What exactly does waist training do and is it safe and effective?

Corsets: Apparently this involves the regular use of corsets, with the purported benefits being eventual weight loss due to decreased appetite, improved posture, and increased "thermal activity." As medical professionals, we cannot condone any alleged treatment that is not proven effective and safe by rigorous controlled medical studies, and I am not aware of any such studies for waist training.

"Waist" of time!: wearing tight corsets does not shape your body when you're not actually wearing the corset. Your body fat percentage will remain the same, and there may be some risk to all of the internal compression. Diet, exercise, and a healthy lifestyle are by far the only way to go to achieving the ideal weight you are shooting for. Good luck.

Dangerous practice: Tight lacing (also called waist training or corset training) can cause shortness of breath, fainting, indigestion. This practice can decrease lung volume (requiring intercostal breathing). Relatively less use of lower lungs can leading to coughing. Some corset styles can push the lower ribs inward. The liver is forced upward & accessory lobes of the liver may form. Stomach volume is reduced & >
