The bodies on your feed

You open Instagram for a second. A woman with a tiny waist and perfect curves. A man with a six-pack, huge arms and shoulders like a door frame. Another one. And another. You close the app, catch your reflection in the window and think: everyone looks like that except me. But do they? And is that really what anyone wants?

Two ideals, one feed

Social media has a very clear idea of the "perfect" body, and it's different for each sex.

For women, the ideal has moved from simply thin to "slim but curvy": a flat stomach and small waist, with a large bust and a round, lifted bottom. It's a combination very few bodies have naturally, which is one reason why fillers, implants and "BBL" surgery became so popular.

For men, it's lean and very muscular: visible abs, big arms, a broad chest and shoulders. Again, it's a look that usually takes years of training, a very strict diet at the time of the photo and, for some, substances that don't appear in the caption.

Both sexes see both ideals. So the feed doesn't only tell you how you should look. It also quietly tells you what the other sex is supposed to look like.

How the "perfect" photo is made

Most of the bodies you see are real people, but the photos are not snapshots. Influencers find the one angle that lengthens the legs or shrinks the waist. They pose to tense the stomach, arch the back or push the hips to the side. Men "pump up" with push-ups or weights just before the camera comes out, and some cut back on food and water before a shoot to look leaner. Then come good light, filters, editing apps that can slim a waist or widen shoulders in seconds, and the decision to post one picture out of fifty.

The result is a body that the same person doesn't have most of the day. Fitness influencers themselves have shown this with "Instagram vs reality" posts: the same body, posed and edited on one side, relaxed and natural on the other. The difference can look like two different people.

What it does to how you see yourself

This has been tested in experiments, not just surveys. In Australia, young women who looked at Instagram "fitspiration" photos for a few minutes ended up in a lower mood and less happy with their bodies than women who looked at travel photos. In a study of 300 young men aged 18–30, those who saw bare-chested, muscular influencers felt less satisfied with their own bodies than men who saw clothed fashion photos or scenery.

A 2021 analysis that combined dozens of these experiments found that looking at "ideal" bodies had a moderate negative effect on how people felt about their own. Studies that followed people over months found only a very small link with how much they used social media overall. So it's less about how many hours you scroll and more about which bodies fill your feed. The algorithm learns which bodies make you stop scrolling, and then shows you more of them.

The good news is that knowing the trick helps. When women saw "Instagram vs reality" posts instead of the polished versions alone, their body dissatisfaction went down. Seeing how a photo is made takes away some of its power.

What we think the other sex wants, and what it actually wants

Here's the most surprising part. In a UK study, 169 young women and men adjusted body images on a computer to show what they found most attractive in the other sex, and what they thought the other sex wanted from them.

Both got it wrong in the same direction. Women thought men wanted women thinner than men actually did. Men thought women wanted men more muscular than women actually did. And the bigger the misjudgement, the more unhappy people were with their own bodies.

In other words, a lot of the pressure we feel isn't coming from real partners. It's coming from an exaggerated picture of what they want, and feeds full of extreme bodies are a good place to learn that picture.

The same exaggeration can work the other way, when we judge real partners against bodies we only know from screens. Someone who looks great in real life, at a party, at the beach or next to you in bed, can start to seem "ordinary" next to a feed of edited highlights. That comparison is unfair to them and to you. Most people in real life, including those influencers on a normal Tuesday, don't look like their best photo.

The bottom line

The bodies on your feed are a mix of rare genetics, hard work, good lighting, posing, editing and sometimes surgery, chosen because they stop your thumb. They aren't a fair standard for you, and they aren't a fair standard for the people you date. And most of the time, real partners want much less "perfection" than we think. A few things help:

Clean up your feed. Mute or unfollow accounts that regularly leave you feeling worse, and follow some that show ordinary, varied bodies doing things, not just posing.

Remember the making-of. When a body looks impossible, think of the angle, the pump, the light and the edit behind it.

Check your assumptions. If you believe the other sex wants a certain body, ask yourself where that idea came from. Research suggests it's probably more extreme than reality.

Look at real people. Spend time with friends and partners offline, where bodies move, laugh and change through the day.

If thoughts about your body take up a lot of your day, or you're restricting food, over-exercising or using substances to change how you look, talk to a doctor or psychologist. Eating disorders and body image problems affect men and women, and they are treatable.
