The hormone progesterone, which rises prior to the onset of menstruation, can also stimulate appetite. The body burns more calories during your period. Pre-menstrual food cravings can be more severe for those with PMS or depression. Most weight change during your period is due to water retention, not fat gain.
There is good evidence that progestogens, such as progesterone, can stimulate appetite. Levels of this sex hormone reach their peak about one week before menstruation begins, which can help explain pre-period munchies. In a similar vein, while BMR decreases during menstruation, it rises to its maximum just prior to it.
In fact, it's completely normal and OK to eat more during your period. We explain why, below! Your menstrual cycle increases your metabolic rate, which is the amount of energy you expend while at rest. The weeks leading up to your period, you actually burn more calories than any other time of the month.
Hormone levels fluctuate throughout the 28-day menstrual cycle. These changes can affect a person's appetite and may also lead to fluid retention. Both factors can lead to perceived or actual weight gain around the time of a period.
“It's very minimal though,” she says. “Approximately 100 calories per day.” And no, getting your period is not like a natural form of “blood doping.” “It's not about having more blood in your system,” Sims says.
The menstrual cycle does not directly impact weight loss or gain, but there may be some secondary connections. On the list of premenstrual syndrome (PMS) symptoms are changes in appetite and food cravings, and that can affect weight.
Many women typically see around two to six pounds of weight gain around their period, but every body is different.
Basal metabolic rate varied significantly with the menstrual cycle. Basal metabolic rate decreased at menstruation and fell to its lowest point approximately 1 wk before ovulation subsequently rising until the beginning of the next menstrual period.
On the plus side, when you're actively bleeding, your body is sloughing off the uterine lining and preparing for a fresh cycle. As the days go on, hunger and cravings dissipate, you lose the bloat (and any excess pounds). In fact, you're at the lowest weight of the month right after you stop bleeding.
How long does period weight gain last? Don't worry—assuming the weight gain is just temporary water retention, your weight should return to normal soon. “Water weight usually goes away about three to five days after your period starts,” says Dr. Landry.
It's normal to gain three to five pounds before your period, and this weight gain usually goes away a few days after your period starts. Understand your symptoms and get to know what's linked to PMS and your cycle in the PMS chatbot.
Your skin during menstruation
During the first days of your cycle, levels of hormones such as estrogen and progesterone are low. This causes dry, dull skin and can make lines or wrinkles appear more obvious. Moisturizing and hydration can be great skin boosters during the initial days of your cycle.
It is true that water retention leads to weight gain during periods but that is very minimal and not the same for all. Some women gain more than others. You can expect to gain 500 grams to 1.5 kilos of weight when you are bleeding.
Heavy menstrual bleeding often causes women to feel tired, commonly known as period fatigue. This is normal due to the decrease in oestrogen levels, which occurs around this point in your menstrual cycle. Your energy levels will usually return to normal within a few days as your hormone levels begin to increase again.
Use your scale every morning after you empty your bladder (and before you eat or drink anything), wearing as little clothing as possible. Because you lose water weight overnight, you'll get a lower number, too. Place your scale on a hard, even surface—no carpeting.
But if you did need a little extra assurance it turns out women do actually need more calories when they're menstruating. Research has found that women need between 100 and 300 extra calories a day during the week leading up to their period.
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.
Period weight gain does not mean that you have gained the lost fat again. It is just water retention that happens due to change in the level of hormones and excessive intake of salty and unhealthy food items. Water weight gain is temporary and you lose it within a week after your monthly menstrual cycle ends.
It is possible that the behavior of binge eating itself may affect menstrual function independent of weight because binge eating may interfere with hormonal function that, in turn, affects menstrual function.
For one, you don't burn more calories on your period, contrary to some locker room chatter. If anything, Sims says you burn slightly more calories when your hormones are higher (known as the post-ovulation luteal phase) because your heart rate, respiratory rate, and core temperature increase.
It turns out our bodies require 100 – 300 more calories during our luteal phase (the week before our period is due). This is because our Basal Metabolic Rate (BMR – the number of daily calories needed to stay alive) during this time increases by 10-20%.
