If ECAS work by raising body temp. then dont fat burners work the same?

[jbk]

The science behind ECAs is that it raises body temp therefore you burn fat but my experience with fat burners like LIPO 6 give me a raise in body tempurature for sure. with all the caffeine and other ingridients they put in does it not do the same and have the same science behind it?

why would ECA's be so much better then other fat burners without ephedrine?

and has alone had experience with the fat burner Cellucor® D4 THERMAL SHOCK? heard some good things bout it and has a 9.4 rating on bodybuilding.com ! never seen sucha rating on a fat burner

Ephedrine is a sympathomimetic drug that increases metabolism, etc, a side effect of that being a slightly raised the core body temp. Ephedrine effects the beta receptors in the body increasing and mimicing norepinephrine. Caffeine, yohimbine, synephrine (which is the closest) won't do that in any quantitity.

Most fatburners have stuff in them that also increase adrenaline levels to help burn the fat and slow down digestion time to keep full for longer so you eat so much food
