Here's a few suggestions for you: first of all you can drop a level (or two at most). Some people have mentioned their calorie level is too high. However, it's important that you follow the amount of calories and fat at the level you are at so Alli can do the best job for you.
Unfortunately, there's not a way to change the log to a level different than the recommendations from the Personal Calculator -- but we're working on that!
Try the 1,600 level and 1,400 if 1,600 still feels like a lot, though I think you'll be fine there. Check p. 20 of the Companion Guide included in the Starter Kit for levels of calories and appropriate amount of fat for each.
If you check the Sample Menus in the Healthy Eating Guide - also in the starter Kit - you'll find menus for each of the levels + the exchanges for each of the foods included. Remember, you don't have to eat the precise foods on the Menus. You can develop your own menus with similar types and amounts of food.
I hope this helps.
