My uncle is on a liquid diet. I believe it is Slimfast that he is using.. He claimed that the lost about 10 pounds in three days.. It's hard to believe because he just sits in his chair all day.
Is a liquid diet a healthy way to lose weight? Any risks involved? Because if he is telling the truth about losing 10 pounds in 3 days.. That is about 20 pounds a week or about 100 pounds in 5 weeks..
