Why Do You Get Hungry Before Your Period?


Cravings, bloating and then the hunger – the best diets are often laid asunder by your period. For many women, the symptoms leading up to and during the week of your period are outrageous, and one of these is the hunger that seems to ratchet up from nowhere.

The reason for this increase in hunger is simple. Your body uses more calories during the time right before and in some cases during your period. This increase in calories makes your body burn more calories during this time, and as the calories as burning you’re going to feel hungry more often.

To compound this, the hormones at work in your body during this time are also likely making you crave particular food items. So suddenly, you’re starving, you already feel bloated from water weight and now you want to eat chocolate or chips. No wonder we all feel so miserable during this week!

Why Do I Get So Hungry Before and During My Period

Calories are units of energy. You can think of them like tiny gallons or liters of gas. Just like a car burns through gas, your body burns through calories. Every day, if you were to lie in bed and do nothing at all, you would burn a certain number of calories just being alive. This number is your Basal Metabolic Rate, or BMR.

As you lay in your bed doing nothing at all, your body is burning up fuel, or calories, keeping your digestive system working, helping your heart beat and all of the other wonderful things that happen inside us that we don’t have to think about on a daily basis. Every thirty days or so, the systems in your body pick up another task.

With the menstrual cycle, the week of your period makes your body do some extra work. This extra work burns more calories and your BMR actually goes up. In some women, the week of your period can make you burn up to fifteen percent more calories, and you haven’t changed a single thing about your lifestyle!

Eating and Your Period

Of course, if you’re trying to figure out why your period makes you so hungry, the answer is clear. Your body is doing more work; your body needs more calories. To get the calories it needs, your body sends a message to your brain telling you you’re hungry more often. Since you’re feeling hungry, you eat.

This is a tricky week for women who are paying close attention to their figures, however. Being extra hungry often means you are compelled to eat. The additional symptoms of this week make eating even more enjoyable. I mean, really – if you’re sitting in sweat pants already watching weepy movies, wouldn’t it taste better with a pint of ice cream?

The trouble is, you may feel hungrier, but the extra calorie burning can be a bit deceptive. Your body is burning some extra calories, but only about 100 to 300 per day, and only for a few days at a time. Sadly, 100 calories is the same as one of those tiny snack packs you can put in your lunch while you’re dieting. At most, you can enjoy a candy bar for close to 300. A pint of ice cream is easily 500 to almost 1,000 calories at a time – it’s not justified by period calorie burn.

Controlling Hunger and Your Period

The best way to stay healthy and watch your figure is to listen to your body more than your appetite. You may feel a strong craving for ice cream, but that probably has more to do with comfort then nutrition. If you’re feeling like shoveling through a bag of chips, don’t give in to the craving. If you really can’t stand it, count out enough chips to be about one serving and then stop. Savor the chips you’re eating, but leave the rest put away.

If you can prevent your appetite from getting the best of you by eating filling foods without many extra calories such as lean protein and vegetables, you will benefit in another way from feeling so hungry this week. When your BMR goes up, as it does the days before your period, you’re burning some extra calories. If you fend off the desire to shove junk in your face this week, you can actually burn off more calories instead of consuming them.

If you are one of the lucky ones burning an extra 300 calories per day for about five days, you’ll lose half a pound by not doing anything except waking up in the morning. After gaining up to five pounds in retained water, losing that water plus a bit more feels outstanding the week after your cycle – it just takes a bit of willpower to reach that point.

    wow didnt know that metabolism rose before ur period. good to know that i can eat more and not feel guilty. i always know when i'm going to start my period soon because i can eat and eat and not get full. i usually only eat one big meal a day with lots of snacking. today, however, i've had 3 full meals and am still hungry. 

  • Cheryl March 2, 2011, 1:34 am

    I was looking for tips from women on how to get past these intense cravings to eat right before our period.  For years I start a diet and do very well till I hit this time frame, and bam…crash and burn.  Its just so frustrating. Any advise??  Thanks!

  • allyson June 25, 2011, 3:25 pm

    Thanks so much for this information. Like others have posted, I feel so guilty yet uncontrollable at this time. It's comforting to know there is a physiological reason. This should help me mentally and emotionally handle myself better for next month. Have a great day everyone:)

  • Lizzie January 10, 2012, 2:26 am

    I am glad I'm not alone thinking that it's just me who is eating way too much before my period. It's insane! I too do well on my diet/ calorie intake until my period…I just eat even though I'm not hungry! I am making note in my yearly planner to pinpoint the days and times to keep an eye on it and keep the hungry monster at bay

  • NomNom January 17, 2012, 3:58 am

    I'm a RAVENOUS animal. I literally sat next to the pantry and just ate and ate. I feel so guilty because I've been watching my calories and I feel like I'm a drug addict or something, there is no stopping me! So far I've consumed about 20,000 calories worth of crap, and I know in 10 min I'm going Walter Hudson on my pantry again. I'm going to try to drink a gallon of water to slow myself now.

  • shaneira January 20, 2012, 2:02 am

    i dont have an eating disorder or anything, but i normally eat about 400 calories a day, but when im on my period, i eat like 1000 calories. then i feel so guilty and scared because i cant workout because of the pain. I HATE PERIODS!!!

  • jc January 28, 2012, 12:06 am

    Those who say its "all in your mind" can stuff it!  It is like clockwork for me. 3-5 days before and I feel like there is an animal in my stomach growling to be fed.  Hunger actually WOKE ME UP this morning at 6am! And this is after I had a full meal last night.  Then, tunger at 10 am caused my stomach to churn and make such ungodly noises while in my cube I know my whole department must have heard.  My stomach is gowling and churning right now in fact.  And I KNOW its due to my period as does all other women know it.  You know your own body.  So any nay-sayers can just scoot.  The problem of course is that I have been really on a diet and its been ok. But today I am absoultely tortured. And there are two boxes of Girl Scout Cookies in the cupboard. LORD GIVE ME STRENGTH!

    I knew it had to be a reason… If anyone needs help with it, I try to fight the hunger drinking green tea with milk, it makes you feel full for a while, also green tea is really good for your health and helps to absorb less fat… and during the winter a hot beverage feels great!

  • Armani March 4, 2012, 6:52 pm

    I feel so upset. I managed to behave for about 3 weeks, and now I've ruined all the hard work. I've eaten so much & feel so guilty now.
    Can anyone please advise me on how I can stay away from over-eating during this time of the month?

  • KvE March 9, 2012, 11:22 am

    I ALWAYS know when it's coming because I get so hungry and crave five things (that I want to eat at the same time). Sour patch kids, jelly beans, chocolate, pretzels, and potato chips. 
    Trying to ignore my cravings doesn't work for me. Sandwich bags are my savior at this time. Once I get my junk food I portion it into sandwich bags. I use the serving size to figure out what of each item I can put into individual bag with a limit of 250 calories per sandwich bag. I put the sandwich bags in the furthest highest cabinet. It is less tempting that way because I already don't feel like getting out of bed. 
    For meals I try and stick with soups and use a smaller than normal spoon so it lasts longer. Also I will sometimes put some rice into my soup. Making a big pot of soup, especially in a slow cooker, is cheap, low on calories, and can make many meals. 
    For exercise I don't feel like doing it at all. Curled up in bed with some movies and a bag of popcorn is where you will find me. Since my movie time is watching netflix on the wii in between each movie I will force myself out of bed for 10-15 of WII sports or WII fit. I even set a timer so I don't cheat. 
    I try and plan for this in advance, preparing my snacks and soup a day or two before. It's too easy to not feel like doing it otherwise.

    This is a tad after the other comments, but after finding this and reading it all, it makes me feel sooooo much better. Sucks that our bodies only burn and extra 100-300 cals, but during this week leading up to my period … IDC! I feel like a savage because I can eat and eat and eat and never feel full. It's absolutely ridic. Then the bloating from the period on top of the crap I've eaten … I feel like a whale. And I get embarrassed because my husband will look at me crooked as I'm taking a bite of his food after I've eaten all of mine hahahhaa. I feel like I'm preg all over again! I have no will power or self control. I give into my cravings, and I try to do so within reason. Otherwise, I'm soooo mean because I'm starving. Ugh it's a lose-lose situation ladies!

    i deal with extreme hunger two weeks before my cyle. here is what i do. i make a huge bowl of oatmeal and fill top is off with apples, blueberries,   and sometimes a small amount of almonds.  that ususally holds my for  at least five hours. i also only eat ezekial bread when i crave bread. it has less calories but i only eat the cinnamon raisen one.  also at dinner i make a huge vegetable omlet. i load up my omlet with spinach, fresh tomatoes, onions, green and red peppers and cayanne pepper. i also add one slice of low fat cheese. swiss or parmesion has less fat compared to the other ones. i also make a huge vegetable lasagna that i eat off of for several days. i only use whole grain noodles, i precook a bag of mixed beans like red and black beans. i precook brussel spouts , spinach, broccoli, and carrots, then i slice them up. i saute onions green peppers and garlic and mix with tomatoe sauce. i then layer my lasagna with a layer of sauce at the bottom vegetables all mixed together, beans and alow fat cheese. i make to layes and top with cheese, then i bake for about tenty min. on three hundred degrees. it might now sound apetizing but its good. low fat and keeps me full.

    Start by not keeping junk food in your house. You'll have no other choice but to eat healthily. 

  • Tayla June 7, 2012, 12:35 am

  • Lozie July 26, 2012, 11:12 pm

    I was so relieved when I red the part about gaining a few pounds just before your period. I was starting to get worried as I normally put on about 7 pounds and my boobs go from a c cup to d. Unfortunately they go down the day I start but And luckily the weight drops right of but I can't stop eating!! I could feed me a and my partner for a week on what I consume in days!!

  • Ann July 7, 2013, 5:48 am

    I have that every time before my periods. I am skinny though. But before my periods I always get more hungry and eat more.

  • Kaolru July 21, 2013, 9:14 pm

    Well this explains a lot. The calories I add to my diet during the week before my period do not compare to the ones I lose when I actually get my period. Due to sickness and pain, I can't eat at all. At max I've lost ten pounds in two days. It's terrible.
