“How fast will I see results?” is the first thing most people want to know before starting the HCG diet. It’s a fair question — and the answer is one of the program’s biggest advantages: results are visible early, measurable daily, and significantly faster than almost any other diet approach.
This NZ timeline breaks down what to expect day by day and week by week on HC-SLIM, what’s actually happening in your body at each stage, and how to interpret the scale so you don’t panic during normal fluctuations.
Days 1–2: Loading Phase
What you do: Start taking HC-SLIM drops (8 drops, 3 times daily) and eat freely — generous portions of calorie-dense food including fats, dairy, and carbohydrates.
What the scale does: Goes up. This is expected and intentional. You’re building glycogen and fat reserves that your body will draw on during the first week of Phase 2. Don’t be alarmed by 1–3kg of scale increase on loading days.
What’s happening: The HC-SLIM drops begin building in your system. Proper loading reduces hunger in Days 3–7 significantly — this is why skipping loading days is one of the most common mistakes.
Days 3–7: First Week of Phase 2
What you do: Begin the 500-calorie food protocol. Two meals per day (lunch and dinner), each with 100g lean protein, one approved vegetable, and one fruit portion.
What the scale does: Drops quickly. Most NZ HC-SLIM customers lose 2–4kg in the first week. The initial drop includes some water weight from glycogen depletion, but genuine fat loss begins from Day 3.
What you feel: Days 3–5 are typically the hardest. Mild hunger, possible headache, and fatigue as the body transitions to fat-burning mode. This passes. By Day 6–7, most people report hunger has decreased noticeably and energy begins returning.
Daily loss rate: Typically 0.3–0.7kg per day in week one. Higher initial rates are common in the first few days as excess water clears.
Week 2: Steady Fat Loss
What happens: The fast initial drop settles into consistent daily fat loss. The 0.3–0.5kg/day rate is now almost entirely true fat, not water weight.
What the scale does: Moves consistently downward, with occasional one-day plateaus or small upticks that are normal. A day with no loss or a tiny gain doesn’t mean the program isn’t working — it usually reflects water retention from the previous day’s food choices, higher sodium, hormonal fluctuation (for women), or simply normal metabolic variance.
What you feel: Energy has generally stabilised. Most customers report being in a rhythm by Week 2 — the food protocol is established, the drops schedule is automatic, and the daily scale results are motivating. Hunger is minimal for most people in this phase.
Cumulative results by end of Week 2: Most NZ customers have lost 4–7kg. Men often towards the higher end; women slightly lower depending on cycle timing.
Week 3 (26-Day Program) or Weeks 3–5 (40-Day Program)
What happens: Continued steady fat loss with the occasional plateau day or brief stall. If you’re on the 40-day program, around Week 3–4 you may hit what’s known as an “apple day” moment — a day or two where the scale doesn’t move. This is a normal metabolic adjustment, not a failure.
The plateau fix: If the scale sticks for two or more consecutive days, an “apple day” can help: eat only 5–6 apples throughout the day (and nothing else except water). The next morning, the scale typically drops 0.5–1kg and progress resumes.
What you feel: Body composition is visibly changing. Clothing fits differently. Belt notches change. Many customers notice compliments from others in this phase, even if they themselves have become accustomed to seeing the change daily in the mirror.
Cumulative results by Week 3: 5–9kg on the 26-day program; 7–10kg on the 40-day at this midpoint.
Final Days of Phase 2
What happens: The final days of the program often see a slight reduction in daily loss rate as the body approaches its limits for this round. This is normal and expected.
On the final day of drops: Continue the food protocol but stop taking HC-SLIM drops. The drops stay in your system for 72 hours, so continue the 500-calorie protocol for two days after your last drops before transitioning to Phase 3.
Total Results: 26-Day vs 40-Day Programs
26-Day HC-SLIM Program (NZ averages):
Women: 4–8kg | Men: 6–10kg | Higher starting weight: 8–12kg
40-Day HC-SLIM Program (NZ averages):
Women: 8–12kg | Men: 10–16kg | Higher starting weight: 12–20kg
Not sure which programme suits your goals? Read our 26-Day vs 40-Day HCG Diet NZ guide. These are averages for customers who follow the protocol correctly. Individual results vary — some people lose more, some less, depending on starting weight, age, hormonal status, adherence, sleep, stress, and other factors.
What Affects Your Results
Starting weight: Heavier people typically lose more weight per round, particularly in the first week. Someone starting at 120kg will lose more than someone starting at 75kg on the same program length.
Age: Metabolism slows with age, and hormonal changes (particularly in women over 40 during perimenopause or menopause) can affect results. Results are still very achievable — they may just come slightly slower. Our women over 40 guide covers this in detail.
Gender: Men consistently lose more weight than women on the same program, due to higher testosterone levels and greater muscle mass. See our HCG diet for men NZ guide.
Adherence: The most significant variable. Following the food protocol exactly — no oils, no unlisted foods, correct portion sizes — makes a substantial difference to results. Even small deviations add up over 26–40 days.
Sleep and stress: Poor sleep and high cortisol from stress both slow fat loss. These are harder to control, but worth being aware of if your results are slower than expected.
After the Program: Phase 3 and Long-Term Maintenance
Results don’t stop at the end of Phase 2. Phase 3 — the 21-day maintenance phase — is where your new weight stabilises as your body’s new set point. This is what makes the HCG diet different from conventional crash diets: the metabolic reset in Phase 3 means results can last for years, not weeks.

Frequently Asked Questions
What if I don’t lose as much as the averages?
Don’t compare your results to averages in the first two weeks — some bodies take longer to shift into fat-burning mode. If you’re consistently losing even 200g per day, that’s over 5kg in 26 days. Slower but steady results are still excellent outcomes.
When will I notice a visible difference?
Most customers notice visible changes in their clothing fit and mirror reflection by Day 10–14. Partners and friends often notice before the person themselves does, because familiarity with your own reflection adjusts more slowly than the actual change.
Can I speed up my results?
Not by taking more drops or eating less than 500 calories — both strategies backfire. The program is calibrated. The best way to maximise results is strict adherence to the food list, adequate water intake, good sleep, and minimal stress.
Is the first round always the best?
Not necessarily. Some customers find their second round produces results comparable to or better than the first, particularly once they know the protocol well and can fine-tune their food choices. Multiple rounds with proper maintenance breaks are a legitimate strategy for larger goals.
