Welcome to alli! It's a great Program and I'm sure you'll do well. It's OK to skip the capsule if a meal - most likely breakfast - has 5 grams of fat or less. That shouldn't be for more than one meal a day.
It's very important to have the recommended amount of calories and fat for you level to get the best results with alli. There are two great posts at the top of this message board on why each is so important. Take a look when you have a minute, it's great information.
If you eat more fat than your level allows there are chances of TE's. The more that's consumed the more likely and more severe the TE's will be.
I hope this helps. Please let me know if you need anything else.
