How Do Fat Burning Supplements Work?

Weight (fat) loss is a goal for many people entering the gym. One need look no further than the millions of fat burning supplements that are sold each year, or the fact that nearly ⅔ of the adult population is overweight or obese to see that all things weight loss are in high demand.[2]

And when you consider that roughly 34% of individuals trying to lose weight fast purchase a fat burner, it becomes painfully obvious that excess adipose tissue (a.k.a. fat) is public enemy #1.

Despite the enormous popularity of fat burners, most consumers have no clue how they work.

Today, we review the fundamentals of fat burning supplements -- what they do, and how they work, so the next time your in need of a powerful thermogenic fat burner, you know what you’re getting.


Fat burning at a cellular level is an incredibly complex process, one that requires an article all its own. For the sake of brevity, we’ll hit the “highlights” of how they work.

  • Increase lipolysis

    Lipolysis is the process by which fatty acids stored in fat cells are “liberated” into the bloodstream where they can be shuttled into cells and burned for energy. Ingredients that have been noted to enhance lipolysis include caffeine, citrus aurantium, and rauwolscine (alpha-yohimbine).

  • Enhance fat oxidation

    When people say “burn fat for fuel”, they are referring to beta-oxidation -- the actually “burning” of fatty acids in mitochondria for energy. Supplements to enhance fat oxidation include fucoxanthin and caffeine.

  • Reduce appetite

    Since weight loss is primarily a function of calories in vs calories out, anything that helps reduce the amount of calories you ingest by definition enhances fat loss. Stimulants (caffeine, yohimbine, etc.) are far and away the common supplements used to kill appetite and help you stop feeling the urge to snack.

  • Boost thermogenesis

    Thermogenesis the process by which an organism generates heat. In order to generate this heat, your body has to burn calories -- accelerating this process is the holy grail of fat burning supplements. And, Killer Labz includes two of the most powerful thermogenic metabolism boosters in 3,5-Diiodo-L-Thyronine and Paradoxine.
