Fat Burners Explained – What Works and What Doesn’t
Walk into any supplement store or search online and you’ll see endless fat burners promising rapid weight loss. But the big question is: do they actually work? The truth is, some ingredients are backed by science, while others are marketing hype. Here’s how to separate fact from fiction — and how to use fat burners alongside a solid diet and training plan.
What Fat Burners Can (and Can’t) Do
No fat burner will replace a calorie deficit and regular training. However, the right ingredients can give you an edge by boosting metabolism, increasing energy, supporting appetite control, and enhancing workout output. Think of them as a support tool, not a magic bullet. If you’re ready to browse options, shop our full Fat Burners range.
Ingredients That Work
- Caffeine: Increases energy expenditure and enhances training performance. Great for morning use or before workouts.
- Green Tea Extract (EGCG): Supports fat oxidation and can help nudge calorie burn upward.
- L-Carnitine: Transports fatty acids into mitochondria to be used for energy; pairs well with low-intensity cardio.
- Cayenne/ Capsaicin: Raises thermogenesis (heat production), potentially increasing daily calorie burn.
- Chromium: Works with insulin to help metabolise carbs and fats and may stabilise blood sugar, which can reduce cravings.
- Kelp (Iodine): Provides iodine to support healthy thyroid function — a key regulator of metabolic rate — and alginate fibre that may help reduce fat absorption.
Branded (Trademarked) Ingredients Worth Knowing
- InnoSlim®: Designed to reduce glucose absorption while enhancing fat burning and muscle glucose uptake — useful during cutting phases.
- Cardamoxine™: Targets thermogenesis in brown adipose tissue, encouraging conversion of “white” fat into more metabolically active “brown” fat.
- ForsLean® (Coleus forskohlii extract): Supports cAMP signalling, a pathway associated with increased fat mobilisation and metabolic rate.
What to Watch Out For
“Proprietary blends” aren’t automatically bad, but they can hide under-dosey formulas. Prioritise products that either disclose key actives and/or have a strong reputation for using effective amounts. Trendy ingredients with little research are less reliable than time-tested compounds.
Side Effects & Tolerance
High-stim products can cause jitters or sleep issues. Start with a half serving to assess tolerance, avoid stimulants late in the day, and stay hydrated.
Smart Use Tips (That Actually Move the Needle)
- Check Your Tolerance: Begin with a lower dose and build up only if needed.
- Prioritise Protein: Helps preserve lean muscle and keeps you fuller for longer. Great sources: lean meats, fish, eggs, Greek yogurt — or a quality protein powder.
- Eat Mostly Whole Foods: Base your diet on fruits, veg, whole grains, and healthy fats (olive oil, nuts, avocado). Limit ultra-processed foods and added sugars.
- Stay Hydrated: Water supports metabolism and appetite control — especially important with thermogenics.
- Control Portions: Even “clean” foods can stall fat loss if you overshoot calories. Eat slowly and stop around ~80% full.
- Time It Right: Most stim-based burners work best in the morning or 30–45 minutes pre-workout.

The Role of Lifestyle
Even the best formula won’t outwork a poor diet or inconsistent routine. Nail your steps, sleep, protein, and training — then use a fat burner to add a 5–10% boost.
Conclusion
Fat burners can be a useful addition to your plan — especially those with proven ingredients like caffeine, green tea, carnitine, capsaicin, chromium, and kelp. Consider trademarked actives such as InnoSlim®, Cardamoxine™, and ForsLean® for extra firepower. Start low, monitor how you feel, and remember: consistency beats shortcuts.
