there are key words (or phrases) that the "industry" uses that "we" fall for. Words such as "as much as", "up to", "as little as". I translate that to "no more than", again "no more than", "at least".
Example "You can lose up to 30 pounds in as little as 30 days." For one this doesn't say you will... but you CAN lose no more than 30 pounds in at least 30 days." In other words if you lose 1 pound, that is "up to" 30 pounds so it is true.
How about my own line.... During my weight loss period, I'd have cheat days, like everyone else. My weakness is a Butterfinger. So could say (and it's true) "I lost 40 pounds while eating Butterfingers!" That is totally true but very misleading.
The one thing that many of us ignore is the one that is in our face "RESULTS WILL VARY." Just b/c Joe Schmoe did it, that doesn't mean that you'll get the same results, in fact you know that they picked someone at the end of the bell curve to put in their ad.
