Congratulations on your weight loss so far. That's a great accomplishment! It sounds like you may be at a plateau - a time when the body decides to take a "time out" to adjust to all the changes - and your weight loss will resume. You might want to take a look at a few things to get it going again.
If you are feeling "fluffy and puffy" you might want to take a look at your Nutrition Logs and check your sodium intake. The recommended amount is 2,300 milligrams - or less - per day. If the levels are 3,000 mgs. or above you may be retaining water. That will hide a weight loss and leave you feeling bloated. Reducing sodium/salt intake is the way to get rid of it.
Sometimes it's a good idea to start weighing and measuring everything you eat and drink for a week or two. That's the best way to ensure accuracy + it's a great lesson in learning what portion sizes "look" like. Sometimes some extra calories can sneak in and it's just enough to hold weight rather than show a loss.
Yes, it's important to have the recommended amount of calories and fat for best results with alli. There are two great posts on why calories and fat are so important. Try to take a look when you have a chance; it's great information.
Finally, it may help to increase the amount and intensity of your walks. Your body gets accustomed to a certain level of exercise, and then a change is needed. Walk faster, longer to get a better effect.
I hope this helps. Please let me know if you need anything else.
