Top Rated Diet Pills of 2016
BACKGROUND Start the Diet Now Advertisement

There are many diet pills on the market claiming that their "secret," "proven," "patent-pending" formula is the weight loss answer you've been looking for. But few come with an FDA approval nor a prescription-strength formula like Xenical (also known as Orlistat).

Xenical is prescribed to obese individuals only by their physician and after determining their body mass index (BMI) is 30 or higher (27 if you have other risks like blood pressure or diabetes). Xenical is responsible for helping many overweight individuals finally find success and maintain. Xenical is usually not considered a first choice. Your physician will want to know if you've already tried diets, exercise and other weight loss means, but yet to find success.

So how exactly does Xenical work so succesfully? Xenical works directly in your digestive system and is responsible for keeping 1/3 of the fat you ingest from being absorbed. This is why Xenical calls for a serious reduction in the amount of fat you consume.

Do You Know the Best Diet Pills of 2016?

  • Specially formulated for those that are obese
  • Keeps some of the fat you consume from being absorbed by your body
  • Prescription strength formula
  • Low-fat diet is a must
  • Side effects include oily spotting from the rectum, urinary tract infection, tooth or gum disorders and gall stones among others
  • Must have a prescription
  • Only obese individuals can take this pill

Orlistat is the main ingredient in Xencial. A complete list of ingredients for Xenical is not available. Because this is a prescription only product, your doctor would be able to share the ingredients with you before prescribing.


Your doctor would be able to explain dosage and how many tablets to take daily. This information is not available without having a prescription.


While taking Xenical, you'll follow a low-fat diet (no more than 30% of your calories) that is identical to the diet outlined by the American Heart Association.

Xenical is a 120 mg capsule and is only available by prescription. It is to be taken with meals that contain fat, no more than three times daily. Xenical also encourages taking a multi-vitamin each day.


Xenical is not for everyone. Since it's made for prescription, it's given to those who are most in need.

I have been taking Xenical for 4 days now. I have not had any bouts of "oily" anything! I take it this means I am not consuming too much fat. No weight loss, but, it's only been 4 days! Anyone else like me, whereby you did not experience any "oily" stuff, but, did lose weight? What day did you notice the firs weight loss? Thanks!

I have been using xenical for quite sometime now. My BMI is lower than 27... but I do binge often. On weekends, XENICAL takes care of my fat intake. I am not a gym person, so xenical helps me to maintain my weight. But i WANT TO LOSE MORE.

Ihave just started taking xenical 120mg 3 times a day and I felt so embarrassed breaking wind now I where a pad but I am finding it difficult to work full time and travel plus taking this tablet

This product does work! It is not a magic pill and You have to be willing to change your eating habits! If you follow the directions and limit your fat intake you will be fine.

i have been on these tablets for 2 weeks, i lost 8lbs in my first week and 6lbs in my second. It is true what they say you really do have to watch your fat intake but it is well worth it to see the pounds come off!!
