From exrx.net (hardly a definitive source) the recommended amount of fat is between 20% and 35%. Less than 20%, and you risk inadequate vitamin E and fatty acids. More than 35% and you tend to get too much saturated fat (not the best thing for you), and it's harder to keep the calorie count down.
My understanding is that Alli reduces the amount of fat absorbed by your body, meaning that if you eat 1500 calories in a day, 30% of which are fat, and take Alli, you will actually be using 338 cal of the 450 cal of fat you consumed. This is equivalent to consuming 1388 cal, with 25% of that from fat and not using Alli.
(based on 25% figure from medifast1.com/community/downloads/alli_medifast.pdf)
The mayo clinic website states that the weight reduction is rather slight. With those figures, it seems hard to justify the cost and additional risks associated with Alli.
From your pictures, you're already doing great, I do not think you should go around messing with your digestive enzymes.
