1. Optifast VLCD shake

The Optifast VLCD Shake is a meal replacement designed for the Intensive Level program, which limits participants to 800 calories per day while ensuring they receive key nutrients.

The shake contains ingredients like skimmed milk powder, milk proteins (calcium caseinate and sodium caseinate), maltodextrin, and vegetable oils, along with a blend of vitamins and minerals. Available in vanilla, chocolate, strawberry, and coffee flavours, it offers both variety and balanced nutrition.

Clinical studies show that participants on the intensive level typically lose 1.0 to 2.5 kg (about 2.2 to 5.5 pounds) per week, with an average total weight loss of around 20 kg (44 pounds) over 12 to 16 weeks. The program also induces ketosis, which can naturally reduce appetite, making it easier to stick to the plan.

Important health guidelines

Before starting the program, keep these points in mind:

• Medical supervision is strongly advised, especially for individuals with a BMI over 30 or those with a BMI between 27 and 30 who have weight-related health concerns.
• The intensive level is not suitable for individuals under 18, over 65, pregnant or nursing women, or those with certain medical conditions.
• Regular check-ups are crucial, as significant weight loss can impact how some medications work.

Pricing and availability

The shakes are competitively priced. A 12-pack of coffee or strawberry flavour costs A$40.57 (down from A$57.95), while an 18-pack of Chocolate is priced at A$52.47 (reduced from A$74.95).

For optimal results, pair the shakes with plenty of water and low-starch vegetables as part of a structured plan.

How to select a weight loss shake

Choosing the right weight loss shake means looking closely at its nutritional details and ensuring it meets safety standards. After reviewing Australia's top options, use these key factors to find the one that fits your lifestyle.

Key nutritional components

A good weight loss shake starts with its nutritional breakdown. Here's what to look for:

Besides the macronutrients, pay attention to ingredient transparency and safety certifications.

What to look for in quality

Check for third-party certifications to ensure the product is safe and reliable:

• NSF Certified for Sport
• Informed Sport
• Good Manufacturing Practice (GMP)

These certifications show the product has passed strict safety and quality tests.

The importance of protein sources

Not all proteins are created equal. Whey protein is known for helping improve body composition, while plant-based proteins like pea protein add extra fibre benefits [4]. Research suggests that diets with over 25% of total calories from protein can help maintain lean body mass, especially for those over 50.

How to read labels

When reviewing product labels, focus on these areas:

• Ingredient quality: Look for whole-food ingredients listed first and steer clear of artificial additives.
• Dietary needs: Make sure the shake aligns with any dietary restrictions, such as vegan, allergen-free, lactose-free, or gluten-free options.
• Cost per serving: Compare the price per serving to ensure it fits your budget. High-quality ingredients often deliver better results.

Tips for using weight loss shakes

For the best experience, try these practical tips:

• Mix shakes with milk alternatives for added nutrients.
• Add fruits or vegetables to boost fibre content.
• Time your shake around workouts for optimal energy.
• Start with one shake a day to see how your body reacts.

Studies show that adding protein shakes to a balanced diet can lead to 3–4 more pounds of weight loss compared to just cutting calories.

Staying safe

Safety is just as important as nutrition. Since the FDA doesn’t evaluate supplements for safety or effectiveness before they hit the market, stick to shakes with third-party testing. If you have specific health concerns or dietary restrictions, consult a registered dietitian for tailored advice.

When choosing a shake, keep these important factors in mind:

• Nutritional balance: Aim for shakes with about 20–30 grams of protein and 2–3 grams of fibre per serving. Protein-rich diets can help maintain muscle while losing fat.
• Low sugar: Opt for shakes with little to no added sugar. For instance, some formulas contain as low as 0.9 grams of sugar per serving.
• Health benefits: Research shows that shakes high in protein and fibre can play a key role in weight management. Adding just 10 grams of fibre daily may lower the risk of diabetes by 25%.

Pair your shake with a healthy diet, regular exercise, and tools like Vively’s CGM (Continuous Glucose Monitor) for the best results. Tracking your blood sugar in real time can help you understand how different foods affect your metabolism, making it easier to optimise your weight loss journey.
