You typically weigh more (a few pounds) on your period due to hormonal shifts causing water retention, bloating, and slower digestion, but this is temporary water weight, not fat, and usually resolves within a few days of bleeding starting. The weight gain comes from fluid buildup (extracellular water) and sometimes constipation, not necessarily increased fat.
The menstrual cycle itself doesn't seem to affect weight gain or loss. But having a period may affect your weight in other ways. Many women get premenstrual syndrome (PMS). PMS can cause you to crave and eat more sweet or salty foods than normal.
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.
The weight usually appears in the days before your period and goes away about 3-5 days after you start bleeding. And remember, just like many other symptoms of being on your period, like food cravings and low mood, not everyone gains weight in the lead-up.
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.
The simple answer is: hormones. Changes in your hormone levels cause all sorts of changes in your body, one of which is your metabolism, which is linked to weight loss.
The short answer: Yes, weight loss due to a restrictive diet, over-exercise — or a combination of the two — can absolutely cause you to lose your period. The longer answer: Weight loss is contextual, and it's important to keep in mind why somebody is losing weight before assuming it's the reason their period stopped.
Make time for physical activity
Set a goal of at least 150 minutes of aerobic activity per week. Aerobic exercises increase your breathing and heart rate, such as a brisk walk, bike ride or swimming. Not only can aerobic exercises help with weight loss, but they can also help keep your heart and lungs healthy.
Causes of weight gain before and after the menstrual cycle
Due to changes in progesterone and estrogen hormones at this time, the body has many fluctuations. Up to 90% of women experience this weight gain because hormonal changes in the body cause the tissues to retain more water, causing water heaviness.
So, in the end, while we may feel hungry just before, or during, our periods for several societal, physiological, and psychological reasons, we do not need to consume more Calories.
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.
The 3-3-3 rule for weight loss is a simple, habit-based method focusing on three key areas: 3 balanced meals a day, 3 bottles (or ~1.5L) of water by 3 PM, and 3 hours of physical activity per week, aiming for consistency over complex diets. It simplifies fat loss by establishing rhythm through consistent eating, adequate hydration to support metabolism, and regular movement, promoting sustainable health without intense calorie counting or restrictive rules, says Five Diamond Fitness and Wellness, Joon Medical Wellness & Aesthetics, and EatingWell.
She lost 16 pounds in 3 weeks to fit into her vintage Met Gala gown. How did Kardashian lose weight? She says she cut carbs and ate “just the cleanest veggies and protein.” She also ran on a treadmill and wore a sauna suit twice a day. Kardashian's 3-week weight loss sparked concern over the impact on mental health.
Losing 5 pounds a week comes to reducing your food intake by 3500 calories over seven days. The value that represents the decrease in calorie intake is known as the calorie deficit. If you want to lose 5 pounds in a week, you will need to reduce your food intake by 17,500 calories, which is a huge calorie deficit.
Females tend to gain the most weight during two key periods: emerging adulthood (late teens to mid-20s) when life changes often disrupt habits, and midlife (around ages 45-55) during menopause due to hormonal shifts that decrease muscle and increase abdominal fat, although the rate of gain slows in later decades. While the 20s see significant overall gain, menopause brings distinct body composition changes and fat redistribution, not just scale weight.
A stress period looks like menstrual changes due to hormonal disruption, featuring spotting, early/late/missed periods, heavier/lighter flow, longer duration, bigger clots, more cramping, worse PMS, and potential loss of libido, alongside physical signs like headaches, fatigue, muscle tension (neck/back pain), jaw clenching, and digestive issues, all stemming from elevated cortisol and disrupted reproductive hormones.
The general (social media) consensus is that people are at their 'most attractive' during the first half of the cycle, the follicular phase, which begins on the first day of the period and ends after ovulation, and at our aesthetic low point during the latter half, the luteal phase, which starts after ovulation and ...
You might find yourself soaking through a pad or tampon every hour. While the color is often dark red, look out for grayish tissue. A foul odor with clots can also signal an infection. Regularly passing large clots suggests an underlying issue.
As per a report by the Journal of Sleep Research, menstruating women who sleep for less than 6 hours per night are more likely to be affected by irregular periods and experience uncomfortably heavier flows.
The rise in progesterone during the luteal phase can cause the body to retain more water, leading to bloating or a feeling of heaviness (11). Research shows that this “weight gain” is usually due to fluid retention, not fat gain, and typically goes away after you start your period (4).
Here are additional suggestions to decrease bloating:
Drink plenty of water. It may sound contradictory, but a well-hydrated body is less likely to retain fluid. Cut back on dehydrating drinks such as tea, coffee and alcohol. Cranberry juice has a mild diuretic action.
People naturally lose muscle after 40, especially women after menopause. Because muscle burns more calories than fat, this can slow down your metabolism and make it harder to shake those stubborn pounds.
