Why Am I So Hungry Before My Period?

Feeling hungrier before your period can be part of normal premenstrual appetite changes. Research suggests women eat more on average during the luteal phase, although this varies between people and cycles. There is no universal number of extra calories everyone needs.

You’ve eaten lunch. A perfectly respectable lunch.

And yet, an hour later, you’re wondering what’s available next.

If this sounds familiar in the days before your period, you may have noticed a real pattern. The useful question is how to respond to it without turning every snack into a negotiation.

Why does my appetite increase before my period?

Appetite changes and food cravings are recognised symptoms of premenstrual syndrome, or PMS. They can appear alongside changes in sleep, mood and energy, and may vary from month to month.

Fluctuations in ovarian hormones are thought to contribute to appetite changes, but the relationship is complex. Researchers are still working out how hormones, energy expenditure and eating behaviour interact across the cycle.

Your cycle also happens within your actual life. Before assigning all your hunger to hormones, consider whether you’ve skipped meals, increased your training or spent the day eating whatever was easiest between meetings.

Sometimes your period is approaching. Sometimes lunch was too small. Sometimes both.

What does the research say about eating more in the luteal phase?

The luteal phase is the time between ovulation and your next period.

A systematic review and meta-analysis published in Nutrition Reviews combined 15 datasets involving 330 participants. It found higher average energy intake during the luteal phase than during the follicular phase, with a crude average difference of approximately 168 calories per day.

That number describes what participants ate. It does not establish how many extra calories you personally need.

The review also included a relatively narrow population, with limits on age, average BMI and eating-disorder history. Its results cannot represent every woman.

Research is not entirely consistent, either. A small 2025 study involving 18 participants found no significant differences in appetite or energy intake between the phases it assessed.

The evidence supports leaving room for individual variation.

Do I need more calories before my period?

You may find you need more food to feel satisfied, but your cycle phase alone cannot determine your calorie needs.

Research on resting metabolism suggests it can be higher during the luteal phase, although findings vary and the size of the difference is uncertain. That does not justify a fixed extra-calorie prescription for everyone.

A practical starting point is to respond to hunger with an additional snack or a more substantial meal, then notice whether you feel comfortably satisfied.

You don’t need a spreadsheet’s permission to eat.

What can I eat when I’m hungrier before my period?

Start with meals you enjoy and can realistically prepare. A useful meal structure includes a source of protein, carbohydrates, some fat, and fruit or vegetables.

For example:

• Oats with yoghurt or fortified soy yoghurt, fruit and nuts.

• Rice with tofu or chicken, vegetables and olive oil.

• Bread with eggs or hummus, plus fruit.

• Potatoes with fish or beans and vegetables.

If meals are already substantial, adding a snack may be more practical than redesigning your whole day.

Try yoghurt with granola, toast with peanut butter, or crackers with hummus. These are flexible options, rather than special foods you must eat in a particular phase.

What if I’m craving chocolate or something sweet?

A craving is a desire for a particular food. Hunger and cravings can overlap; you don’t have to perfectly classify the feeling before responding.

You can include the food you want. If you’re also hungry, consider having it alongside something more substantial.

Chocolate after lunch. A pastry with yoghurt. Toast followed by the biscuit you were thinking about anyway.

The goal is to find an approach that feels satisfying and manageable.

How can I spot my own pattern?

For a few cycles, briefly note:

• When appetite changes appear.

• Whether meals have been regular and satisfying.

• Training, sleep and stress.

• Any other premenstrual symptoms.

You’re looking for information that helps you prepare. Perhaps keeping an afternoon snack available makes those days easier. Perhaps the strongest pattern is missing lunch on your busiest days.

Tracking symptoms across at least two cycles can also help when discussing possible PMS with a healthcare professional.

When should I ask for support?

Speak with a healthcare professional if symptoms affect your daily life or don’t improve with practical changes. You don’t have to dismiss something as “just PMS” because it returns every month.

If eating regularly feels distressing, involves loss of control or leads to compensating through restriction or exercise, seek support from a qualified professional rather than relying on cycle advice alone.
