alli works most effectively when combined with a reduced calorie and low fat meal plan. Not sure why you are following a 0 fat diet along with the 0 sugar. Fat has minimal effect on blood sugars...
Here is some information you may find helpful:
Ask a doctor before using alli if you are taking medicines for diabetes or pre diabetes. There is no drug interaction between alli and diabetes medications; however, people with diabetes or pre diabetes may have lower blood sugar levels and improved glycemic control after losing weight with alli. This may require a dose reduction of their diabetes medication. Hope this helps.
