Has anyone here tried Penn Gillette's potato diet? There are a number of potato diet videos on YouTube, claiming that those who have tried it have lost up to 100 pounds in three or four months. I presently weigh 335 pounds and have mobility issues dues to my age (75) and advanced arthritis. I could probably get around a lot easier if I could shed 100 pounds by next December. Any thoughts or recommendations?
