Fat burners shouldn't work...

[NYhomeboy]

I'm obviously being facetious which the title, but hear me out as I've been curious about this for quite a while. How does a "fat burner" cause one to create a larger caloric deficit unless it a) raises your body temperature, b) causes shakes/extra curricular movement, or c) interferes with absorption? Any fat burner which claims to cause an increase in caloric deficit without doing any of the above would contradict the laws of thermodynamics, no?

I'm just curious... For example, Venom kicked ass for fat loss, but I checked my body temperature, which remained fairly constant, and it did not cause any shakes. EC and albuterol both allowed me to remain energized while cutting, but neither of them caused the above sides as well. Obviously there are many fat burners that work that do not have the above side effects, but what are there methods of working? Causing the body to simply release oxidized fat into the bloodstream would not in itself allow one to burn more fat.

A response from anyone which more scientific knowledge than I have would be much appreciated!

One of the main limiting factors is the ability to oxidize the FFA's that are released into the bloodstream. Thyroid hormones, sesamin, TTA, and OEA help to increase the rate of oxidization of the FFA. Unless the body can "burn" the FFA in the bloodstream, the FFA will only be reabsorbed later.

Right, but wouldn't increasing the oxidation of fat also have a thermogenic effect? I guess another method besides a thermogenic increase would be increasing the rate of FFA usage for energy versus other sources, making it more of a repartitioning agent -- but I haven't experienced much more muscle/glycogen retention with these products.

If anything PPARalpha agonists are known for their muscle flattening and strength side effects. Usually, which the exception of T3, T4, etc., PPARalpha agonists do not really increase the core temp, but thermos/stims increase the HR which increases the body temp.
