People living with HIV in rural South Africa who take the medication TLD experience weight gain, but a Gram Research analysis of interviews with 26 affected patients reveals they want to manage their weight through exercise and medication rather than diet changes. Importantly, they fear that rapid weight loss would make them appear sick, and they worry about judgment from family and friends—cultural concerns that standard weight loss programs often ignore.
A new HIV medication combination called TLD is saving lives in South Africa, but it’s causing an unexpected problem: weight gain. Researchers talked to 26 people living with HIV in rural South Africa who had gained weight while taking this medication. They discovered something surprising: people wanted to be healthier but worried that losing weight too quickly would make them look sick. They also feared judgment from family and friends. The good news? People were interested in exercise and medical treatments to manage their weight, even if they weren’t interested in changing their diets. This research shows doctors need to understand local beliefs about body size when helping patients stay healthy.
Key Statistics
A qualitative study of 26 people living with HIV in rural KwaZulu-Natal, South Africa found that while participants understood health risks of excess weight, they rejected the idea of becoming thin because they associated thinness with HIV-related illness.
Among 26 overweight or obese people living with HIV taking TLD medication, participants expressed strong interest in exercise-based and pharmacologic weight management interventions but had little interest in diet modification strategies.
Research with 26 HIV patients in rural South Africa revealed that concerns about stigma from family and friends if they experienced rapid weight loss were a significant barrier to pursuing standard weight loss approaches.
The Quick Take
- What they studied: Why people living with HIV in rural South Africa gain weight after starting a new HIV medication, and what strategies they think would help them manage their weight
- Who participated: 26 adults living with HIV in rural KwaZulu-Natal, South Africa, who were overweight or obese (body mass index of 30 or higher)
- Key finding: People wanted to prevent weight gain but rejected the idea of becoming thin because they associated thinness with illness. They were interested in exercise and medication to manage weight but not in changing their diet.
- What it means for you: If you or someone you know is taking HIV medication and gaining weight, it’s important to talk with your doctor about exercise-based or medical options rather than just diet changes. Understanding why weight gain happens and what feels culturally acceptable is key to finding solutions that actually work.
The Research Details
Researchers conducted one-time, in-depth interviews with 26 people living with HIV who had gained weight while taking a medication combination called TLD (tenofovir disoproxil fumarate, lamivudine, and dolutegravir). This is a qualitative study, meaning the researchers focused on understanding people’s thoughts, feelings, and experiences rather than just measuring numbers. They asked open-ended questions to learn how people felt about their weight, what they believed caused weight gain, and what strategies they thought would help. The researchers used a framework called the Causal Continuum Model for Obesity to organize and understand the information people shared.
This research approach is important because it goes beyond just measuring weight changes. By listening to what people actually think and feel, researchers can understand the real barriers to weight management. In this case, they discovered that cultural beliefs about body size—like the idea that thinness means sickness—are just as important as the medical facts. This kind of understanding helps doctors create solutions that people will actually use.
This study has some important strengths and limitations to know about. The strength is that it gives a detailed, honest picture of what people in this specific community think and experience. The limitation is that it only included 26 people from one rural area in South Africa, so the findings may not apply to everyone living with HIV everywhere. The study was also conducted at one point in time, so it doesn’t show how people’s views might change over time. Additionally, the researchers didn’t measure actual weight changes or health outcomes—they only collected people’s perspectives.
What the Results Show
The most striking finding was a contradiction in what people wanted: they expressed a desire for a smaller body size and better health, but they simultaneously rejected the idea of becoming thin. They associated thinness with being sick from HIV, so rapid weight loss would actually worry them and their families. This is a crucial insight because it means that standard weight loss advice might backfire in this community.
Participants also showed strong awareness of health risks. They consistently connected larger body sizes with increased risk of high blood pressure, diabetes, and other serious health problems. This means they understood the medical reasons to manage their weight—they just needed approaches that fit their cultural values.
When asked about solutions, participants showed clear preferences: they were interested in exercise-based interventions and medications to help with weight loss or prevent weight gain. However, they had very little interest in changing their diet. This preference is important information for doctors designing weight management programs.
The research revealed that stigma and social judgment were major concerns. People worried that family and friends would judge them if they lost weight too quickly or dramatically. This suggests that weight management programs need to involve family members and address community attitudes, not just focus on the individual. The study also showed that people distinguished between wanting to be healthy and wanting to look a certain way—they cared more about health outcomes than appearance.
According to Gram Research analysis, this study adds important cultural context to what was already known: TLD medication does cause weight gain in many people. Previous research had documented the weight gain itself, but this study explains why people might not follow standard weight loss advice. It shows that one-size-fits-all approaches don’t work when cultural beliefs about body size are different from Western medical perspectives. The finding that people prefer exercise and medication over diet changes is also notable, as it differs from typical weight management recommendations in other populations.
This study only included 26 people from one rural area, so the results may not apply to all people living with HIV or to urban areas. The researchers only talked to people once, so they couldn’t track whether people’s views changed over time or whether they actually tried the strategies they said interested them. The study didn’t measure actual weight changes or health outcomes—it only captured what people said they thought and wanted. Additionally, the study focused on people who were already overweight or obese, so it doesn’t include perspectives from people who didn’t gain weight on TLD medication.
The Bottom Line
If you’re living with HIV and taking TLD medication, talk with your doctor about exercise programs or weight management medications rather than focusing only on diet changes. Work with your healthcare provider to set realistic goals that feel culturally appropriate to you and your family. Consider involving family members in your health plan, since their support and understanding matter. The evidence suggests that combining medical support with exercise is more likely to work than diet-only approaches in this context. Confidence level: Moderate, based on qualitative research from one community.
This research is most relevant to people living with HIV in Southern Africa who are taking TLD medication and experiencing weight gain. It’s also important for healthcare providers, public health officials, and HIV treatment programs in rural areas who want to design weight management programs that actually work for their communities. Family members of people living with HIV should also pay attention, since the research shows that family support and attitudes significantly influence weight management success. The findings may also apply to other communities with similar cultural beliefs about body size and health.
Weight gain from TLD medication typically happens gradually over months, so weight management efforts also take time. You shouldn’t expect dramatic results in a few weeks. Exercise benefits usually appear within 4-6 weeks in terms of how you feel, but visible weight changes may take 2-3 months or longer. If you’re using medication to help with weight management, your doctor can tell you what timeline to expect. The most important thing is consistency over time rather than quick results.
Frequently Asked Questions
Why do people gain weight when they start taking HIV medication?
The TLD medication combination used to treat HIV can cause weight gain as a side effect in many people. Researchers aren’t entirely sure why this happens, but it’s a known effect of this particular medication. It’s not because people are eating more—it’s a biological effect of the drug itself.
What do people living with HIV think is the best way to manage weight gain from medication?
According to a study of 26 people in South Africa, most preferred exercise-based approaches and weight management medications over changing their diet. They were concerned that diet-only approaches wouldn’t work and that rapid weight loss would make them look sick.
Is it safe to lose weight quickly if you’re living with HIV?
Rapid weight loss can sometimes cause health problems for anyone, including people with HIV. It’s better to aim for gradual, steady weight loss of 1-2 pounds per week through exercise and medical support. Talk with your doctor about a safe plan for your specific situation.
How can family members support someone living with HIV who’s trying to manage their weight?
Research shows that family support matters significantly. Understand that your loved one wants to be healthy, not necessarily thin. Encourage exercise together, avoid judgment about their body, and help them see weight management as a health goal rather than an appearance issue.
What’s the difference between this study and other weight loss research?
This study focused on understanding what people actually think and want, rather than just measuring weight changes. It revealed that cultural beliefs about body size are just as important as medical facts when designing effective weight management programs.
Want to Apply This Research?
- Track weekly exercise minutes and type (walking, running, strength training, etc.) rather than focusing only on weight. Set a goal like 150 minutes of moderate activity per week, which is the standard health recommendation. This shifts focus from appearance to health behaviors and fitness improvements.
- Use the app to schedule exercise sessions and get reminders, since the research shows people are interested in exercise-based approaches. Create a simple log where you record what type of exercise you did and how you felt afterward. Share your exercise goals with a family member through the app so they can support you and understand you’re working toward health, not appearance.
- Track exercise consistency over 8-12 weeks rather than daily weight fluctuations. Monitor how your clothes fit, your energy levels, and how you feel during physical activity. If you’re also using medication to help with weight management, log any side effects or changes you notice. Review your progress monthly with your healthcare provider rather than obsessing over weekly weight changes.
This research describes perspectives and experiences from one community in rural South Africa and should not be considered medical advice. If you are living with HIV and experiencing weight gain or have concerns about your medication, please consult with your healthcare provider or HIV specialist. They can discuss your individual situation, potential medication adjustments, and safe weight management strategies tailored to your health needs. Do not stop taking your HIV medication without medical guidance. This article summarizes qualitative research about patient perspectives, not clinical trial results about treatment effectiveness.
