Weight loss claims: When one of the thousands of weight loss products puts out an ad claiming a patient will lose 5 or more pounds in one week, a doctor usually thinks "pounds sterling" or "British pounds", as in money. It's marketing. It's advertising. To lose > 5 pounds a week (it would be fat plus its related water), one can exercise all day and limit intake to 1000 calories a day... but it is not healthy to do.
