Quick Answer
Jennifer Stone did not report a weight loss amount, because this is not a weight loss story. At age 20, she gained 60 pounds in three months, along with blurry vision and deep fatigue. That sudden change was the first sign of a serious illness, not the result of a diet or a lifestyle choice. After about four years of misdiagnosis, doctors finally diagnosed her with adult onset type 1 diabetes, a condition sometimes called LADA. She went on to become an emergency room nurse in Los Angeles.
So if you searched for a number of pounds she lost, here is the honest answer. No documented loss amount exists. She has never announced one. What she has shared, in detail, is the weight gain that changed her life, the long road to a correct diagnosis, and the nursing career that grew out of it. That is the story this article tells.
Who Jennifer Stone Is
Most people first met Jennifer Stone as Harper Fink, later Harper Finkle, the quirky best friend on Disney Channel’s Wizards of Waverly Place. She played the role across the show’s four seasons, opposite Selena Gomez, and grew up on television sets. By the time she was old enough to drive, she already had a long list of acting credits.
But acting was only ever half of her plan. College was always on her roadmap. She started out as a psychology major, moving between auditions and classes, living the busy life of a young working actress in Los Angeles. Then, at 20, her body began sending signals she could not ignore, and everything changed.
Today she splits her time between two careers that could hardly be more different. She still acts, because acting brings her joy. She also works 12 hour shifts in a Los Angeles emergency room, because nursing lets her do for other people what she once needed done for herself. She says it simply herself. Acting is for her, and nursing is what she gets to do for other people.
The 60 Pounds in Three Months
Stone told her story to Healthline for its Diagnosis Diaries series, in honour of Diabetes Awareness Month. As an active 20 year old, bouncing between auditions and college classes, she started noticing that she tired far more easily than usual. Going to the grocery store would knock her out for the rest of the day. She told Healthline she was exhausted from doing the simplest things.
Then her vision changed. She started getting blurry vision, to the point where people’s faces, even right in front of her, were just shapes. She could tell it was a face, she said, but she could not really tell anything else. And then came the weight change that made her act. She inexplicably gained 60 pounds in three months.
That number deserves context, because it is easy to misread. This was not gradual weight gain over years. It was sudden, rapid, and paired with exhaustion and vision problems. Stone herself knew something was wrong. She said it plainly. Something was up, and she had to go to the doctor.
It is also the opposite of the usual diabetes story most people know. Type 1 diabetes is typically linked with unintentional weight loss, as the body, unable to use glucose for energy, starts breaking itself down. Type 2 diabetes usually develops in older adults with a longer history of obesity. Stone was 20, active, with no history of obesity, and she was gaining weight fast. She did not fit either box. As she put it, she was not a cookie cutter diabetic, and nobody is.
Four Years Without an Answer
What followed was about four years of going from doctor to doctor in search of answers. Nobody could seem to agree on a diagnosis. Stone was put back and forth between type 2 and type 1, type 2 and type 1, with no resolution. She was put on and off different type 2 diabetes medications, and nothing was helping.
Some of that time was spent being blamed for the failure of treatments that were never right for her condition. She told Healthline about doctors who played what she called the blame game, telling her she must be snacking, because the medication should have been working. When a treatment does not work, it is easy for a patient to start doubting herself. Stone learned the opposite lesson. The hardest part of being diagnosed, she said, is the middle, when you do not know what is going on with your body and you do not know how to fix it. It is the not knowing, the not feeling heard, the not feeling seen, and the feeling alone in it, that can be the most challenging.
She cried in a few doctors’ offices, she said, just out of sheer frustration. That detail matters, because it is the human cost of misdiagnosis. Four years is a long time to be told, in effect, that your body is a mystery and your reports cannot be trusted. It is also a long time to live with untreated or wrongly treated diabetes, a condition that needs daily management for life.
Her experience is not unusual, and that is part of why she tells it. Research cited by Healthline shows that more than half of all new cases of type 1 diabetes occur in adults, not children. Adult onset type 1 diabetes, sometimes called LADA, progresses more slowly than childhood type 1, and its blood tests often show fewer markers of autoimmune disease. The older someone is at diagnosis, the more likely they are to be mistaken for having type 2 diabetes. Stone was young for the adult onset label, but her slower progression followed a similar pattern, and her ambiguous blood tests fit it too.
The Diagnosis That Finally Fit
Eventually Stone found an endocrinologist who figured out what was going on. She did not have type 2 diabetes. She did not have a typical case of type 1 diabetes either. She had adult onset type 1 diabetes, in the pattern often called LADA, latent autoimmune diabetes in adults. In this form of the condition, the immune system attacks the insulin producing beta cells in the pancreas, but it does so slowly, so the pancreas keeps producing some insulin for a time. That is why type 2 medications can seem to work at first, then lose effect as the beta cells fail.
The phone call that delivered the official diagnosis still stung, even after years of waiting. Stone remembered the caller repeating how sorry they were, over and over, as if delivering news of a death in the family. She did not fully grasp what it meant at first. What it meant, in practical terms, was a life as someone insulin dependent.
Once she realised how effective insulin was for a type 1 diabetic, the work became finding the right way to deliver it. She tried insulin pens and insulin pumps. Pumps gave her trouble. The tubing would occlude, or block, within a day or two, and she kept catching the line on everything. She jokes that she is clumsy, but a blocked insulin line is a serious problem, not a funny one. When her endocrinologist introduced her to a smart insulin pen, the InPen, paired with a continuous glucose monitor, she finally found a system that fit her life. An app on her phone helps calculate her insulin doses, and she says it helped her keep a much tighter range.
She also had to learn to live with other people’s reactions. At first she would go to the bathroom to give herself an injection. She soon gave that up. She was not about to spend the rest of her life in a bathroom, she said, and people would have to get used to it. Friends, she found, mostly wanted to learn. They asked how it all worked, what would change, and what they should do in an emergency like severe low blood sugar. Some were a little too careful with her, treating her as if she might break. She told them plainly that she was not going to break.
From Patient to Nurse
The diagnosis changed her career plans. She had started college as a psychology major, but after the diagnosis she switched gears. She remembers thinking that she had this new thing in her life, a diagnosis she was still trying to understand, and that nursing was a way to further understand her own body while also making sure she was a positive influence on other patients’ experiences.
That decision was shaped by everything she had lived through. In those first four years seeking a diagnosis, she encountered a wide variety of health care providers, and she experienced the ups and downs of navigating the health system from a patient’s point of view. She believes that gives her a level of understanding that is hard to have unless you have been a patient, unless you have been through what it is like to be seen and heard, and what it is like not to be seen and heard.
She particularly loves her diabetes patients. When she has her glucose monitor or her smart pen visible, she tells them about it, comparing colours and sharing a laugh. It is a small moment of connection, but it comes from a real place. She knows what it is like to sit on the other side of that conversation.
Her support system mattered throughout. Her mother stood by her through it all, helpful especially in the beginning, when the learning curve felt so high. She remembers a short session with a diabetes educator that left her head spinning with information overload. Friends who wanted to learn everything helped too. And later, connecting with the type 1 diabetes community, including work with Beyond Type 1, the advocacy organisation founded by Nick Jonas, made the feeling of being alone fade. That was when that feeling of being alone dissipated, she said, because the diabetes community is unbelievable.
Why This Is Not a Weight Loss Story
It is worth stating the point of this article one more time, clearly. Jennifer Stone’s story is about a 60 pound weight gain, not a weight loss. The gain was a symptom, and a confusing one, because it did not match the textbook picture of either type of diabetes. Treating her story as a weight loss journey would get the facts backwards and would miss the point she herself makes.
Her advice to others comes from those four years. Trust your instincts. Do not second guess yourself or assume you must be getting it wrong. Learn to stand up for yourself, ask questions, and say no when something does not sound right. She calls herself a recovering perfectionist, and she says you cannot be a perfectionist with diabetes. Just take it one step at a time, learn one skill at a time, and accept that you are not going to be perfect. You just do the best you can for that day, and then move on to the next day.
There is also a broader lesson in her story for anyone who searches celebrity weight terms. A sudden, unexplained change in weight, in either direction, especially paired with fatigue, vision changes, thirst, or frequent urination, is a reason to see a doctor, not a reason to copy a celebrity routine. Stone’s own story shows why. The change meant something was wrong, and it took four years to find out what. No diet article would have helped her. A correct diagnosis did.
Conclusion
Jennifer Stone gained 60 pounds in three months at age 20, alongside exhaustion and blurry vision. After about four years of misdiagnosis, she was diagnosed with adult onset type 1 diabetes, in the pattern often called LADA, and she turned that long patient experience into a nursing career in a Los Angeles emergency room. No documented weight loss amount exists, and this article invents none. Her story is about gaining answers, not losing pounds.
