Weight Loss Supplement FAQs
What is the best supplement for weight loss?
There’s no single supplement that guarantees weight loss, but certain products may support your weight management goals when used alongside a balanced diet and regular exercise. Popular supplement types in this space include thermogenics, fat metabolisers, appetite support formulas, and caffeine-based pre-workouts. These may help by supporting energy levels, increasing focus during training, and encouraging a healthy metabolism.
The best supplement for you depends on your lifestyle, training style, and how your body responds to different ingredients. Some people find support with stimulant-based formulas, while others prefer stimulant-free options that can be taken at any time of day. It's important to remember that supplements are designed to complement, not replace, the foundations of good nutrition and movement.
If you're unsure where to start, speak with a health professional or connect with our team in-store or online for personalised support.
How do weight loss supplements like fat burners and thermogenics work?
Fat burners and thermogenics are designed to support your weight management efforts by helping to increase energy levels, enhance focus, and promote thermogenesis, a natural process where your body produces heat and burns energy. These supplements typically contain ingredients like caffeine, green tea extract, carnitine, or capsicum, which may support mental alertness and performance during workouts.
Thermogenics may assist by encouraging the body to burn more calories during exercise or daily activity. Some formulas also include ingredients that help reduce fatigue or manage appetite, making it easier to stay consistent with your training and nutrition plan.
It’s important to note that these supplements don’t cause fat loss on their own. They’re intended to complement a well-rounded approach that includes a nutritious diet, adequate sleep, hydration, and regular movement.
If you're sensitive to stimulants or training later in the day, stimulant-free options are available that offer a different type of support without affecting sleep.
Are protein shakes good for weight loss?
Absolutely! Protein shakes for weight loss, such as keto protein or low-calorie protein, help you maintain lean muscle while supporting a calorie deficit. If you’re looking for plant-based options, check out our Top 10 Vegan Protein Powders for sustainable solutions.
What are the different weight loss supplements?
There are several types of supplements that may support weight management goals, each working in different ways when combined with a balanced diet and exercise routine.
Common categories include:
Thermogenics and fat burners, which are typically stimulant-based and may help promote energy, focus and thermogenesis — the body’s natural heat production that can increase calorie expenditure during physical activity.
Appetite support formulas, which may help reduce snacking or manage cravings with ingredients like fibre, chromium, or mood-balancing herbs.
Carnitine-based supplements, such as L-Carnitine or Acetyl L-Carnitine, which support fat metabolism by assisting in the transport of fatty acids for energy production.
Meal replacement shakes or low-carb protein powders, which offer a convenient, portion-controlled way to meet protein needs and stay fuller for longer — particularly useful when reducing overall calorie intake.
Stimulant-free options are also available for those avoiding caffeine, offering alternative ways to support metabolism, energy, or focus.
What is the role of L-carnitine and acetyl L-carnitine in weight loss?
L-carnitine and acetyl L-carnitine are ingredients often included in weight loss supplements for their role in energy metabolism. Research suggests they may assist in fat transport within cells, potentially supporting energy production during exercise (National Institutes of Health, 2023). To maximise benefits, they can be paired with a balanced diet, exercise routine, and products like fat burners or thermogenic protein powders.
What are the best snacks for weight loss?
The best snacks for weight support depend on your individual needs and preferences, as each person is different. For convenient, high-protein options, try protein bars, protein snacks, or protein snacks and drinks. Our Top 10 Protein Bars are excellent for satisfying your appetite and supporting your calorie deficit, making them a great addition to your weight loss journey.
If you need additional guidance with weight loss or nutrition, consider booking a session with a registered dietitian to create a personalised plan that works for you.
Do I need to take a weight loss supplement before working out?
You don’t need to take a weight loss supplement before working out but some people choose to use certain products pre-training to support energy, focus or motivation during exercise.
Many weight management supplements, such as thermogenics or caffeine-based formulas, are designed to be taken before physical activity to help promote alertness and performance. This may help you train more effectively, particularly when exercising in a calorie deficit or during early morning sessions.
Can protein help support my weight loss?
Yes, increasing your protein intake can support your weight loss goals, especially when combined with a calorie-controlled diet and regular exercise. Protein plays a key role in helping you feel fuller for longer, reducing the likelihood of overeating or snacking between meals.
It also assists with preserving lean muscle mass during periods of reduced calorie intake, which is important for maintaining a healthy metabolism and supporting long-term results. Using a high-quality protein supplement can be a convenient way to meet your daily protein needs, particularly if you're on the go or find it difficult to get enough through food alone.
Will pre workouts help with my weight loss?
Pre-workouts won’t cause weight loss on their own, but they may support your training performance, which can play an important role in a weight management plan. These supplements are typically designed to increase energy, enhance focus, and help you get more out of each workout.
Some pre-workouts contain ingredients like caffeine, beta-alanine or carnitine, which may support exercise intensity, endurance or fat metabolism. By helping you train harder or for longer, pre-workouts can indirectly support your fitness and body composition goals.
However, they're not essential. Weight loss ultimately comes down to creating a calorie deficit through a combination of consistent exercise, nutrition, and recovery. Pre-workouts are simply a tool that may help you stay motivated and energised, particularly when training while dieting or during low-energy phases.
Are there any side effects to weight loss supplements?
Some people may experience side effects when using weight loss supplements, depending on the product type, ingredients, and individual tolerance. These side effects are usually mild and can include things like increased heart rate, restlessness, digestive discomfort, or trouble sleeping, especially with stimulant-based formulas that contain caffeine or similar ingredients.
Not everyone will experience side effects, but it’s important to follow the recommended serving size and avoid combining multiple stimulant products. Those sensitive to caffeine may prefer stimulant-free options that are gentler on the nervous system.
As with any supplement, it's a good idea to speak with a healthcare professional before starting something new, particularly if you have existing health conditions or are taking medication.
Can I rely on just weight loss supplements?
No. Weight loss supplements are not a substitute for a healthy lifestyle. While certain supplements may support your energy, focus, metabolism or appetite control, they are not designed to work on their own.
Sustainable weight loss comes from a combination of balanced nutrition, regular physical activity, quality sleep and stress management. Supplements can play a supportive role by helping you stay consistent or filling in gaps, but relying on them alone is unlikely to deliver meaningful or lasting results.
Think of supplements as one part of a broader strategy. When used correctly, alongside healthy habits, they may assist you in staying motivated, managing your routine, or getting more out of your workouts.
If you’re unsure where to start or how to build a plan that suits your goals, a conversation with a qualified health professional or one of our knowledgeable team members can help point you in the right direction.
How to choose the right weight loss supplement?
Choosing the right weight loss supplement depends on your individual goals, lifestyle, and how your body responds to certain ingredients. Start by identifying what kind of support you’re looking for, whether it’s increased energy for workouts, appetite management, help with recovery, or simply staying on track when motivation dips.
If you train in the morning or need a mental and physical boost, a stimulant-based thermogenic may suit you. If you’re sensitive to caffeine or train later in the day, stimulant-free options are available that support metabolism and energy without affecting sleep. L-Carnitine formulas may assist with fat metabolism during training, while high-protein or low-carb shakes can support satiety and lean muscle maintenance.
It’s also important to check the label for ingredients, dosage, and any usage directions and to avoid combining multiple stimulant-based products.
