Author’s note: The patient described in this post asked that her details be altered to protect her anonymity. “Julie’s” story is similar to many in the literature, meaning that her weight loss journey involved diet, exercise, and medications. Please consult a licensed care provider before embarking on any weight loss experience.
Julie came to my office via an unusual route. I first met her at my CrossFit gym and started a conversation with her. When Julie heard that I was a physician, she asked me why she had joined the gym. I asked Julie if she had consulted a physician regarding weight loss, and she admitted she had not. I wondered if she would prefer to ask for a referral to see me so that I could guide her along the way.
Julie’s Weight Loss Journey
Julie is a 39-year-old single mother of two energetic children, ages 12 and 8. Juggling her job as a nurse while raising her kids, Julie often put her own health on the back burner. Over time, her weight steadily increased as she relied on quick, convenient meals, sugary coffee drinks, and late-night snacks to manage the demands of her hectic life.
At her last check-up, Julie’s doctor gently noted that her weight was beginning to impact her health. Her blood pressure was borderline high, and she was pre-diabetic. This wake-up call, coupled with her constant exhaustion and struggles to keep up with her kids, motivated her to make a change. Julie decided it was time to prioritize her health—not just for herself but for her children as well.
The Importance of Good Nutrition
Julie’s first step was to set realistic goals. She didn’t strive for perfection but focused on making consistent progress. She booked a free consultation with a local nutritionist, who helped her plan quick, nutritious, and family-friendly meals. Together, they created a balanced plan tailored to her lifestyle, emphasizing whole foods, lean proteins, and plenty of vegetables.
To jumpstart her journey, Julie also joined a community-based fitness program designed for busy moms. Twice a week, she attended CrossFit classes while her kids were asleep. On weekends, she often included her children in activities like walks or bike rides, turning fitness into a family affair.
Challenges Along the Way
Like any journey, Julie encountered hurdles along the way. Stress at work sometimes tempted her to reach for comfort food or skip her workouts. On those days, she reminded herself of her "why"—to set a healthy example for her children and to have the energy to fully enjoy life with them.
Julie also leaned on her support network, including her best friend Jenna, who sent encouraging texts, and her CrossFit buddies, who cheered her on during moments of doubt.
Despite her efforts, Julie wasn’t losing weight. While CrossFit is highly physically demanding, even with scaled movements, she felt that her excess weight was holding her back from reaching her fitness goals.
Adding Orlistat to Julie’s Regimen
After careful thought and discussion with Julie, I decided to prescribe orlistat (Xenical). Orlistat is designed to aid weight loss by reducing the absorption of dietary fat. It works as a lipase inhibitor, targeting enzymes in the gastrointestinal tract responsible for breaking down fat. When taken with meals, orlistat binds to these enzymes—specifically pancreatic and gastric lipases—preventing them from hydrolyzing triglycerides into free fatty acids and monoglycerides. Consequently, about 25%–30% of the dietary fat consumed is excreted undigested in the stool rather than absorbed into the body.
I explained to Julie that orlistat is most effective when combined with a reduced-calorie, low-fat diet and regular physical activity. I advised her to aim for a diet where no more than 30% of daily calories come from fat, as exceeding this limit could increase the likelihood of gastrointestinal side effects, such as oily stools, flatulence, and abdominal discomfort. Additionally, I recommended taking a multivitamin containing fat-soluble vitamins (A, D, E, and K) at least two hours before or after orlistat, since the medication can reduce the absorption of these nutrients.
We also discussed the importance of reviewing medical conditions with a healthcare provider. Conditions such as gallbladder disease or chronic malabsorption syndrome may make orlistat unsuitable. I inquired whether Julie was taking other medications, particularly for diabetes or thyroid conditions, as dose adjustments might be necessary.
Side Effects of Orlistat
I also informed Julie about potential side effects. The most common involve changes in bowel habits, particularly during the first few weeks of treatment. These may include oily spotting on clothing, gas with oily discharge, an urgent need to use the bathroom, loose or fatty stools, or difficulty controlling bowel movements. While these effects are usually mild and manageable, I encouraged Julie to reach out to me if they persist or become severe.
In rare instances, side effects can be more serious. I advised Julie to seek immediate medical attention if she experienced symptoms such as hives, difficulty breathing, severe abdominal pain, yellowing of the skin or eyes, dark urine, or extreme fatigue, as these may signal a rare but severe reaction. Although there have been isolated reports linking orlistat to severe liver damage, it remains unclear whether the medication directly caused these issues. Finally, I advised Julie to report any severe side effects to the U.S. Food and Drug Administration’s MedWatch program.
Julie’s weight-loss journey was far from easy—there are no quick fixes when it comes to health and fitness. She made significant changes to her sleep habits, stress management, exercise routine, and diet, ultimately achieving an impressive 95-pound weight loss.
If you or a loved one is considering a weight-loss program, it’s essential to consult a licensed healthcare provider to ensure a safe and effective approach tailored to your needs.
