And there are more people coming here asking " if I fast for 20 days how much will I lose' then people coming here to cure heart disease, cancer, a cold, emotional issues etc, and that is fact, if you look around.
If you look at the numbers of people "reading" a post, it is far higher than the number of people actually posting in the forum. That being said, it's rather challenging to say that more people come here for weight loss than for any other reason. It may be true, but there's no data to back it up.
