There are no specific foods you must avoid while taking Saxenda (liraglutide), but follow a reduced calorie diet and increase your physical activity, as directed by your doctor. If you experience an upset stomach and nausea with Saxenda, try these tips to help: eat bland, low-fat foods, like crackers, toast, and rice; eat foods that contain water like soups and gelatin; don't lie down after eating; get some fresh air outside; avoid tight clothing, avoid high fat, spicy or sugary foods.
