Muscle is Not a Trend, Why ‘Skinny Culture’ is a Biological Disaster

I hoped we had moved past this as a society, but the "waif" look is back, and honestly, it is absolute rubbish. It’s the 90s heroin chic aesthetic all over again and it’s not just an eye-roll moment, it’s actually dangerous.

I’ve come across influencers lately actually selling "muscle reduction" plans. Read that again. Muscle reduction. In what world is intentionally making yourself weaker a "fitness" goal? It’s a biological disaster, and a direct attack on your future independence.

Think about this for a second. If you’re walking down the street and you see an animal with its ribs poking out, sunken eyes, and hip bones jarring against its skin, what’s your first thought? You feel sorry for it. You realise, instinctively, that the animal is in a state of failure to thrive. You know it’s weak, it’s vulnerable, and it’s probably ill.

In nature, emaciation is a massive red flag. It means the creature is dying. So why on earth are we being told that looking like this is "fashionable" for women? The fashion industry and social media have taken a body that is visibly running on empty and repackaged its fragility as an aspirational goal.

For the vast majority of people, this "extra skinny" look isn't just hard to get it's unobtainable. We are all born with a specific bone structure and a biological "set point." To force a body that is naturally athletic or curvy into a waif-like frame requires more than just discipline. It requires a level of starvation that stops your life in its tracks.

Most of what you see on social media is a mix of genetics, professional lighting, specific posing, and, more often than not, digital manipulation. Trying to look like this is a recipe for failure. You are fighting against your own DNA, the cost of trying to beat it is your health and happiness.

Fashion has always been a way to keep women weak. From the Victorians fainting in corsets to foot-binding, trends have a long, grim history of making sure we can’t move properly or take up too much space. But the worst part is how it messes with your head. It’s hard to stand up for yourself, lead a team, or be a force in the world when you haven’t had a decent meal in three weeks. A body that is chronically under-fuelled is a body that is easy to manage. It keeps us quiet, tired, and focused on the scale instead of our actual power.

The problem is that the fashion industry treats our bodies like seasonal trends. One minute curves are being marketed, and the next, they’ve decided that being practically skeletal is back in style. If you treat your body like an accessory, you will never be finished. You’ll spend your entire life staring in the mirror trying to aesthetically fix a something that isn’t even broken. This constant shifting of how the fashion industry is pushing you to look. It robs you of the ability to see your body for all the incredible things it does and leaves you obsessing over whether your reflection matches a trend that will (hopefully) be gone by next year anyway. It's an endless cycle of self-critique where the only real winner is the industry selling you the cure.

As a PT, I see the damage this aesthetic does. People think they’re just losing weight but they could actually hitting a state of Relative Energy Deficiency (RED-S). Where your body doesn't just burn fat when you starve it, it cannibalises itself to stay alive.

Muscle Wasting: Your body starts eating its own muscle for fuel because muscle is expensive to keep. And yes, that includes your heart muscle.

The Bone Crisis: This is the big one. If you’re under-fuelling, your bone density drops off a cliff. You might look skinny, but you’re setting yourself up for a hip replacement at 60. You are literally making your skeleton porous for the sake of a trend.

The Brain Fog: Your brain uses 20% of your total daily energy. When you don’t eat enough, your brain enters survival mode. You get anxious, you get irritable, and you lose your personality.

Muscle keeps you independent and mobile as you age. Intentionally losing it is like burning your pension because you like the way the fire looks. It’s short-sighted, it’s foolish, and it’s dreadful. When you're 70 and can't get off the toilet by yourself because you have no leg strength, or when a simple trip results in a shattered pelvis because you turned your bones to dust trying to shrink.

We need to stop trying to disappear. We should want to be healthy, powerful, resilient, capable, and vibrant. Strength isn't an "elective" for people who want to look like bodybuilders, it’s a fundamental requirement for being a functioning human being.

Forget the muscle reduction and extra skinny rubbish. Stop trying to fit into a trend that wants you weak and manageable. Your body is not an accessory. Start fuelling it, start building it and appreciate it for all the amazing things it can do.

Enough with shrinking. Click here to start building real, lasting strength.
