In fact, a lazy skimmer can't really lose weight. It is very unreliable to lose weight with a skimmer and a slimming belt. In order to burn fat, it must be oxidized by oxygen. Applying external forces such as vibration in vitro seems to vibrate fat, but it cannot achieve the effect of aerobic oxidation. In addition, fat itself has no contraction function, does not generate energy, cannot be "crushed" and "vibrates less", and consumes fat molecules in one vibration, which is purely conceptual hype.
