Part of the “Small changes, big results” series.

The habit in one line

Walk for 10 minutes after dinner, every day for 30 days.

Finish dinner, wait a few minutes, then walk at an easy pace. Indoors, on the terrace or around your building all count.

Why it's worth doing for your hormones and cycle

After a meal, your blood sugar rises. Studies suggest that moving a little afterwards may help keep that rise lower than sitting. A review of studies found that light walking after eating helped more than sitting, and more than standing.

In people with type 2 diabetes, a small trial found that walking soon after meals lowered blood sugar after the meal more than walking at another time of day. We don't have the same studies in PCOS, but steadier blood sugar is something your hormones like.

Evenings are also the longest stretch of sitting for many of us. A short walk breaks it.

What it can do for weight loss over time

• It adds up. Ten minutes a day is 70 minutes a week, close to half of the WHO's 150 minutes a week for adults
• By day 30, you will have walked about 5 hours in tiny pieces, without changing your schedule
• It builds the habit of moving every day, which matters more than any single workout

What to expect, and when

• Week 1: The hardest part is getting up. Keep it easy
• Weeks 2-3: It becomes part of dinner, like brushing your teeth
• Day 30: A steady evening routine, and a base you can build on with a longer walk

Imagine Ritu, 34, who works late and usually collapses on the sofa after dinner. She leaves her sneakers by the door and walks around her building for 10 minutes. By week three, her husband has started joining her.

That is how small changes become big results.

What it works best with

• A walk after lunch too, if you can
• Strength training or other exercise on some days
• Good sleep
• Your treatment and follow-ups, if you have any

Think of it as the first domino. It is not a cure for PCOS. And 70 minutes a week is a starting point, not the finish line.

A quick check before you start

• Walk at an easy pace. You should be able to talk
• Wait a few minutes after eating, so you don't feel heavy
• If you feel dizzy or unwell, or you have a medical condition, check with your doctor before walking after meals

When to talk to a doctor

• Very irregular periods, or no period for 3 months or more
• Heavy or painful periods
• Sudden weight gain or loss
• Worsening acne, hair fall or facial hair
• Extreme hunger, thirst or tiredness
• Trouble conceiving after a year of trying (6 months if you are over 35)
