In just one Instagram post, Lena Dunham has sent a powerful message about her weight.

Lena Dunham has always been candid about her life.

Now the Girls’ creator has opened up about her own body positive journey on social media.

The 32-year-old posted a side-by-side photo on Instagram, explaining to her fans that she’s happier in the photo on the right.

“On the left: 138 pounds, complimented all day and propositioned by men and on the cover of a tabloid about diets that work. Also, sick in the tissue and in the head and subsisting only on small amounts of sugar, tons of caffeine and a purse pharmacy,” she explained.

“On the right: 162 pounds, happy joyous and free, complimented only by people that matter for reasons that matter, subsisting on a steady flow of fun/healthy snacks and apps and entrees, strong from lifting dogs and spirits.”

The actress explained that although she sometimes looks at the left picture longingly, she knows what it took to get herself there brought her to her “proverbial knees”.

“As I type I can feel my back fat rolling up under my shoulder blades. I lean in,” she added.

Last year Dunham took aim at a magazine that was championing her weight loss, by using a photo of her, alongside the coverline “20 diet slim down tips stars are using”.

In response, Dunham shared the real 20 reasons she’d lost weight.

In true Dunham style, though, her list was a little different to what the magazine was offering up, swapping green smoothies and no carbs after 9pm for things like, “anxiety disorder” and “sleeping 19 hours a day”.

The actor’s full list reads:

1. Anxiety disorder

2. Resultant constant nausea

3. An election that reveals the true depths of American misogyny

4. Constant sweaty dreams of dystopian future

5. Abdominal adhesions pinning ovary below uterus 

6. Baseless but still harrowing threats to physical safety online and through mail

7. Watching institutions you love from Planned Parenthood to PBS be threatened by cartoon mustache-twirling villains

8. Finally realising superheroes aren’t real (specifically the X-Factor, really thought they’d handle this)

9. Marching your ass off

10. A quiet rage that replaces need for food with need for revenge

11. Sleeping 19 hours a day

12. Realising that even the liberal media wants dem clicks no matter what

13. Worrying ceaselessly about the health and safety of women you know and women you don’t

14. Realising who your real friends are

15. Having to switch from Uber to Lyft (lots of calories burned trying to understand a new app, then even more trying to understand if the conflict was resolved)

16. Bladder spasms, urinary frequency and urgency 

17. Having your phone number leaked and violent images texted to your phone by randos under names like VERYFATCHUCKYBOY@creepz.com

18. Keeping your back arched against the wind

19. Um, who the f*ck cares?

20. I have no tips, I give no tips, I don’t want to be on this cover cuz it’s diametrically opposed to everything I’ve fought my whole career for and it’s not a compliment to me because it’s not an achievement thanks.
