Ack! I need chocolate! The science of PMS food cravings

Ack! I need chocolate! The science of PMS food cravings

Premenstrual food cravings are the punchline of endless jokes. Like most good jokes, they're funny because they're true.

Certain parts of a woman's menstrual cycle do seem to go hand in hand with the desire for chocolate ice cream and potato chips. I hear about this every day from my OBGYN patients.

Researchers have studied food cravings for years; one of the most cited studies dates back to 1953. Scientists – and lots of others – want to know who has food cravings and why, what they crave, when they crave it and how to minimize the cravings. Here's what the research has found.

Craving and eating before a period

Food cravings are just one of the many symptoms of premenstrual syndrome, also known as PMS. PMS is likely caused by hormonal fluctuations and how they affect chemical messengers in the brain called neurotransmitters. Its symptoms are exclusive to the second half of the menstrual cycle. This luteal phase of the cycle starts with the release of the egg at ovulation and ends when a period begins. The symptoms usually resolve around the third or fourth day of menstruation.




Researchers have documented more than 150 different PMS symptoms in studies, ranging from physical to emotional to behavioral to cognitive. Food cravings are up there with the most commonly reported behavioral PMS symptoms, along with mood swings, irritability, anxiety and tension, and sad or depressed mood.

A woman doesn't need an official diagnosis of PMS to report hankering for sweets and chocolates, though. Eighty-five percent of women have some sort of perceptible premenstrual symptoms, while only somewhere in the range of 20% to 40% of all women meet the diagnostic criteria for PMS. Researchers find that cravings can occur during that premenstrual time period in normal, healthy individuals without a diagnosis of PMS or other disorder. In fact, one study showed that 97% of all women had previously experienced food cravings – independent of their menstrual cycle.

Research data confirm women tend to eat more during the luteal phase of the menstrual cycle, compared to the follicular phase that leads up to ovulation. With or without the diagnosis of PMS, this increased food intake can be as high as 500 extra calories per day.

What foods are women reaching for? Carbs and fats and sweets. No surprise there. The most commonly reported food craving is chocolate, likely because it's a pleasantly sweet combination of carbs and fat.

And although the existence of any craving is similar across women with and without PMS, the craving itself may differ depending on if you have the diagnosis of PMS. In one study, women without PMS increased their intake of energy and fat, while women with PMS showed increase in total energy and all macronutrients.

What causes food cravings?

Researchers aren't exactly sure where these food cravings come from, but there are several leading theories.


One idea is that women are unconsciously using food as a pharmacological therapy. Many studies show that women in their luteal phase crave more carbohydrates compared to during their follicular phase. Eating carbs turns up levels of serotonin, a neurotransmitter in the central nervous system, which contributes to a general sense of well-being and happiness. By increasing carb intake, women may be self-medicating with food to cause that serotonin bump in order to feel better. In one study, when researchers increased serotonin neurotransmission in the brain, either through diet or drugs, people's food intake and mood went back to normal.

Another possible explanation for food cravings suggests that women intentionally turn to food for physical and psychological comfort. Food can play a sensory role, eliminating any uncomfortable feeling of hunger while tasting good and feeling pleasant to eat. Researchers find that "thinking" of a really tasty food is the most common provocation for wanting to consume it and that cravings are not solely hunger driven. Women also usually reported specific triggers for thinking of comforting food, like boredom or stress, further promoting the idea that the comfort of food helps mitigate unpleasant feelings – as one might experience with PMS.

Other researchers suggest that these food cravings are regulated by hormones. Scientists have observed that women tend to eat more when estrogen levels are low and progesterone levels are high – as occurs during the luteal phase. The reverse pattern is seen in rats during the follicular phase, when estrogen levels are high and progesterone levels are low. The fact that progesterone-only forms of contraception like Depo Provera are associated with weight gain, likely due to increased appetite, supports this theory as well.

How can you get rid of monthly cravings?

My general advice to women: be knowledgeable about your own body and how it changes in response to your monthly cycle. Your experience is different than your best friend's. Being in touch with your symptoms can help you acknowledge that they are normal for you at this point in time instead of worrying whether they're weird. If you feel unsure, ask your gynecologist.


Lifestyle changes can help balance and minimize unwanted symptoms related to your menstrual cycle. Things to try include regular exercise, relaxation and stress reduction techniques such as breathing exercises, yoga, meditation, massage, self-hypnosis and regular, good sleep.

Cognitive behavioral therapy and biofeedback may be options. They usually require support of a therapist or counselor to be most effective.

And you can optimize your diet to fight cravings:

  • Choose complex carbohydrates, including whole grains, brown rice, barley, beans and lentils. Choose whole wheat over white flour.
  • Reduce fat, salt and sugar – all of which can leave you craving more.
  • Minimize or avoid caffeine and alcohol.
  • Eat more calcium-rich foods, including green leafy vegetables and dairy. One study showed women who consumed milk, cheese and yogurt had less abdominal bloating, cramps, appetite and cravings for some foods, possibly because the calcium they contain helped reverse an imbalance of feel-good serotonin. Women who are sensitive to dairy can take a calcium supplement of 1200 mg daily.
  • Try magnesium supplements. This mineral can help reduce water retention and bloating, breast tenderness and mood symptoms.
  • Vitamin B6 (50 mg daily), in addition to magnesium, may have some benefit as well.
  • Vitamin E (150-300 IU daily) may be helpful to reduce cravings.

When food cravings are part of a PMS diagnosis, treatment for premenstrual syndrome in general may help minimize them.

Three women, three MS journeys: How multiple sclerosis looks different for everyone

Gina, Nathalie and Helga share their reactions to being diagnosed with MS and how they stay informed and positive in the face of ever-changing symptoms.

Helga, Nathalie and Gina all have MS, and their experiences show how differently the disease can manifest.

True

It’s been 155 years since neurologist Jean-Martin Charcot gave the first lecture on a mysterious progressive illness he called “multiple sclerosis.” Since then, we’ve learned a lot. We know MS causes the immune system to attack healthy tissue, including damaging the brain and spinal cord. Resulting symptoms can be debilitating and include fatigue, blurred vision, memory problems and weakness. Huge advancements in our understanding of MS and its underlying causes, as well as treatment advances, have been made in the past few decades, but MS remains a complex and unpredictable reality for the 2.8 million+ people diagnosed around the world.

Ironically, the only real constant for people living with MS is change. There’s no set pattern or standard progression of the disease, so each person’s experience is unique. Some people with MS have mild symptoms that worsen slowly but sometimes improve, while others can have severe symptoms that drastically alter their daily lives.

All people with MS share some things in common, however, such as the need to stay informed on the ever-evolving research, find various lines of support and try to remain hopeful as they continue living with the disease.

To better understand what navigating life with MS really looks like, three women shared their MS stories with us. Their journeys demonstrate how MS can look different for different people and interestingly, how the language used to talk about the disease can greatly impact how people understand their realities.

Gina—Hamburg, Germany (diagnosed with relapsing multiple sclerosis in 2017)

When her youngest son was 4 months old, Gina started having problems with her eye. She’d soon learn she was experiencing optic neuritis—her first symptom of MS.

“Immediately after the diagnosis, I looked up facts on MS because I didn’t know anything about it,” Gina says. “And as soon as I knew what could really happen with this disease, I actually got scared.”

As her family’s primary income provider, she worried about how MS would impact her ability to work as a writer and editor. Her family was afraid she was going to end up in a wheelchair. However, for now, Gina’s MS is managed well enough that she still works full-time and is able to be active.

“When I tell somebody that I have MS, they often don't believe me the first time because I don't fulfill any stereotypes,” she says.

Overwhelmed by negative perspectives on living with MS, Gina sought support in the online MS community, which she found to be much more positive.

“I think it’s important to use as many positive words as you can when talking about MS.” It’s important to be realistic while also conveying hope, she says. “MS is an insidious disease that can cause many bad symptoms…that can be frightening, and you can't gloss over it, either.”

To give back to the online community that helped her so much, Gina started a blog to share her story and help others trying to learn about their diagnosis.

Though she deals with fatigue and cognitive dysfunction sometimes, Gina stays active swimming, biking, riding horses and playing with her sons, who are now 11 and 6.

Cognitive dysfunction is common in MS, with over half of people affected. It can impact memory, attention, planning, and word-finding. As with many aspects of MS, some people experience mild changes, while others face more challenges.

Gina says that while there’s still a lot of education about MS needed, she feels positive about the future of MS because there’s so much research being done.

Nathalie — Pennes Mirabeau, France (diagnosed with relapsing-remitting multiple sclerosis in 2002)

Nathalie was a teenager and a competitive athlete when she noticed her first symptoms of MS, but it would take four years of “limbo” before she was diagnosed.

“Ultimately, the diagnosis was more of a relief, than a shock,” she says. “Because when you have signs and you don’t know why, it’s worse than knowing, in the end, what you have.”

However, learning more about the disease—and the realities of disease progression—scared her.

“That glimpse of the future was direct and traumatic,” she says. Her neurologist explained that the disease evolves differently for everyone, and her situation might end up being serious or very mild. So, she decided to stop comparing herself to others with MS.

She said to herself, “We’ll see what happens, and you’ll manage it bit by bit.”

By 2005, Nathalie’s MS had progressed to the point of needing a wheelchair. However, that has not dampened her competitive spirit.

Nathalie began her international rowing career in 2009 and has won multiple world titles, including two Paralympic medals—silver in London and bronze in Tokyo. Now, at 42, she still trains 11 times a week. Fatigue can be a problem, and sometimes hard workouts leave her with muscle stiffness and shaking, but she credits her ongoing sports career for helping her feel in tune with her body’s signals.

“Over the years, I’ve learned to listen to my body, letting my body guide when I need to stop and take breaks,” she says.

Nathalie explains that she used to only look backwards because of the initial shock of her diagnosis. In time, she stopped thinking about what she couldn’t do anymore and focused on her future. She now lives in the following mindset: “Even when doors close, don’t miss out on those that open.” Instead of focusing on what she can’t do, she focuses on the opportunities she still has. Right now, this includes her training for the 2024 Paralympic Games in Paris, where she will compete for another rowing medal.

“I only go forward,” she says. “Well, I try, anyway…It’s easy to say, it’s not always easy to do. But that’s what I try to do.”

Helga—Johannesburg, South Africa (diagnosed with relapsing multiple sclerosis in 2010)

When Helga first started having balance issues and numbness in her feet, she chalked it up to her training as a runner. But when the numbness moved to her face, she knew something was wrong. She never guessed it was MS.

“When I was diagnosed, I felt completely overwhelmed and clueless,” Helga says. “I felt that I had nowhere near enough information. I did not know anything about the disease…I had no idea that it was going to be a process of continually monitoring and adjusting your lifestyle.”

In the beginning, Helga’s symptoms developed slowly, and she didn’t appear ill to others. She was even able to run for a few years after her diagnosis, but she couldn’t do marathons anymore, and she began to fall frequently due to balance issues and right-foot dragging. Then her cognition issues became more problematic, especially in her job as a trainer in a printing company.

“My executive function, decision-making and short-term memory were affected to the point that I was eventually medically unfit for work,” she says. She stopped working in 2017.

However, she didn’t stop living life. Even though she could no longer run, she continued to swim competitively. She got a Great Dane puppy and trained him as a service dog to help her walk. She also serves as vice chair of the patient support organization Multiple Sclerosis South Africa, and she advises others who have been diagnosed to join a patient advocacy group as soon as possible to get reliable information and meet others with MS.

Helga says she is “hopeful” about the future of MS. “I must say that I am so grateful that we have all the new medications available, because my life would not be the same if it wasn't for that,” she adds.

Part of how she manages her MS is by looking at the positives.

“If I could tell the world one thing about MS, it would be that MS is an incurable disease of the nervous system, but it's also the greatest teacher of valuing your health, family, friends, and managing change in your life,” she says. “My life is diversified in a way that I never, ever thought it would, and MS has been honestly the greatest teacher.”

Each MS journey is unique – with each person impacted experiencing different struggles, successes, and feelings as they manage this unpredictable disease. But the common thread is clear – there is a critical need for information, support, and hope. We are proud to participate in World MS Day and share these incredible stories of living life while living with MS.

Molly was found tied to a tree by the new owners of the house.

Molly, an adorable, affectionate 10-year-old pit bull, found herself tied to a tree after her owners had abandoned her.

According to The Dodo, Molly had “always been a loyal dog, but, unfortunately, her first family couldn’t reciprocate that same love back,” and so when the house was sold, neither Molly nor the family’s cat was chosen to move with them. While the cat was allowed to free roam outside, all Molly could do was sit and wait. Alone.

Luckily, the young couple that bought the house agreed to take the animals in as part of their closing agreement, and as soon as the papers were signed, they rushed over to check in.

Little girl shocks her mom by pulling out a pocket full of worms

Kids will absolutely test all parts of your personality. Not out of malicious intent, but simply because kids are innocent and don't don't understand unspoken social rules, especially when they're very little. One of those seemingly common sense unspoken social rules is that you don't go to the nail salon with worms in your pockets.

Scratch that, you don't walk around with worms in your pocket, period. That is unless you're on a fishing boat and you're in charge of bait and you run out of room in the canister filled with worms. I mean, there are a lot of things that would have to come into play to make having worms in your pocket socially acceptable. But kids don't know that, and one little girl, Kylee Grace, gave her mom a shock after they left the nail salon one day.

In the video posted to TikTok, which has now gone mega-viral with over 11.5 million views, Kylee and her mom are walking down the sidewalk after getting their nails done. Jenae, the little girl's mom, asks her daughter if she has a worm in her pocket. Then things quickly get hilariously weird.

Ring doorbell video captures what it's like to be the default parent.

Kids, man. I'm not sure of the scientific way audacity is distributed, but kids have a lot of it and somehow make it cute. That audacity overload is especially interesting when you're the default parent—you know, the parent kids go to for literally everything as if there's not another fully capable adult in the house. Chances are if your children haven't sought you out while you were taking a shower so you could open up a pack of fruit snacks, then you're not the default parental unit.

One parent captured exactly what it's like to be the default parent and shared it to TikTok, where the video has over 4 million views. Toniann Marchese went on a quick grocery run and *gasp* did not inform her children. Don't you fret, they're modern kids who know how to use modern means to get much-needed answers when mom is nowhere to be found. They went outside and rang the doorbell.

Back when we were children, this would've done nothing but make the dogs bark, but for Marchese's kids, who are 3 and 6 years old, it's as good as a phone call.

A Golden Retriever taking a break on the floor.

If you’re having trouble meeting a romantic partner, research shows you could improve your chances by getting a dog. A 2020 YouGov study found that 50% of Americans would be more willing to date someone if they had a dog, while only 9% would be less willing to do so.

Women are more interested in meeting someone with a dog (54%) compared to 46% of men.

People are more attracted to dog lovers for a pretty simple reason. They assume that those who have dogs are better at having long-term relationships. “People might infer that a dog-walking man knows how to form lasting attachments, has the resources to care for someone else (dog ownership is expensive!), and is reliable enough to do the daily work involved with dog ownership,” Theresa E. DiDonato Ph.D. writes in Psychology Today.

Mom calls out 'weaponized incompetence' by flipping the script on parental expectations

Hearing a woman say these things is ridiculous, and that's the whole point.

@clarabellecwb/TikTok

Too real. Tooooo Real.

While marriages are by far much more egalitarian than they have been in decades past, many women will tell you that when it comes to emotional and domestic labor, they still take on the lion’s share of responsibility.

Many women are using TikTok to call out this imbalance, even going so far as to share how it led to them filing for divorce. As for Clare Brown, she’s opting to illuminate the issue in a more satirical way.

Brown has amassed over 400,000 followers on her TikTok account, where a major part of her schtick includes what she calls “flipping the script” on social issues. And as of late, it’s her focus on parenting expectations that has people—particularly fed up moms—nodding in agreement.

In a series titled “flipping the script on weaponized incompetence,” Brown pokes fun at fathers who remain willfully ignorant by asking their partners for help on even the most basic tasks, thus escaping the responsibility of pulling their weight.
