Hi Sam,
Orlistat, also known as Alli (an over-the-counter medication), can have certain unwanted gastrointestinal side-effects. The website MyAlli.com provides the following advice regarding the amount of fat consumed in a meal:
alli blocks 25% of the fat you eat from being absorbed, and the fat that isn't absorbed is harmlessly passed through your bowels. As a result, you may experience some bowel changes during the first few weeks of use. These alli side effects are most likely to occur after taking an alli capsule and eating a meal containing more than 15 grams of fat. Staying below your fat threshold lowers the chance of these alli side effects. If you do experience a alli side effects, it may be because you've gone beyond your target. It's helpful to think of these effects as reminders from your body that you need to stick to lower-fat foods.
Tips on eating are also provided on their website. You may want to check it out. Hopefully you will find some helpful information.
Good luck on your weight loss journey.
