# How do body clock, exercise, and appetite relate to PMS?

As PMS increased, physical activity decreased, appetite increased, and women preferred emotionally comforting foods and evening hours.

 Early or limited evidence

931 women aged 18-40 at a private nutrition clinic in Istanbul

## What they did

Cross-sectional survey of 931 women aged 18-40 at a nutrition clinic in Istanbul answering questions about body clock, physical activity, PMS, appetite, and food preferences.

## What they found

All associations were highly statistically significant (p<0.001). As PMS increased: physical activity decreased, appetite increased, food preferences shifted toward emotionally attractive foods, and evening chronotype preference increased.

## What it means for you

PMS is linked to reduced activity, increased appetite, and comfort food cravings. However, this observational study cannot show whether PMS causes these changes or vice versa. Results are from a clinic population in Istanbul.
