Lipodistrofia: a doença rara que impede o corpo de reter gordura

Arthur Queiroz is 34 years old and has the body composition of an elite athlete—extremely low body fat, visible musculature, the kind of physique most people spend years in gyms trying to achieve. He did not choose this. He was born this way, the result of a genetic mutation that left him with almost no fat cells at all.

He has lipodistrofia, a rare condition so uncommon that doctors estimate it affects roughly one person per million worldwide. In Arthur's home state of Rio Grande do Norte in Brazil, however, the prevalence is thirty-two times higher—a legacy of Portuguese colonial settlement patterns and generations of marriages between relatives that concentrated a particular genetic mutation in the region's bloodline. The condition is also called Berardinelli syndrome, named after the endocrinologist who first described it in 1954.

What makes Arthur's condition paradoxical is this: while his body looks like it belongs to someone obsessed with fitness, he lives under dietary restrictions as severe as those imposed on someone with obesity. His body cannot store fat properly. The fat he consumes does not accumulate where it should—in adipose tissue—so instead it deposits in his liver, pancreas, and muscles, causing inflammation, metabolic dysfunction, and serious disease. He has developed diabetes. He cannot drink alcohol because his liver struggles to process fat. He cannot eat freely. His hunger never fully stops because his body produces almost no leptin, the hormone that signals satiety to the brain. He feels hungry even when he should feel full.

Arthur was diagnosed young, which saved him from years of misdiagnosis. His maternal grandmother had a son with the same syndrome, so when the physical signs appeared in Arthur's childhood—the extreme leanness, the visible musculature—his family recognized what was happening. But early diagnosis brought its own pain. His mother sold fried snacks for a living, and Arthur would watch other children eat them while he was forbidden. At school, he hid his friends' lunch money so he would not have to watch them buy candy from the cafeteria. He was sometimes excluded from birthday parties. In adolescence, his inability to drink alcohol made him seem antisocial. He received years of psychological support, speech therapy, and physical therapy to address speech difficulties and the way he walked on his toes.

Women with the condition, Arthur observes, face even harsher judgment. Because they lack fat, their bodies appear more muscular and defined—a physique society often reads as masculine. When people see a woman with lipodistrofia, they see something that violates their image of what a female body should be, and they judge accordingly.

There is no cure for lipodistrofia. There is no diet that can reverse it. Treatment focuses on managing the metabolic chaos it creates—controlling blood sugar, preventing heart disease, protecting the liver and kidneys. In 2023, Brazil approved metreleptina, a synthetic version of leptin that can help reduce hunger and improve metabolic function. But access remains limited; most patients cannot get it. The real treatment is discipline: strict nutrition, constant exercise, vigilant medical monitoring. For Arthur, this has meant avoiding serious complications that have devastated others with the same diagnosis—diabetes requiring insulin, liver cirrhosis, kidney failure requiring dialysis.

Arthur is now a civil servant with a stable income. He lives independently, travels frequently, and is pursuing a doctorate in Education, Science, and Mathematics. Last year, he spent six months in Portugal on an academic exchange. He describes his life as good, and he is grateful for it. He acknowledges that his condition demands constant attention, that it could have gone much worse, that many others with lipodistrofia have faced far graver complications. He hopes the disease becomes better known, that diagnoses happen earlier, that what is different becomes more recognized. For now, he carries on—managing a body that looks like an athlete's but lives under the constraints of a serious metabolic disease, a paradox that few people understand.
