Fgs what a stupid article! The problem isn't that people don't know that all those things would make you lose weight. The problem is that people can't stick to doing them.
As for the ridiculousness of starting the article by saying people fail at diets because they're too harsh or complicated, and then promptly giving a massively long list of things you should do, including daily weighing, calorie counting and lots of specific monitoring of packaging, specific numbers of nuts, etc...
Words fail me really.
