Types of Fat Burners & Weight Loss Supplements

• Stimulant-Based Fat Burners – Thermogenic supplements containing caffeine and other stimulants to increase metabolic rate, boost energy, suppress appetite, and enhance fat oxidation. Ideal for those who tolerate stimulants well and want maximum fat burning support.
• Stimulant-Free Fat Burners – Caffeine-free thermogenic and fat loss formulas for those sensitive to stimulants, training in the evening, or cycling off caffeine. Effective fat loss support without the jitters or sleep disruption.
• Weight Loss Shakes & Meal Replacements – High-protein, calorie-controlled shakes designed to replace meals and support a calorie deficit. Convenient, filling, and nutritionally balanced to support sustainable weight loss.
• Appetite Suppressants – Supplements containing glucomannan, 5-HTP, and other compounds shown to reduce hunger and support calorie control.
• L-Carnitine – Supports fat metabolism by transporting fatty acids into the mitochondria to be burned as energy. Available in liquid and capsule form.
• CLA (Conjugated Linoleic Acid) – A naturally occurring fatty acid shown to support body composition by reducing fat mass and preserving lean muscle.
• Thyroid & Metabolism Support – Supplements containing iodine, selenium, and other nutrients that support healthy thyroid function and metabolic rate.

Key Fat Burning Ingredients to Look For

• Caffeine – Increases metabolic rate, enhances fat oxidation, and boosts energy for more effective training sessions
• Green Tea Extract (EGCG) – A powerful antioxidant that supports fat oxidation and thermogenesis
• Cayenne Pepper / Capsaicin – Raises core body temperature to increase calorie burn throughout the day
• Glucomannan – A soluble fibre that expands in the stomach to promote feelings of fullness and reduce calorie intake
• Synephrine – A stimulant compound that supports metabolic rate and fat breakdown

How to Get the Most from Fat Burners

• Always use alongside a calorie-controlled diet — fat burners support fat loss, they don't replace good nutrition
• Combine with regular exercise for maximum results
• Start with the lowest recommended dose to assess tolerance, especially with stimulant-based products
• Avoid stimulant fat burners within 4–6 hours of bedtime to protect sleep quality
