Men's slimming clothes are essentially corsets, and they can't lose weight. Although people who wear this kind of underwear will see a little improvement in their figure, it is actually the tight underwear that squeezes the fat in the waist and abdomen, or that squeezes the fat to other parts. In essence, the fat has not decreased, so taking off the slimming clothes will suddenly change back to its original state. Tight underwear can also lead to poor blood circulation in the waist and abdomen, causing various diseases. Especially, never sleep in tight underwear at night, because the human body needs smooth blood circulation for tissue repair at night, so sleeping naked at night is the most scientific.
