Intermittent fasting (IF) has become one of the world's most popular weight loss strategies — and for good reason. It's simple, flexible, doesn't require calorie counting, and fits easily into a South African lifestyle. Rather than telling you what to eat, IF focuses on when to eat.
Medical Disclaimer: Intermittent fasting is not suitable for everyone. Consult your doctor before starting, especially if you have diabetes, are pregnant, or have a history of eating disorders.
What is Intermittent Fasting?
Intermittent fasting is an eating pattern that cycles between periods of fasting and eating. During fasting periods, your body depletes its glucose stores and begins burning stored fat for energy — leading to weight loss. It also triggers a cellular clean-up process called autophagy, which has numerous health benefits beyond weight loss.
The Most Popular IF Methods
1. The 16:8 Method (Most Popular)
Fast for 16 hours, eat within an 8-hour window. For example:
- Stop eating at 8pm
- Skip breakfast, drink black coffee or water in the morning
- Break your fast at 12pm (noon)
- Eat normally until 8pm
This is the easiest method to start with — you're essentially skipping breakfast and sleeping through most of the fast.
2. The 5:2 Method
Eat normally 5 days a week. On 2 non-consecutive days, restrict calories to 500–600kcal (2100–2500kJ).
- Good for people who struggle with daily fasting
- Fasting days: small meals like soup, eggs, salad
- Popular with South Africans who have busy social weekends
3. The 18:6 Method (Advanced)
A tighter eating window for faster results. Fast 18 hours, eat within a 6-hour window. Better suited to people who have already adapted to 16:8.
4. OMAD (One Meal a Day)
Eat one large meal per day. Very effective but challenging. Only recommended for experienced fasters.
What Can You Have During the Fast?
- ✅ Water (still or sparkling)
- ✅ Black coffee (no milk, no sugar)
- ✅ Plain rooibos or herbal tea
- ✅ Black tea
- ❌ Milk, cream, or sugar in drinks — breaks the fast
- ❌ Fruit juice or cold drinks
- ❌ Any food whatsoever
7-Day 16:8 Intermittent Fasting Meal Plan
Eating window: 12pm – 8pm daily. All times are approximate.
Day 1
- 12pm (Break fast): 2 boiled eggs, avocado on 1 slice rye bread, rooibos tea
- 3pm (Snack): Handful of almonds and a small apple
- 7pm (Dinner): Grilled chicken breast with brown rice and roasted vegetables
Day 2
- 12pm: Greek yoghurt with berries and a sprinkle of granola

Continue rotating balanced meals within your 8-hour window. Focus on whole foods, lean proteins, and plenty of vegetables. Avoid processed foods, fast food, and excessive sugar.
Benefits of Intermittent Fasting
- Weight loss: Most people lose 0.5–1kg per week when combining IF with sensible eating
- Improved insulin sensitivity: Helps regulate blood sugar — important for South Africans at risk of type 2 diabetes
- Reduced inflammation: Linked to lower markers of chronic inflammation
- Mental clarity: Many people report improved focus during fasted periods
- Simplified eating: No calorie counting, no meal prep for breakfast
- Cost saving: One less meal per day saves money!
Common IF Mistakes to Avoid
- Breaking the fast with junk food — what you eat still matters. Break your fast with nutritious whole foods.
- Not drinking enough water — dehydration can cause headaches. Aim for 2–3 litres of water daily.
- Overeating in the eating window — IF is not a licence to eat anything. Portion control still applies.
- Starting too aggressively — begin with 12:12 and gradually extend to 16:8 over 2 weeks.
- Quitting in the first week — hunger pangs in week 1 are normal. Your appetite hormones adjust within 1–2 weeks.
Intermittent Fasting for Women
Women may need to approach IF slightly differently. Some research suggests that strict 16:8 fasting daily can affect female hormone levels. Consider:
- Starting with 14:10 (fast 14 hours, eat within 10 hours)
- Having 1–2 "eating normally" days per week
- Avoiding IF in the week before your period if you feel hormonal disruption
Conclusion
Intermittent fasting is one of the most effective and sustainable weight loss strategies available. It's free, flexible, and compatible with South African food culture — whether you're having a braai, eating out, or cooking at home. Start with 16:8, stay consistent for 4 weeks, and let your results speak for themselves.
