Frequently Asked Questions

The NODIET™ Method is TenaZ’s simple, structured eating pattern that helps you eat less, balance your nutrition and follow your body’s natural rhythm — without strict dieting. It rests on three rules:

• Portion Control — how much you eat, measured by your own hand.
• Time Control — when you eat, inside a 12-hour daily eating window.
• Food Control — what you eat: the five TenaZ food groups.

Each day has three steps: eat the NODIET™ way, move more, and take the TenaZ products that support you.

TenaZ products are classified as Category D Complementary Medicines and are manufactured in South Africa by a SAHPRA-licensed, cGMP-certified manufacturer. They have not been evaluated by SAHPRA and are not intended to diagnose, treat, cure or prevent any disease. Always consult your healthcare practitioner before starting.

You book a free online session with a TenaZ wellness coach. We talk through your goals and suggest supportive routines and products tailored to you — with no obligation to buy.

Everyone is different, and individual results vary. TenaZ works best as part of a healthy diet and active routine, used consistently over time.

Please consult your healthcare practitioner first — especially if you are pregnant, breastfeeding, on chronic medication, or have a medical condition.

Most of our range is completely caffeine-free. The only exceptions are Good Morning and No Thank You, which contain a small amount of naturally occurring caffeine from yerba mate, a gentle plant-based source. Any value pack that includes one of these will also contain caffeine, and we clearly label which products these are. If you prefer to avoid caffeine entirely — or are sensitive to it — you can choose from our wide selection of caffeine-free options with complete peace of mind. As always, if you’re unsure, we recommend a quick chat with your healthcare practitioner.

No. We don’t add iodine to any TenaZ product, and our formulas are free from kelp, seaweed and other added iodine sources. We believe in full transparency about what goes into our products, which is why we’re happy to share complete ingredient information on request. If you’re monitoring your iodine intake for a specific reason, we’d simply encourage a quick word with your healthcare practitioner before starting — sound practice with any supplement.

None of our products are made with gluten-containing ingredients — you won’t find wheat, barley, rye, oats or malt in any TenaZ formula. In the interest of full honesty, our products aren’t independently certified gluten-free, and because they’re made in a shared facility we can’t completely rule out trace amounts. For most people this is no concern at all, but if you have coeliac disease or a diagnosed gluten sensitivity, we recommend checking with your healthcare practitioner first so you can choose with confidence.

• To lose weight: eat 1 real meal a day and replace the other 2 with a TenaZ Shake + veggies (or veggies only). To stay at your healthy weight: eat 2 real meals and replace 1. Never eat three real meals a day, and never skip a meal — replace it.
• Break your Fast within half an hour of waking with 1 lean protein, or a TenaZ Shake mixed with 175 ml yoghurt (a Shake in water alone does not count).
• Build each real meal from the five food groups: Breakfast like a King (veggies + 1 protein + 1 fat + 1 carb) · Lunch like a Prince (veggies + 1 protein + 1 fat) · Dinner like a Pauper (veggies + 1 protein).
• Portions by hand: protein = your palm · carb = your fist · fat = your thumb · free veggies and salad unlimited — at least 3 cups per meal, about 9 cups a day.
• Time Control — your 12-hour eating window: carb cut-off 4 hours after waking (fruit counts as a carb — 1 a day for women, 2 for men, first 4 hours only) · fat cut-off 8 hours after waking · last meal 12 hours after waking, and at least 4 hours before bed · free veggies have no cut-off. Wake at 06:00 → Break your Fast by 06:30, carbs until 10:00, fat until 14:00, last meal by 18:00.
• Fluids: bodyweight (kg) ÷ 10 = 250 ml glasses a day, spread through your first 12 hours — water is best (80 kg → 8 glasses). No fluid for half an hour before, during or after a meal.
• Limit sugar, aspartame, wheat and alcohol, eat as little animal fat as possible, and sleep 7–8 hours.

The TenaZ Shake is a nutritional meal supplement that supports a healthy, calorie-managed lifestyle as part of the NODIET™ Method. For adults 18 and older only.

• Serving: 1 nearly full scoop (15 g) in 175 ml cold water or milk. Mix thoroughly and drink within 15 minutes. Up to 100 kg: 1 scoop. Over 100 kg: 1 scoop plus a palm-sized portion of lean protein, or 2 scoops (30 g). Daily maximum 4 scoops (60 g).
• How many meals: to lose weight the Shake replaces 2 meals a day (each with veggies) and you eat 1 real meal; to stay at your healthy weight it replaces 1 meal and you eat 2 real meals. Never replace all three. In your first 4 days you may take the larger serving at each Shake meal if you are hungry.
• Break your Fast: a Shake in water alone does not count as your protein start — have a lean protein, or the Shake mixed with 175 ml yoghurt.
• What to mix it with: water (simplest, fewest kilojoules), milk, yoghurt, pure fruit juice, lite custard or diet ice cream — anything other than water adds kilojoules. First 4 hours of your day: fresh or frozen fruit or cocoa may be added. First 8 hours: full-cream or low-fat mediums, or ½ teaspoon peanut butter. After 8 hours: fat-free mediums only. Last 4 hours: water with a non-aspartame sweetener, a sugar-free flavoured drink powder, coffee powder or cinnamon.
• Add free veggies to every Shake meal — spinach blends well. Still hungry afterwards? Eat more free vegetables.
• No Shake for a meal? Replace that meal with vegetables only — the pattern stays the same.

Your morning and bedtime capsules continue alongside the Shake. Use only as directed.
