Nutrition Across the Menstrual Cycle: How to Eat in a Way That Supports Hormones

Nutrition across the menstrual cycle involves adjusting food intake to support changing energy needs, hormones, and recovery throughout the month.

Hormonal fluctuations affect appetite, blood sugar regulation, nutrient needs, and how the body responds to calorie restriction. Eating the same way every day may not account for these changes — especially for women trying to conceive.

This doesn’t mean a complete overhaul every week. Small, intentional shifts are often enough.

Why nutrition across the menstrual cycle matters

Across the menstrual cycle, the body’s demand for energy and nutrients changes. Factors influenced by hormones include:

• insulin sensitivity

• metabolism

• inflammation

• stress hormone response

• micronutrient needs

• 
  

Ignoring these changes can contribute to fatigue, cravings, cycle disruption, or difficulty maintaining a healthy relationship with food.

Nutrition across the menstrual cycle focuses on support, not restriction.

Nutrition during the follicular phase

In the follicular phase, many women experience:

• improved insulin sensitivity

• stable appetite

• increased motivation

  
  

Helpful nutrition focus:

• balanced meals with protein, carbohydrates, and fats

• lighter meals if appetite naturally decreases

• adequate carbohydrate intake to support training and recovery

This phase often tolerates a gentle calorie deficit better if weight loss is a goal, though it still needs to be approached carefully when TTC.

Nutrition around ovulation

Ovulation can increase metabolic demand slightly and may affect hunger.

Nutrition considerations:

• don’t under-eat despite feeling energised

• prioritise regular meals

• include carbohydrates to support hormone signalling

Consistent fueling is more important than “clean eating” during this window.

Nutrition during the luteal phase

The luteal phase typically brings:

• increased appetite

• higher energy needs

• greater blood sugar sensitivity

This is not a lack of willpower — it’s physiology.

Helpful nutrition strategies:

• slightly increasing calories if needed

• prioritising complex carbohydrates

• including magnesium- and iron-rich foods

• eating regularly to avoid energy crashes

Trying to maintain an aggressive calorie deficit in the luteal phase often backfires.

Nutrition during your period

During menstruation, the body is recovering from the luteal phase and active bleeding.

Supportive nutrition can include:

• iron-rich foods

• adequate calories

• warm, easy-to-digest meals

• gentle hydration

  
  

This is often not the best time for restriction or dietary “resets”.

Nutrition across the menstrual cycle when trying to conceive

For women TTC, nutrition across the menstrual cycle supports:

• ovulation

• hormone production

• energy availability

• cycle regularity

Chronic under-eating — even unintentionally — can interfere with these processes.

A fertility-supportive approach focuses on adequate, consistent nourishment rather than extremes.

Key takeaway

Nutrition across the menstrual cycle isn’t about perfection or rigid rules. It’s about recognising that the body’s needs change — and responding with flexibility and support.

Small adjustments, applied consistently, are often more effective than aggressive plans.
