Weight loss advice that ignores your health history isn't very useful advice. If you're managing a chronic illness, an autoimmune condition, or a rare genetic disorder, the "eat less, move more" formula often needs real adjustment — some medications cause weight gain, some conditions make exercise painful or risky, and some diets that work for the general population can be actively unsafe for you. We've put together condition-specific guides so you can find advice that actually applies to your situation, written with South African healthcare access, medical aid realities, and local food culture in mind.
Please note: These guides are educational starting points, not medical advice. Always speak to your doctor, dietitian, or specialist before changing your diet, starting exercise, or adjusting medication — especially where a chronic condition is involved. What's safe for one person with a condition may not be safe for another.
Metabolic and Hormonal Conditions
Hormones and metabolism play a huge role in how easily (or not) your body loses weight. These guides cover the most common metabolic and endocrine conditions we hear about from South African readers.
- Weight Loss With PCOS - inositol, metformin and GLP-1 options explained
- Weight Loss With Type 2 Diabetes - breaking the blood-sugar-weight cycle
- Weight Loss With Prediabetes - reversing the trend before it progresses
- Weight Loss With Hypothyroidism - working with a slower metabolism
- Weight Loss With Hashimoto's - managing autoimmune thyroid disease
- Weight Loss With Cushing's Syndrome - cortisol, weight gain and treatment
Autoimmune and Inflammatory Conditions
Chronic inflammation can affect appetite, energy levels and how your body stores fat. These guides look at safe, sustainable approaches for autoimmune and inflammatory diagnoses.
Heart, Kidney and Cardiovascular Conditions
Weight and cardiovascular health are closely linked, but restrictive dieting isn't always appropriate when your heart or kidneys are already under strain. These guides explain safer approaches.
Digestive and Liver Conditions
Gut and liver health directly affect how your body processes food, so a one-size-fits-all diet rarely works here. These guides cover the digestive and liver conditions we're asked about most.
Mental Health and Neurological Conditions
Mood, medication side effects, sleep and neurological conditions all influence appetite and motivation. These guides take a compassionate, practical look at weight management alongside mental and neurological health.
Sleep, Bone and Other Chronic Conditions
Rare and Genetic Conditions
We've also built out an extensive library covering dozens of rarer inherited metabolic and genetic conditions, from Prader-Willi syndrome to hereditary metabolic disorders. If you're living with a rare diagnosis, search our site by condition name — there's a good chance we've covered it.
A Note on Approach
A few things hold true across almost every condition on this list:
- Get a diagnosis-specific plan: A dietitian who understands your condition can build a plan around your medication, lab results and symptoms — not just a generic calorie target.
- Medication matters: Some chronic medications (certain antidepressants, steroids, insulin, some epilepsy drugs) are linked to weight gain. Never stop or change a prescribed medication to manage weight without speaking to your prescriber first.
- Movement can still help: Even where a condition limits high-intensity exercise, gentle movement like walking, swimming or stretching often remains safe and beneficial — check with your healthcare provider for condition-specific limits.
- South African access matters: Medical aid formularies, NHI rollout, and specialist availability all affect what's realistic. Our GLP-1 medication guide covers what's currently accessible locally.
When to see a doctor immediately: Unexplained rapid weight loss or gain, new or worsening symptoms, or any concerning change alongside a diagnosed condition should be discussed with your doctor promptly rather than managed through diet alone.
