Welcome to alli! It's a great Program and I'm sure you'll do well.
This issue comes up often, and it's solved by using more regular or LF items rather than FF. We've all been so brainwashed about FF that sometimes it's tricky to reverse that notion. However, the alli diet is 30% total calories from fat - same as the diet of the American Heart Association and the Dietary Guidelines - so this is a healthy approach.
Other ways to add fat/calories is to use "healthy" items like nuts, avocado and olives. You can add them to salads, sandwiches, casseroles, etc.
The butter spray is mostly chemicals and the fine mist that sprays out is why they can say it's no fat and no calories. That's on a "per serving" basis! Take a look at the ingredient list on the can and you'll see for yourself.
Please let me know if you need anything else.
