(01) Who it's for

Written for the woman who's been told "it's normal" once too often.

  • Your results are "within range", but you don't feel within range.
  • You're slim, and the family history still worries you.
  • You want to know which tests to ask your GP about, and the words to use.
  • You want food advice that includes the food you actually eat.

It isn't

A replacement for your doctor, a diagnosis, or a quick fix. It's the context and questions that make your next appointment count.

(02) What's inside

Four parts. One clear system.

01

The framework

A chapter-by-chapter path from what's shared across South Asian women, and what isn't, through to the habits that matter most.

02

Sample eating days

Real days of eating that show how to reach your protein and fibre targets, starting at breakfast, with familiar food.

03

The 14-test blood panel

The markers to discuss with your GP, how to read a result beyond "normal / not normal", and when to retest.

04

The advanced section

For when you want to go deeper, including life stages and the questions that don't fit a ten-minute appointment.

(03) The author

Shweta

A decade in health tech as a marketing executive, reading clinical research for a living. A South Asian mother who wanted better answers than "it runs in the family".

Every chapter starts from the research and says plainly where the evidence is strong, where it's thin, and where your GP needs to be part of the decision.

(05) Questions

Before you buy

Is this medical advice?

No. It's educational. It helps you understand your health and prepare better questions, but decisions about tests, supplements and medicines belong with your GP or specialist.

What format is it?

An online handbook you read in your browser, on your phone or laptop. After checkout, Gumroad emails you a receipt with your licence key; paste it on the unlock page and every chapter opens. [Shweta to confirm: PDF page count, and whether updates are included.]

I'm not in Australia. Will it apply to me?

It's written for South Asian women in the UK, US, Canada and Australia. Test names and how you request them vary, and the handbook covers that.

I'm vegetarian. Will the eating days work for me?

Familiar food is the starting point. [Shweta to confirm: vegetarian and non-vegetarian sample days.]

How is this different from the free Substack?

The Substack essays are free and always will be. The handbook is the structured, edited system: the blood panel, eating days and advanced section in one place.

What's the refund policy?

There's a 30-day money-back guarantee. If the handbook isn't for you, reply to your Gumroad receipt within 30 days of buying and you'll get a full refund.
