Concerning green tea, Chantre and Lairon26 analyzed its
effect in moderately obese participants, and found a decrease
in bodyweight andwaist circumference. Venables et al27 compared
green tea and placebo ingestion, and showed that the
former could increase fat oxidation by 17% during moderate
intensity exercise (30 minutes of cycling). The calcium of the
plaster body wrap may play a role in explaining the results
of this study. When extracellular calcium level increases,
PTH and 1,25 dihydroxyvitamin D decrease, which leads to
a decrease in intracellular calcium in adipocytes, stimulating
lipolysis and lipogenesis inhibition.15–17,28 Nevertheless,
it is not known if calcium ions have the potential to penetrate
human skin and, if they cross it, does this cause an increase in
extracellular calcium; this aspect needs further investigation.
Magnesium plays an important role once it is picked up by
adipocytes to perform lipolysis, and as fatty acids are mobilized,
its concentration decreases, especially during aerobic
exercise; this is the reason why the application of body wrap
can favor the lipolysis process.14
