When? after starting the treatment XENICAL should I expect to notice weight loss?
Typically, people begin losing weight within 2 weeks of starting XENICAL, and may continue to lose weight for 6 to 12 months, at which point weight loss usually begins to level off - even if you�re still taking XENICAL. This doesn’t�mean that XENICAL is not working. People who continue to take XENICAL are better able to maintain their weight loss. Keep your doctor informed about your progress so that he or she can make sure your diet and your level of physical activity remain appropriate to your weight-loss goals.

The amount of weight you lose depends on how well you stick to a reduced-calorie diet with no more than 30% of calories from fat and an appropriate physical activity level, as well as on your compliance with the prescribed medication regimen.

If you believe that you haven’t lost any using xenical diet pill — or enough — weight, contact your doctor. He or she may need to readjust either the calorie restriction of your diet or your activity level.

The XENICAL dietary guidelines do not place any particular food out of bounds. But you may not be able to eat a lot of a particular food if it is high in calories or, especially, if it is high in fat.

So you can eat almost  all the food but its important to keep an aye especially  on food with high calorie ,if you want to obtain best results.
