Alli warning labl on ‘treatment’ side effects.

You may have heard about the new wonder drug, the over the counter weight loss pill Alli (actually its just a lower dosage of a long time Rx drug).  Anyway, the pill is supposed to keep 25% of the fat you eat from being digested (doesn’t do anything to stop calories from carbs and protein from being absorbed - too bad for us carb addicts..)  Anyway, the drug sounds wonderful until you read (and they aren’t being too subtle about this although the angry aussie does translate to even less subtle warnings at Why Am I Angry, alli: Miracle diet pill with teeny-tiny side effect. 

“How do you prevent these side effects? Simple. Just limit yourself to no more than 15 grams of fat per meal. Yes, you heard that right — in order to get the benefit of alli, you’re supposed to eat a low-fat diet. Correct me if I’m missing something, but if you’re already eating a low-fat diet, why would you need alli?

Putting it a different way, if alli prevents you from absorbing a quarter of the fat you eat, that means that for a meal with 15 grams of fat in it (at nine calories per gram), it’d be saving you approximately 36 calories. Not to get all philosophical, but if someone were to ask me how many calories it would take to get me to risk shitting myself in public, it’d be a hell of a lot more than 36.” from Salon Broadsheet
