There are many reasons why a person's period may come early, and one of the most common causes is a change in diet. Research has shown that a change in diet can lead to a change in hormone production, which can then affect the menstrual cycle. This is especially true for diets that involve drastic changes in daily portion sizes or types of food consumed, such as the keto diet, which can cause a decrease in estrogen, leading to irregular cycles. Intermittent fasting can also cause abnormal cycles, including extremely heavy or light bleeding. In addition, restrictive eating and excessive calorie restriction can lead to inadequate calorie intake, disrupting the hormones that regulate the menstrual cycle.

What You'll Learn
Calorie restriction and menstrual changes
Major weight changes, whether weight loss or gain, can disrupt hormone levels and cause early, irregular, or missed periods. For instance, the keto diet, which often results in rapid weight loss, can decrease estrogen levels, leading to irregular cycles and even period spotting. Similarly, the paleo diet, which involves drastic changes in weight and estrogen production, can also affect the menstrual cycle. Intermittent fasting can cause abnormal cycles with extremely heavy or light bleeding and even skipped periods as the body tries to regulate hormones.
Being underweight or overweight can impact the menstrual cycle. If the body fat percentage is too low, the body may stop producing estrogen, leading to amenorrhea. On the other hand, obesity during adolescence can also lead to irregular periods.
It is important to note that while some diets may be associated with menstrual changes, a vegetarian diet, for example, may not directly impact the regularity of the menstrual cycle. However, vegetarians may experience a higher rate of premenstrual and menstrual symptoms, irregular cycles, and heavier periods due to potential nutritional deficiencies. Therefore, it is crucial to ensure adequate nutrition and consult a healthcare professional before starting any new diet.

Weight loss and early periods
Weight and diet are closely linked to menstruation. Significant weight changes, whether weight loss or gain, can affect the regularity of the menstrual cycle. Extreme dieting, gastric bypass surgery, or eating disorders can cause irregular periods or cause them to stop altogether. This is because when the body does not get adequate energy, it may not produce the reproductive hormones required for ovulation.
A calorie deficit may disrupt the hormones that regulate the menstrual cycle. Restrictive eating, such as in the case of anorexia nervosa, can lead to inadequate calorie intake compared to energy burned, affecting hormone production. This can cause shorter cycles or amenorrhea, the absence of periods.
Some specific diets have been linked to changes in the menstrual cycle. The keto diet, for example, can cause a decrease in estrogen, leading to irregular cycles and period spotting. The paleo diet, which involves drastic weight changes and estrogen production, can also affect the menstrual cycle. Intermittent fasting can cause abnormal cycles with extremely heavy or light bleeding, and the body may skip periods as it tries to regulate hormones.
Vegetarian and vegan diets may also impact the menstrual cycle. A study suggested that vegetarians experience more premenstrual and menstrual symptoms, irregular cycles, and heavier periods than non-vegetarians. Vegans and vegetarians may also be at risk of anemia due to iron deficiency, which can be a concern for those with heavy periods. However, this can be mitigated by supplementing with iron-rich foods such as spinach and legumes.
On the other hand, some diets may help reduce troublesome PMS symptoms. Diets rich in omega-3 fatty acids, calcium, and vitamin D, and low in animal fats, salt, and caffeine may alleviate PMS. High caffeine intake, for example, has been linked to irritability, poor sleep, and menstrual cramps.
Overall, while diet can impact the menstrual cycle, the relationship is complex and influenced by various factors, including weight changes, nutrient intake, and hormone regulation. It is always advisable to consult a healthcare professional before starting a new diet or if you notice significant changes in your menstrual cycle.

Hormone changes and early menstruation
A regular menstrual cycle is a sign of good health. The menstrual cycle is regulated by hormones such as estrogen and progesterone. Therefore, changes in these hormones will affect the menstrual cycle. Research shows that our hormone production can be affected by our diet, so a change in diet can affect the menstrual cycle. For instance, a calorie deficit may disrupt the hormones that regulate the menstrual cycle and can cause shorter cycles or amenorrhea (the absence of periods). Restrictive eating, such as in the case of anorexia nervosa, rapid weight loss, or famine, often means that calorie intake is inadequate compared to energy burned. This can disrupt the hormones that regulate the menstrual cycle.
Major weight changes can also cause irregular periods or cause them to stop altogether. Extreme dieting, gastric bypass surgery, or eating disorders can disrupt hormone levels, causing irregular periods. Being underweight can cause irregular menstrual cycles or, in severe cases, amenorrhea. If the percentage of body fat is too low, the body will stop producing estrogen and menstruation will stop. Fad diets that drastically change daily portion sizes or food types can change how often you get your period or how heavy it is.
The keto diet, for example, can cause a decrease in estrogen, making the cycle more irregular and even causing period spotting. Similarly, the paleo diet can also cause drastic changes in weight and estrogen production. A vegetarian diet can be healthy if nutritional requirements are met. However, vegetarians have been found to have a higher rate of self-reported premenstrual and menstrual symptoms, as well as irregular cycles and heavier periods.
Intermittent fasting can also cause abnormal cycles, with either extremely heavy or light bleeding. Some women may experience numerous skipped periods as their bodies try to regulate their hormones.

Nutritional deficiencies and irregular periods
Nutritional deficiencies can cause irregular periods. A diet that is too restrictive or does not meet one's energy needs can affect the hormones that regulate the menstrual cycle. For example, excessive calorie restriction can lead to a deficit in the hormones that regulate menstruation, causing shorter cycles or amenorrhea (the absence of periods). This is often the case with restrictive eating disorders, rapid weight loss, or famine. Being underweight can also cause irregular menstrual cycles or amenorrhea due to a lack of body fat, which is necessary for estrogen production. Regaining weight safely under the guidance of a health professional and incorporating healthy fats from sources like fish, nuts, oils, and avocados can help restore estrogen levels and resume menstruation.
Additionally, specific nutrient deficiencies have been linked to irregular periods. For instance, studies have found a relationship between vitamin D deficiency and menstrual cycle disorders, with women who have low vitamin D levels having almost five times the odds of experiencing menstrual irregularities. Vitamin D supplementation has been suggested as a possible treatment for regulating menstrual disorders in these cases.
Thyroid conditions, which can be caused by a nutritional deficiency, are also associated with irregular periods. Thyroid hormones are considered "master hormones," and a thyroid condition should be considered when investigating the causes of irregular menstruation. Furthermore, iron deficiency has been linked to premenstrual and menstrual symptoms, with vegetarians reporting a higher rate of these issues compared to non-vegetarians. Ensuring adequate iron intake is crucial for vegetarians to avoid anemia, especially if they experience heavy bleeding during their cycles.
While the impact of isoflavones on menstrual cycle regularity remains controversial, some suggest that altering one's intake of isoflavones could be considered if other approaches have been exhausted. Overall, nutritional deficiencies can disrupt hormonal balance and contribute to irregular periods, and addressing these deficiencies through dietary changes or supplementation may help restore menstrual regularity.

Vegetarian and vegan diets and menstruation
A person's diet can impact their menstrual cycle length when food groups are restricted, leading to a lower overall intake of calories. Extreme caloric restriction can affect cycle length or stop menstruation altogether. A well-planned vegetarian or vegan diet can be appropriate at any life stage as long as all nutrient needs are met.
Vegetarian and vegan diets have been associated with a reduction in preterm births, an improvement in ovulatory infertility, and lower risks of gestational diabetes mellitus. They can also help with period cramps and endometriosis. However, studies suggest that people who follow plant-based diets could be more at risk of iron deficiency or low iron stores, which can cause anaemia.
A study by Baines and colleagues suggested that vegetarians have a higher rate of self-reported premenstrual and menstrual symptoms, as well as irregular cycles and heavier periods, compared to non-vegetarians. This may be due to a lower intake of iron and other nutrients. Therefore, it is important for those on a vegetarian or vegan diet to ensure they are meeting their nutritional requirements, especially their iron requirements.
In summary, a vegetarian or vegan diet can affect menstruation, but this is usually due to a lack of proper nutrition rather than the inherent nature of the diet. It is important to consult a doctor or nutritionist to ensure that meals are wholesome and meet nutrient and calorie needs.
