Yes, you can gain weight around your period from eating too much, but it's usually temporary and often linked to hormonal changes causing bloating, water retention, and intense cravings for salty/sweet foods, making it easy to overeat; however, the main weight gain is often water, not fat, resolving as your cycle progresses. Overeating contributes to actual calorie surplus weight gain, while water/GI issues add to the scale's number, creating a feeling of significant weight gain (1-5 lbs is common) that disappears a few days after your period starts.
This is a normal part of premenstrual syndrome (PMS). However, when overeating becomes difficult to manage, it may be an indication of a more serious condition, such as a binge eating disorder or premenstrual dysphoric disorder.
Changes in these hormones during the luteal phase can increase appetite and cravings, often for high-calorie or comforting foods (3). This isn't a random urge—your body may actually need the extra energy as it prepares for menstruation (7).
Gaining weight on your period is normal and usually falls within a range of two to six pounds depending on the individual. Hormonal changes are often the root cause of menstrual weight gain. They cause your body to retain water and then lose it after your period ends.
If you want to lose weight, it's important to know that your metabolism speeds up during the luteal phase. This means you burn calories faster than usual in the week before your period.
One such example is bloating. This is a very common PMS symptom in the days leading up to and during our period [5], and while bloating isn't the same as weight gain, it can both cause discomfort and make our belly swollen, so our clothes fit a little tighter — giving the perception of weight gain.
You typically don't burn more calories during your period, but your metabolism might slightly increase during the luteal phase of your cycle. Cravings and increased hunger are common due to hormonal changes, emotional factors, and societal influences.
For many women, weight starts to climb in the second half of their cycle after ovulation and culminates with a peak on the first day of their period. Several studies have found that peak fluid retention is on the first day of menstrual flow and then it begins to drop off again.
During menstruation, you should avoid heavy/intense exercise, excessive caffeine, alcohol, salty/sugary foods, and tight clothing, as these can worsen cramps, bloating, and mood swings; also, practice good hygiene by changing menstrual products frequently (every 3-4 hours for tampons) to prevent infection and avoid strenuous activities if you feel fatigued or in pain.
Yes, it is true you weigh more on your period or more accurately, right before and during the first few days. The weight increase is real and measurable, but what's causing matters: Water retention: Hormonal changes (particularly rising progesterone) cause your body to hold onto 1-5 extra pounds of water.
Missed or late periods
If you experience menstruation, you may want to avoid weighing yourself in the days leading up to your period. That is because your hormones can cause weight fluctuations that would affect the number on the scale.
Understanding why you gain weight during PMS
The hormone changes that occur around your period cause excess gas in your gastrointestinal tract. This can give you the feeling of weight gain and cause your clothes to feel uncomfortable and tighter than usual.
After menstruation, the body often sheds excess fluid, leading to a slight weight decrease. This is not fat loss but a reduction in water weight.
Most women are hungriest in the middle of the progesterone phase of the menstrual cycle, the so called, mid-luteal phase. There were higher fasting insulin levels at this mid-luteal stage of the cycle which is another factor that affects our drive to eat.
Five foods to eat during menstruation
Popular Period Cravings
You may feel hungrier on your period due to changes in levels of certain hormones, like estrogen and progesterone. Hormonal changes can cause cravings for certain foods like carbs and sweets. This may be your body's way of preparing to support a potential pregnancy.
Weight loss during periods can occur due to hormonal fluctuations that affect metabolism, appetite, and water retention. Changes in estrogen and progesterone levels can lead to increased metabolism, reduced appetite, and the elimination of excess water weight, contributing to temporary weight loss.
A good night's rest goes a long way during your period. Some women experience the Premenstrual Syndrome (PMS) phase, making the start of their period a little more foggy, moody, and mentally draining.
Many people experience a temporary weight gain of 0.5 kg to 2.2 kg during menstruation. Some people may gain up to 5kg (10 pounds). It may start 5 days before your period and return to normal by the end of your period.
"Endo belly" is the nickname people use for the dramatic swelling that often comes with endometriosis. Your abdomen (belly) may stretch from under your ribs down to your pelvis, leaving your whole midsection tight and painful. Some people say it makes them look six months pregnant.
Stay hydrated: Drinking water is always important, especially during your period. Staying hydrated can help reduce headaches and help ease water retention and bloating.
