Hi, I am a dietitian and have several clients that take Xenical.
Xenical works by binding with Gastric and Pancreatic Lipase; enzymes
that help you absorb fat. The goal is try try and eat 30% calories
from fat at a meal that you have taken Xenical with. I really
recommend sticking with about 30% calories from fat. Believe me, you
have probably experience the side effects of eating a meal with a
greater percentage of fat than 30%-- NOT FUN!!! But, you don't want
to eat a diet that is TOO low in fat, because you really won't get any
benefit from taking the Xenical. It's worth doing your homework to
make sure you are eating about 25-30% of your calories from fat!
Generally, Xenical will prevent you from absorbing about 30% of the
fat that you consume at a meal that Xenical is taken with. So, what
you can do, is look at how many fat grams you have eaten at each meal
where you took Xenical:
With EACH meal, do the following to figure out how many calories you
are avoiding::
1. Look at the nutrition labels of the foods you ate at that meal, and
look at the TOTAL fat grams Just look at Fat or Total Fat on the
nutrition label, don't add the Saturated, Unsaturated, or Trans fats
to this number, as they are already included in the total fat grams.
ADD up your total fat consumption for EACH meal, but don't add the
totals up for the day, keep them separated by meal, and ONLY look at
meals that you took Xenical WITH.
2. Now, multiply the total fat grams eaten at each meal by 0.3 - This
will give you the number of fat grams that you DID NOT absorb, because
of the Xenical. (because Xenical typically prevents you from
absorbing about 30% of the fat you ate at the meal)
3. Take the number of fat grams that you got in step 2, (fat grams
that you didn't absorb, and multiply this number by 9. There are 9
calories in each gram of fat. This will show you how many calories
you didn't absorb from the meal.
4. Figure out how many calories were blocked for the entire day.
5. Remember that you will need to create a 3500 calorie deficit to
lose 1 pound.
By doing this, you can see that Xenical has a pretty SMALL impact on
the amount of weight that you lose. IF I ate 2000 calories a day, and
30% of my calories were from fat, and I only ate 3 meals, with that
fat divided evenly at those 3 meals, taking Xenical with each meal, I
would block about 20g of fat per day, which is equal to about 180
calories each day. So, it would take me about 2.5 weeks or so to
lose one pound. (and this is assuming that 2000 kcals is the amount
necessary to maintain my wt.)
HOPE this makes sense and HELPS you out!!!! :-)
