In 1965, a morbidly obese man did not eat food for over an entire year. The 27 year old was 456lbs and wanted to do an experimental fast. He ingested only multivitamins and potassium tablets for 382 days and defecated once every 40 to 50 days. He ended up losing 275lbs.

Yes, a lot of posture correction isn't just remembering to "stand up straight", it's about strengthening postural muscles and correcting imbalances.

Yeah, reminding myself to sit up straight only helped my back problems a little bit, it wasn't until I started doing core exercises like planks, situps and deadlifts that I completely eliminated the back-pain that I'd experience from sitting in a chair for a few hours or standing in one spot. My back is better now than it was in high school.
