Weight Loss With HIV in South Africa: What Actually Works (and What to Avoid)
South Africa has the world's largest HIV-positive population — approximately 8.2 million people. If you are living with HIV and struggling with weight changes, you are far from alone. Modern antiretroviral therapy (ART) has transformed HIV into a manageable chronic condition, but it has also introduced a new challenge: significant weight gain. This guide explains why it happens, what is safe to do about it, and how to build a healthy, affordable eating plan that works with your treatment — not against it.
Why HIV and Weight Gain Are Now Linked
For many years, HIV was associated with weight loss and wasting — a condition called HIV-associated wasting syndrome. Thanks to effective ART, this is now uncommon in South Africa when treatment is started on time. The challenge has flipped: weight gain after starting ART is now one of the most common concerns among people living with HIV (PLHIV).
The South African public sector's standard first-line regimen is TLD — tenofovir alafenamide (or tenofovir disoproxil), lamivudine, and dolutegravir. Studies published in the Lancet HIV and presented at IAS conferences show that dolutegravir (the "D" in TLD) is associated with an average weight gain of 3–5 kg over 96 weeks, with higher gains seen in women of African descent. Some individuals gain considerably more.
The mechanisms are still being studied, but dolutegravir appears to:
- Increase appetite via effects on the hypothalamus
- Alter fat storage, particularly abdominal fat
- Allow the body to "return to health" — people who were underweight before ART naturally regain weight, which can overshoot the healthy range
Important: Never stop or change your ARVs because of weight gain without talking to your doctor first. Uncontrolled HIV causes far more harm than extra kilograms. Your doctor can discuss alternative regimens if weight gain is severe.
Lipodystrophy: Fat in the Wrong Places
Older ARVs — especially stavudine (d4T) and the early protease inhibitors — caused lipodystrophy, a redistribution of fat that is distinct from general obesity. Fat is lost from the face, limbs, and buttocks, but accumulates in the abdomen, breasts, and at the back of the neck (the so-called "buffalo hump").
If you were on older regimens and have these symptoms, switching to a modern regimen (under medical guidance) often partially reverses the fat loss in the face and limbs over 12–24 months. Abdominal fat tends to be more stubborn. Exercise — particularly resistance training — is one of the best tools for reducing central fat accumulation in lipodystrophy.
When to Worry: Unintentional Weight Loss
Not all weight changes in PLHIV are ART-related. If you are losing weight without trying while on ART, this is a red flag. Unintentional weight loss of more than 10% of body weight may signal:
- A new or recurrent opportunistic infection (tuberculosis is the most common in SA)
- ART failure (rising viral load)
- Malabsorption or chronic diarrhoea
- Other illness not related to HIV
Report any unintentional weight loss to your clinic immediately — do not try to manage this with diet alone.
A Practical SA Eating Plan for PLHIV
The goal is a high-protein, moderate-carbohydrate, anti-inflammatory diet that is affordable on a South African budget. People living with HIV have slightly higher protein requirements than the general population — aim for at least 1.2 g of protein per kg of body weight per day (for a 75 kg person, that is 90 g of protein daily).
Affordable SA protein sources
| Food | Protein | Typical SA Price |
|---|
| Canned pilchards (400 g tin) | ~48 g | R18–R24 |
| Large eggs (6-pack) | ~36 g (6 eggs) | R22–R30 |
| Dried lentils (500 g) | ~90 g (whole bag) | R22–R28 |
| Dried sugar beans (500 g) | ~110 g (whole bag) | R25–R35 |
| Chicken livers (500 g) | ~50 g | R28–R38 |
| Low-fat plain yoghurt (500 g) | ~20 g | R18–R26 |
Sample day on R80–R100
- Breakfast: Oats (R30–R40/kg) with low-fat milk, a banana. Good pre-ARV base if your medication requires food.
- Lunch: Umngqusho (samp and beans) with morogo (wild spinach/imfino) — a traditional SA meal that is high in fibre, protein, and folate.
- Dinner: Pilchards in tomato sauce on one slice of brown bread, side of roasted butternut.
- Snack: Two hard-boiled eggs or low-fat yoghurt.
- Drinks: Rooibos tea (antioxidant-rich, caffeine-free) and water. Limit sugary cooldrinks.
ARV tip: TLD should ideally be taken with food to reduce nausea and improve absorption. A small meal — even a slice of bread or a banana — is enough. Efavirenz-based regimens are typically taken at night on an empty stomach or with a light, low-fat snack.
What to Reduce or Avoid
- Alcohol — interacts with ARVs, damages the liver (already working hard to metabolise medication), and adds empty calories. Even occasional heavy drinking can affect adherence and viral suppression.
- High-sugar foods — PLHIV have a higher risk of insulin resistance and type 2 diabetes, especially on dolutegravir. Limit white bread, rice, maize porridge in large portions, and sugary drinks.
- Processed meat — polony, viennas, and russians are high in sodium and saturated fat; occasional is fine but not daily.
- Grapefruit — can interfere with some ARVs (especially protease inhibitors) by blocking liver enzymes. Check with your clinic.
- St John's Wort (a popular herbal supplement for depression) — significantly reduces blood levels of several ARVs. Do not use it while on ART.
Exercise: The Most Underused Tool for PLHIV
Multiple studies confirm that regular moderate exercise is safe and beneficial for virally-suppressed PLHIV. Exercise:
- Reduces abdominal fat accumulation from dolutegravir
- Improves CD4 counts and reduces inflammatory markers
- Combats depression and fatigue, which are common in PLHIV
- Reduces cardiovascular risk (PLHIV have higher baseline CVD risk)
- Builds lean muscle mass, improving resting metabolic rate
Getting started safely
If you are newly diagnosed or recently started ART, begin gently. A 20–30 minute walk 5 days a week is an excellent starting point — it costs nothing, can be done in a township or suburb, and is effective. Progress to:
- Weeks 1–4: 30-minute brisk walks daily
- Months 2–3: Add bodyweight resistance — squats, push-ups, lunges (3 sets of 10, 3x per week)
- Month 4 onwards: Consider gym work or community fitness groups; many community centres in Soweto, Khayelitsha, and other areas offer low-cost classes
Do not exercise if: You have a fever above 38°C, are being treated for an active opportunistic infection (TB, PCP, cryptococcal meningitis), have a CD4 count below 100 and feel unwell, or have chest pain or breathlessness at rest. Always get medical clearance if you have not been active in years.
HIV, Obesity, and Cardiovascular Risk in SA
People living with HIV have a 50–100% higher risk of cardiovascular disease than the general population, even when virally suppressed. This is driven by:
- Chronic low-grade inflammation from HIV itself
- ART effects on lipids (some ARVs raise triglycerides and LDL cholesterol)
- Higher rates of smoking in PLHIV communities
- ART-related central fat accumulation increasing insulin resistance
This makes weight management especially important for PLHIV — not for aesthetics, but to protect your heart. Every 5 kg lost reduces systolic blood pressure by 3–5 mmHg and significantly improves fasting triglycerides.
Medicines That May Help (and Ones to Avoid)
Some common weight loss approaches are not appropriate for PLHIV:
- Orlistat (Xenical) — reduces fat absorption; may reduce absorption of fat-soluble ARVs. Discuss with your doctor.
- Semaglutide (Ozempic/Wegovy) — no major interaction with most ARVs, and some HIV clinics in SA are beginning to prescribe it for PLHIV with obesity. Not yet available through the public sector but accessible at Dis-Chem and Clicks with a prescription (R1,500–R2,800/month for starter doses).
- Herbal slimming teas — many contain senna, which causes diarrhoea and can affect ARV absorption. Avoid.
- Over-the-counter appetite suppressants — often interact unpredictably with ART. Always check with a pharmacist before buying anything, even if it seems "natural".

The Bottom Line
Weight gain on ART is real, common, and manageable. A protein-rich diet built on affordable SA staples, 30 minutes of walking most days, limited alcohol and sugar, and an honest conversation with your clinic doctor about your regimen — these four things make the biggest difference. You are not fighting your medication; you are learning to work with it.
Frequently Asked Questions
Why am I gaining weight on ARVs in South Africa?
The standard South African public-sector regimen TLD (tenofovir + lamivudine + dolutegravir) is associated with 3–5 kg average weight gain, particularly in women. Dolutegravir (the "D") appears to increase appetite and may affect fat storage. This is not a sign your treatment is failing — it is a known side effect that your clinic doctor can help manage.
Is it safe to diet while on antiretrovirals?
Yes, with care. Calorie restriction while on ART is generally safe but should be moderate — crash diets are not recommended. Adequate protein (at least 1.2 g per kg body weight per day) is essential to protect lean muscle mass. Always discuss any significant dietary change with your clinic doctor or a registered dietitian.
Can exercise interfere with my HIV medication?
No — regular moderate exercise actually improves CD4 counts, reduces inflammation, and helps with ART-related weight gain. Walking, swimming, and resistance training are all safe. Start gradually and increase intensity over weeks. Avoid exercising if you have a fever, active opportunistic infection, or feel very unwell.
What is the best diet for someone living with HIV in South Africa?
A varied, protein-rich diet built around affordable SA staples works well: eggs, canned pilchards, dried beans and lentils, samp with beans (umngqusho), morogo (wild spinach), sweet potato, and oats. Limit sugar, white bread, and processed foods. Rooibos tea is a good antioxidant-rich beverage choice.
What is lipodystrophy and how does it affect weight?
Lipodystrophy is fat redistribution linked to older ARVs (stavudine, d4T) — fat is lost from the face, arms and legs but accumulates in the abdomen and back of the neck ("buffalo hump"). Older ART regimens caused this more than modern ones like TLD. If you have these symptoms from an older regimen, switching to a newer ARV (with your doctor's guidance) often helps.
How much weight is healthy to lose per month on ART?
Aim for 0.5–1 kg per week (2–4 kg per month) — slow enough to preserve muscle and avoid nutritional deficiencies. Faster weight loss is harder on your immune system and can reduce ARV absorption. If you lose weight without trying, report it to your clinic immediately as unintentional loss can signal an opportunistic infection.
Are there free nutrition services for HIV-positive South Africans?
Yes. Many public-sector HIV clinics have dietitians attached or can refer you. The CCMDD programme handles ART pick-up and can link you to adherence counsellors who address nutrition. ADSA (Association for Dietetics in South Africa) can help locate affordable private dietitians from R600 per session.
Does a higher viral load or low CD4 count affect weight loss ability?
If your viral load is unsuppressed or your CD4 count is below 200, your body is under significant immune stress — this is not the time for aggressive dieting. Focus on eating enough nutritious food to support immune recovery. Once your viral load is undetectable and your CD4 stabilises above 350, safe weight management becomes much more achievable.
