One blood test means nothing. You can have “normal” estrogen on Tuesday and be in full perimenopause by Friday. French women don’t wait for lab confirmation. They trust their bodies.

Second, the American approach treats every symptom as something to eliminate rather than a signal to interpret. Brain fog isn’t a vitamin B12 deficiency to fix with a supplement—it’s your body telling you that your blood sugar regulation has changed and you need to eat differently. Night sweats aren’t a progesterone problem to solve with bioidentical hormones—they’re often a response to evening wine and cheese eaten too late. French women read the signals and adjust the inputs.

Third, and most damaging, the American perimenopause narrative is rooted in fear. Women are taught to expect the worst—debilitating hot flashes, severe mood disorders, uncontrollable weight gain. This creates a self-fulfilling prophecy. You brace for disaster, you restrict your eating “preventively,” you stress about every symptom, and the stress itself worsens everything.

French women expect perimenopause. We know it’s coming. We watched our mothers and grandmothers navigate it with minimal disruption. We don’t fear it because we have a roadmap: adjust your eating gradually, prioritize pleasure, trust your body’s intelligence.

What Are the First Signs of Perimenopause?

The very first signs of perimenopause are subtle. Most American women miss them entirely because they’re looking for dramatic symptoms—hot flashes, night sweats, severe mood swings. Those come later, in mid-to-late perimenopause. Early perimenopause is quieter.

Here’s what French women notice first, usually starting in the early-to-mid forties:

Cycle Changes (The True First Sign)

The earliest sign of perimenopause is almost always a shift in your menstrual cycle. Not the absence of periods—that’s late perimenopause—but subtle irregularity.

Your cycle might shorten from twenty-eight days to twenty-four. Or it might lengthen unpredictably—thirty-two days one month, twenty-six the next. The flow might become lighter or, conversely, heavier for a few months. You might skip a period entirely and then have two close together.

This irregularity is not a problem. It is your ovaries beginning their gradual retirement. French women expect this around age forty to forty-five. When my mother first noticed her cycles becoming unpredictable at forty-four, she simply started tracking them more carefully and adjusted her social plans accordingly. She didn’t panic. She didn’t run to the gynecologist for hormone tests. She recognized the signal for what it was: the beginning of a natural transition.

American women, by contrast, often don’t recognize irregular periods as perimenopause—especially if they’re still in their early forties. They attribute it to stress, or weight changes, or their birth control. They miss the opportunity to respond early with the right nutritional adjustments.

Sleep Disruption

The second sign French women notice is sleep changes. Not full-blown insomnia, but a shift in sleep quality.

You might start waking at 3am for no apparent reason. Or you might find it harder to fall asleep even when you’re tired. Or you might sleep through the night but wake feeling unrested. This happens because declining progesterone affects GABA production, your brain’s primary calming neurotransmitter.

My aunt Isabelle described it perfectly: “I would sleep, but I stopped resting.” She started eating dinner earlier—7pm instead of 8:30pm—and added magnesium-rich foods like almonds and dark chocolate to her afternoon routine. Within three weeks, her sleep improved. No melatonin. No Ambien. Just earlier meals and better food timing.

Sleep disruption in early perimenopause is almost always a blood sugar and meal timing issue, not a hormone problem requiring medication. But American women immediately reach for supplements or prescription sleep aids, which create dependency without addressing the root cause.

Mood Shifts (Subtle, Not Severe)

Early perimenopause mood changes are not the dramatic mood swings or anxiety that come in mid-perimenopause. They’re subtler: a shorter fuse than usual, unexpected tearfulness, a baseline feeling of being slightly “off.”

You might cry at a commercial that wouldn’t normally affect you. You might snap at your partner over something minor. You might feel a low-grade irritability that’s hard to pinpoint. This happens because estrogen fluctuations affect serotonin receptor sensitivity.

French women recognize this as a sign to add more omega-3 fats (sardines, mackerel, walnuts) and reduce inflammatory foods (processed oils, refined sugar). We don’t catastrophize it as depression requiring antidepressants. We adjust our plates.

Energy Dips (Especially Afternoon)

The fourth early sign is subtle energy changes. Not chronic fatigue—that comes later if perimenopause is mismanaged—but a noticeable afternoon slump that wasn’t there before.

You might feel energized in the morning but completely depleted by 3pm. Or you might need coffee to function when you previously didn’t. This is your body signaling that your blood sugar regulation has changed. The same breakfast that worked at thirty-five doesn’t work at forty-three.

When I started noticing this in my early forties, I stopped eating fruit smoothies for breakfast and switched to eggs with vegetables and good butter. My afternoon energy stabilized within days. Perimenopause changes your metabolic response to carbohydrates. French women adjust their plates accordingly.

Brain Fog (Mild, Intermittent)

Early perimenopause brain fog is not the severe cognitive disruption that comes in mid-perimenopause. It’s intermittent forgetfulness—you walk into a room and forget why, or you lose your train of thought mid-sentence, or you can’t recall a word you use regularly.

This happens because estrogen affects acetylcholine production, a neurotransmitter critical for memory and focus. French women respond by adding more choline-rich foods (eggs, liver pâté, salmon) and reducing blood sugar spikes that worsen cognitive function. I’ve written extensively about this in my article on perimenopause brain fog and the French foods that help.

Body Composition Changes (Not Weight Gain—Yet)

The earliest body change in perimenopause is not dramatic weight gain—that typically comes in mid-perimenopause if you don’t adjust your eating. It’s a subtle shift in where your body holds weight.

You might notice your waistline thickening slightly even if the scale hasn’t changed. Or you might feel “softer” even though you’re exercising the same amount. This is declining estrogen beginning to shift fat storage from hips and thighs to the abdomen.

This is not a reason to restrict calories or increase cardio. It is a signal to eat more protein and healthy fats, not less. French women eat more satisfying food during perimenopause, not less. I cover this in detail in my article on sudden weight gain in your 40s and perimenopause.

Can Perimenopause Start at 40?

Yes. Absolutely.

The average age for perimenopause to begin is forty-five, but about 5% of women experience early perimenopause starting in their late thirties, and many more notice the first signs at forty to forty-two. My mother began at forty-four. My aunt Catherine at forty-two. I started noticing subtle cycle changes at forty-one.

American doctors often dismiss perimenopause symptoms in women under forty-five, telling them they’re “too young” or that their symptoms must be stress or thyroid issues. This is medical gaslighting. If you are experiencing irregular periods, sleep changes, mood shifts, and energy dips in your late thirties or early forties, you are likely in early perimenopause—regardless of what your hormone panel says.

French gynecologists don’t require lab confirmation to acknowledge perimenopause. They trust women’s reported experiences. If you say you’re experiencing the signs, they believe you and recommend nutritional adjustments immediately.

The earlier you recognize perimenopause and respond appropriately, the smoother your transition will be. Waiting until symptoms become severe—until you’re experiencing daily hot flashes or significant weight gain or debilitating anxiety—makes everything harder.

What Are the Four Stages of Perimenopause?

Perimenopause is not a single event. It is a gradual transition that typically lasts four to eight years, moving through four distinct stages. French women don’t obsess over categorizing which stage they’re in—we simply adjust our eating and habits as symptoms evolve—but understanding the progression helps you recognize where you are and what to expect next.

Stage 1: Early Perimenopause (Ages 40-45, Typically 2-3 Years)

Early perimenopause is when your cycles first become irregular. You’re still having periods, but they’re less predictable. You might skip a month, then have two close together. Your PMS might intensify or change character.

Estrogen levels are still relatively normal most of the time, but progesterone begins declining. This creates the subtle symptoms I described earlier: sleep disruption, mild mood shifts, afternoon energy dips, intermittent brain fog.

What French women do in Stage 1: We adjust meal timing (earlier dinners), increase protein and healthy fats, reduce evening wine, add magnesium-rich foods, prioritize sleep. We don’t panic. We don’t eliminate food groups. We fine-tune.

Stage 2: Mid-Perimenopause (Ages 45-49, Typically 2-3 Years)

Mid-perimenopause is when symptoms peak. Estrogen fluctuates wildly—sometimes very high, sometimes very low, often within the same week. This creates more dramatic symptoms: hot flashes begin, night sweats appear, mood swings intensify, weight gain accelerates if eating hasn’t been adjusted.

Periods become very irregular—you might go two or three months without one, then have a heavy flow. Some months you ovulate, some months you don’t.

This is the stage where American women suffer most because they’ve been ignoring the early signs and haven’t built the nutritional foundation. French women who adjusted their eating in Stage 1 experience Stage 2 with minimal disruption.

What French women do in Stage 2: We double down on blood sugar stability (protein at every meal, no naked carbs, strategic carb timing), increase omega-3 fats, reduce inflammatory foods, manage stress with walking and social connection. We might add targeted foods like flaxseed or fermented soy. We still don’t restrict. We still eat pleasure foods. We just structure our plates more intentionally.

Stage 3: Late Perimenopause (Ages 48-52, Typically 1-2 Years)

Late perimenopause is when periods become very sporadic—you might have three or four per year. Estrogen levels are declining more consistently. Hot flashes and night sweats may continue but often begin stabilizing. Weight typically stabilizes if you’ve been eating appropriately.

What French women do in Stage 3: We continue the eating patterns established in Stage 2. We don’t change anything dramatically. We trust the foundation.

Stage 4: Menopause (Average Age 51-52)

Menopause is not a stage of perimenopause—it is the end of perimenopause. You are officially in menopause when you have gone twelve consecutive months without a period.

Interestingly, many women find that symptoms actually improve after menopause. The wild hormone fluctuations stop. Estrogen settles at a lower but stable level. If you’ve been eating well throughout perimenopause, postmenopause can feel calmer than mid-perimenopause.

French women don’t fear menopause. We see it as the completion of a natural process, not the beginning of decline.

How Do You Know If You Are Perimenopausal?

You don’t need a blood test to know if you’re in perimenopause. Blood tests during perimenopause are notoriously unreliable because hormone levels fluctuate so dramatically. You can test “normal” one day and be in full perimenopause the next week.

You know you’re in perimenopause if you are in your forties and experiencing some combination of irregular periods, sleep changes, mood shifts, energy dips, brain fog, and body composition changes—even if they’re subtle.

French women trust our bodies. We don’t need medical validation to respond to what we’re experiencing. If you’re experiencing the signs, you’re in perimenopause. Adjust your eating accordingly.

That said, if you have severe symptoms—debilitating hot flashes, significant depression or anxiety, very heavy bleeding, symptoms before age forty—see a doctor. Some women benefit from hormone replacement therapy or other medical interventions. The French approach is a foundation, not a replacement for medical care when needed.

What Are the Symptoms of Severe Perimenopause?

Most women experience mild to moderate perimenopause symptoms if they adjust their eating early. But some women—about 20-25%—experience severe perimenopause that significantly disrupts daily life.

Severe perimenopause symptoms include:

Hot flashes multiple times per day that interfere with work or sleep
Night sweats so intense you need to change clothes or sheets
Severe mood disruption: depression, anxiety, rage that feels unmanageable
Debilitating brain fog that affects your ability to work or function
Extremely heavy bleeding that requires changing pads or tampons every hour
Complete sleep disruption despite good sleep hygiene and meal timing
Significant weight gain (15-20+ pounds) despite eating well

If you’re experiencing severe symptoms, see a doctor. French women are not anti-medical intervention. We simply believe food and habits should be the foundation, with medical support added when needed.

Some women genuinely need hormone replacement therapy. Some women need progesterone support for heavy bleeding. Some women need short-term antidepressants for severe mood symptoms. There is no shame in this.

What French women don’t do is reach for medical intervention first, before trying the nutritional foundation. We also don’t suffer in silence out of some misguided belief that perimenopause “should” be easy. We’re pragmatic. We do what works.

What Are Odd Signs of Perimenopause?

Perimenopause affects every system in your body because estrogen receptors exist everywhere—in your brain, bones, skin, hair, joints, digestive system, immune system. This creates some unexpected symptoms that American women often don’t associate with perimenopause:

Weird Perimenopause Symptoms French Women Recognize

Gum sensitivity and dental changes. Your gums might become more sensitive, bleed more easily, or your teeth might feel different. This is declining estrogen affecting oral tissue.

Joint pain and stiffness, especially in the hands and knees. My aunt Catherine developed what she thought was early arthritis at forty-four. It was perimenopause. When she increased her omega-3 intake and reduced inflammatory oils, it improved significantly.

Digestive changes. You might develop bloating or constipation you never had before, or foods you previously tolerated might suddenly cause issues. This is changing gut motility and microbiome shifts.

Skin changes beyond dryness. Your skin might become more reactive, develop rashes, or heal more slowly from minor cuts. Estrogen affects skin barrier function.

Heightened sense of smell. Some women become hypersensitive to perfumes, cleaning products, or food smells. This is a neurological effect of fluctuating estrogen.

Electric shock sensations under the skin or in the head. This sounds alarming but is a known perimenopause symptom caused by estrogen’s effect on the nervous system.

Thinning hair or changes in hair texture. Your hair might become finer, or you might notice more shedding.

Changes in body odor. You might notice your sweat smells different or stronger. This is hormonal shifts affecting sebaceous glands.

Burning mouth or metallic taste. Some women experience strange taste sensations or a burning feeling on the tongue.

French women don’t panic about these odd symptoms. We recognize them as part of the hormonal recalibration and respond with anti-inflammatory eating, good fats, and mineral-rich foods. We don’t rush to specialists for every symptom. We trust that supporting our bodies nutritionally addresses most of these issues.

Why Don’t Japanese Women Get Menopause Symptoms?

This is one of the most interesting cross-cultural perimenopause questions, and the answer reveals a lot about the power of food.

Japanese women do experience perimenopause—their ovaries decline just like everyone else’s—but they report significantly fewer and less severe symptoms than Western women. A landmark study in Menopause: The Journal of The North American Menopause Society found that only 10-15% of Japanese women report hot flashes, compared to 70-80% of American women.

The difference is not genetic. When Japanese women adopt Western diets, their perimenopause symptom rates match Western women’s. The difference is entirely food and lifestyle.

Here’s what Japanese women eat that Americans don’t:

High phytoestrogen intake. Japanese women consume 25-50mg of soy isoflavones daily (from tofu, miso, edamame, natto), compared to less than 3mg for most American women. Phytoestrogens are plant compounds that weakly bind to estrogen receptors, providing gentle hormone support during the transition.

Fermented foods daily. Miso, natto, pickled vegetables. Fermentation enhances the bioavailability of isoflavones and supports gut health, which is critical for hormone metabolism.

High omega-3 intake from fish. Japanese women eat fish multiple times per week, providing anti-inflammatory omega-3 fats that stabilize mood and reduce hot flash frequency.

Low sugar and processed food intake. Traditional Japanese eating is built around whole foods—fish, vegetables, rice, soy, seaweed. Very little processed food, very little refined sugar. This keeps inflammation low and blood sugar stable.

Cultural expectation of minimal symptoms. Japanese women don’t expect perimenopause to be debilitating. The cultural narrative is that it’s a natural, manageable transition. This reduces the stress and fear that amplify symptoms.

This is exactly the French approach. We don’t eat as much soy as Japanese women, but we eat fermented foods (cheese, yogurt), fish, whole foods, minimal processed food. We expect perimenopause to be manageable. We use food as our primary tool. And, like Japanese women, French women experience perimenopause with significantly less drama than American women.

The lesson: your diet and your expectations shape your perimenopause experience more than your genes do.

What French Women DON’T Do During Perimenopause

The French approach to perimenopause is as much about what we don’t do as what we do.

We Don’t Take Fifteen Supplements

American women facing perimenopause are targeted by an entire supplement industry promising to “balance hormones” with proprietary blends of maca, black cohosh, dong quai, red clover, ashwagandha, DIM, vitex, and seventeen other compounds.

French women don’t buy this. We get our nutrients from food. If we supplement at all, it’s with basics: magnesium (if sleep is disrupted), omega-3 (if we’re not eating enough fish), vitamin D (if we live in northern climates). That’s it.

Most perimenopause supplements are expensive placebos. The few that have research backing—like black cohosh or soy isoflavones—work because they provide concentrated versions of compounds you could get from food. We’d rather eat the food.

We Don’t Eliminate Food Groups

American perimenopause advice is full of restriction: eliminate gluten, eliminate dairy, eliminate sugar, eliminate carbs, eliminate nightshades, eliminate caffeine, eliminate alcohol completely. The list of “forbidden” foods grows longer every year.

French women don’t eliminate food groups. We eat bread. We eat cheese. We eat chocolate. We drink wine. We simply structure our plates intelligently—protein and fat first, carbs strategic, portions appropriate, timing intentional.

Restriction creates stress, and stress worsens perimenopause symptoms. We prioritize pleasure because pleasure reduces cortisol, and cortisol management is critical during perimenopause.

We Don’t Panic-Google at 2am

When American women experience a new perimenopause symptom, they immediately Google it, fall into a rabbit hole of worst-case scenarios, join Facebook groups where everyone is sharing their suffering, and convince themselves they’re experiencing the worst perimenopause in history.

French women call our mothers or aunts. We ask, “Did you experience this?” They say, “Yes, I ate more fish and it improved.” We eat more fish. We move on.

The stories you consume about perimenopause shape your experience. If you surround yourself with narratives of suffering, you will suffer more. If you surround yourself with narratives of natural, manageable transition, your transition will be more manageable.

We Don’t Wait for Medical Permission to Adjust Our Eating

American women want their doctor to tell them what to eat. They wait for lab results to “confirm” perimenopause before making any changes. They need official validation that something is wrong before they’ll adjust their plates.

French women trust our bodies. If we notice the first signs of perimenopause, we adjust our eating immediately. We don’t wait for hormone panels. We don’t need a doctor’s prescription to eat more protein or have dinner earlier. We take responsibility for our own bodies.

Your Practical Framework: What to Do When You Notice the First Signs

If you’re reading this and recognizing yourself in the early perimenopause signs, here’s your roadmap. This is exactly what French women do when we first notice the transition beginning.

Week 1: Stabilize Blood Sugar

Your only focus this first week is blood sugar stability. This single change will improve sleep, mood, energy, and brain fog faster than anything else.

Every meal must contain protein and fat. No naked carbs. No fruit smoothies. No toast with jam. No pasta with marinara. Every time you eat, you eat protein (eggs, fish, meat, Greek yogurt, cheese) and healthy fat (butter, olive oil, nuts, avocado).

Have dinner by 7pm if possible, 8pm at the latest. Earlier eating improves sleep dramatically.

If you snack, snack on protein and fat. Cheese and almonds. Hard-boiled eggs. Full-fat yogurt. Not crackers. Not granola bars. Not fruit.

Notice what happens. Most women notice better sleep within three to five days. Energy improves within a week. Don’t move to Week 2 until blood sugar stability feels natural.

Week 2: Add Anti-Inflammatory Fats

Once your blood sugar is stable, add specific fats that reduce inflammation and support hormone production.

Eat fatty fish twice per week minimum. Sardines, mackerel, salmon, herring. These provide omega-3 fats that stabilize mood and reduce hot flash frequency.

Cook with good butter or olive oil. Stop using processed seed oils (canola, soybean, corn, “vegetable” oil). These oils are inflammatory and worsen perimenopause symptoms.

Add nuts and seeds. Walnuts, almonds, ground flaxseed. These provide magnesium, omega-3s, and lignans that support hormone metabolism.

Eat egg yolks. The yolk contains choline, which supports brain function and reduces brain fog.

Week 3: Structure Pleasure

Identify your three essential pleasure foods. For me, it’s dark chocolate, good cheese, and wine. For you, it might be sourdough bread, gelato, and pastries. Whatever they are, name them.

Create structure around them. I have dark chocolate after lunch. I have cheese with dinner. I have wine with Saturday dinner, not every night. This is not restriction—it’s intentional pleasure.

Stop eating pleasure foods standing up, distracted, or in the car. Sit down. Use a real plate. Pay attention. Savor. This increases satisfaction and reduces the urge to overeat.

Notice what happens. Most women find that structured pleasure reduces cravings and emotional eating better than restriction ever did.

Week 4: Adjust Carbs Strategically

Eat most of your carbs at lunch, not dinner. Your insulin sensitivity is higher during the day. Evening carbs disrupt sleep and worsen night sweats.

Choose complex carbs over refined. Sourdough over white bread. Potatoes over pasta. Rice over crackers.

Don’t eliminate carbs. You need them for serotonin production, sleep, and mood regulation. You just need to time them appropriately.

Beyond Week 4: Fine-Tune and Maintain

Once you’ve built this foundation, you fine-tune based on your specific symptoms:

If sleep is still disrupted: Increase magnesium-rich foods (almonds, dark chocolate, spinach), have dinner even earlier, reduce or eliminate evening alcohol.
If mood is unstable: Increase omega-3 fats, reduce inflammatory oils, ensure you’re eating enough protein.
If brain fog persists: Add more choline-rich foods (eggs, salmon, liver pâté), stabilize blood sugar even more carefully. Read my article on perimenopause brain fog for detailed strategies.
If weight is shifting: Increase protein, reduce evening carbs, ensure you’re not under-eating (which slows metabolism). See my article on weight gain in your 40s.
If anxiety or mood swings are significant: Read my detailed guide on perimenopause anxiety and the French approach.

This is not a diet. This is a recalibration. You’re not restricting. You’re not eliminating. You’re adjusting your eating to match your changing physiology. French women do this intuitively because we watched our mothers do it. You’re learning it explicitly, but the principle is the same: trust your body, adjust your plate, prioritize pleasure.

The Bigger Picture: Perimenopause as Part of Your Life, Not a Medical Crisis

Perimenopause is a four-to-eight-year transition. It is not a brief inconvenience you power through. It is not a medical crisis you solve with pills. It is a natural recalibration of your entire endocrine system that requires you to adjust how you eat, move, and rest.

French women see perimenopause as part of the arc of our lives. We enter it in our forties. We exit it in our early fifties. We adjust our eating and habits accordingly. We don’t fight it. We don’t fear it. We don’t try to make our forty-five-year-old body behave like our thirty-year-old body.

Perimenopause is your body asking you to eat like an adult woman in her forties, not like a college student or a fitness influencer. It’s asking you to prioritize protein, healthy fats, earlier dinners, consistent sleep, pleasure without chaos. These are not punishments. They are the foundation of feeling good in your body during this transition and beyond.

If you’re in early perimenopause right now—if you’re noticing those first subtle signs—you have an extraordinary opportunity. You can build the nutritional foundation that makes mid-perimenopause manageable instead of miserable. You can avoid the years of struggle that come from ignoring the signals or responding with restriction.

The French approach to perimenopause is not complicated. It doesn’t require expensive supplements or hormone panels or elimination diets. It requires you to eat real food, structure pleasure, trust your body’s signals, and adjust gradually as symptoms evolve.

That’s it. That’s the entire framework. Everything else is details.

If you’re experiencing sudden weight gain, brain fog, anxiety or mood swings, I’ve written detailed articles on each of these specific symptoms and exactly how French women address them with food. Start with the foundation here, then go deeper on whatever symptom is affecting you most.

A Medical Note

Perimenopause is a natural transition, but it is also a significant medical and hormonal change. If you are experiencing severe symptoms—debilitating hot flashes, significant depression or anxiety, very heavy bleeding, or symptoms that interfere with your ability to work or live—please see a doctor.

The French approach I’ve described is a nutritional and lifestyle foundation. It is not a replacement for medical care when medical care is needed. Some women genuinely benefit from hormone replacement therapy, progesterone support, or other interventions. There is no shame in seeking medical help. French women are pragmatic—we do what works.

That said, food and habits should always be the foundation, whether you pursue medical intervention or not. No amount of hormone replacement will compensate for chronic blood sugar dysregulation, inflammatory eating, or sleep deprivation. Build the foundation first. Add medical support if needed.

Frequently Asked Questions

What are the first signs of perimenopause?

The first signs of perimenopause are typically irregular periods, sleep changes, and mood shifts. These usually begin in your mid-forties but can start as early as your late thirties. French women recognize these as a natural transition, not a medical crisis, and respond with gradual adjustments to eating and habits rather than panic or supplements.

What are the four stages of perimenopause?

The four stages of perimenopause are: Early perimenopause (irregular cycles begin), mid-perimenopause (symptoms peak with wild hormone fluctuations), late perimenopause (periods very sporadic), and menopause (twelve months without a period). French women don’t obsess over categorizing stages—we simply adjust our eating and habits as symptoms evolve.

Can perimenopause start at 40?

Yes, absolutely. While the average age for perimenopause to begin is forty-five, about 5% of women experience early perimenopause in their late thirties, and many begin noticing changes at forty to forty-two. French women expect this transition and prepare with food adjustments, not fear or medical intervention unless symptoms are severe.

Why don’t Japanese women get menopause symptoms?

Japanese women consume high amounts of soy (providing phytoestrogens), fermented foods, and fish—similar to the French Mediterranean-influenced diet. Both cultures prioritize whole foods, minimal processed food, and have cultural expectations that perimenopause is manageable. When Japanese women adopt Western diets, their symptom rates match Western women’s, proving the difference is food and lifestyle, not genetics.
