Structured diet plans provide clear guidance and take the guesswork out of weight management. Our collection of evidence-based diet plans offers options for different caloric needs, dietary preferences, and health considerations. Each plan includes complete 7-day meal plans with nutritionally balanced recipes and shopping lists to simplify your weight loss journey.
Every plan below is built around ingredients readily available at South African supermarkets, with kilojoule counts rather than just calories, so you can shop and track using labels the way they're printed here at home. Whether you're feeding a household on a tight rand budget or need a plan flexible enough to work around load shedding and braai weekends, there's a starting point below — and you can always move between plans as your needs change.
Note: Before starting any calorie-restricted diet, consult with a healthcare professional, especially if you have existing health conditions or are taking medications.
❄️ Choosing a Diet Plan for Winter
Appetite naturally increases in colder months, and comfort-food cravings can derail even a well-chosen plan. A couple of winter-specific pointers:
- If you're on the 5000 kJ plan and finding it tough in winter, it's fine to step up to the 7600 kJ plan temporarily rather than abandoning structure altogether.
- Warm, high-fibre meals (soups, potjies, stews) fit all three kilojoule-controlled plans below — just swap heavy starches for extra vegetables.
- Load shedding-friendly batch cooking works well with the High Fibre Diet Plan, since fibre-rich meals reheat and store well.
As always, check with a doctor or dietitian before changing your calorie target, especially if you're managing a medical condition.

Ozempic Diet GuideChoosing the Right Diet Plan
When selecting a diet plan, consider these factors:
- Energy Needs: Based on your height, weight, age, gender, and activity level
- Health Considerations: Any existing medical conditions or nutritional concerns
- Food Preferences: Cuisines and ingredients you genuinely enjoy
- Lifestyle Factors: Time for food preparation, social dining situations, etc.
- Previous Experience: What has and hasn't worked for you in the past
Important: The most effective diet plan is one you can adhere to consistently. Consider starting with a more moderate approach (e.g., 7600 kilojoule) and adjusting based on your results and experiences.
❓ Diet Plan FAQs
Which kilojoule diet plan should I start with?
Most sedentary adults do well starting at 7600 kJ (roughly 1800 calories) and adjusting based on results after 2-3 weeks. The 5000 kJ plan is more aggressive and better suited to shorter or less active individuals under guidance, while the 10000 kJ plan suits very active people or those in a maintenance phase.
Can I switch between diet plans?
Yes — many people move between kilojoule levels as their activity, weight, or life circumstances change. There's no harm in adjusting your target as long as changes are gradual and you're still eating a nutritionally balanced diet. See our Nutrition guide for the balance principles that apply across all plans.
Are these diet plans safe if I have a medical condition?
The plans on this page are general guidance, not personalised medical advice. If you have diabetes, heart disease, kidney issues, or are pregnant or breastfeeding, speak to your doctor or a registered dietitian before starting any structured calorie-controlled plan — our Medically Supervised Diets page explains when professional oversight is especially important.
How do these plans work alongside Ozempic or Mounjaro?
GLP-1 medications reduce appetite significantly, so a very low-calorie plan isn't usually necessary or advisable alongside them — the focus shifts to nutritional adequacy despite eating less. See our Ozempic Diet Approach section above and always follow your prescribing doctor's guidance.
