After weight loss surgery it is absolutely essential to follow a specified eating regiment that will ensure that you properly heal and obtain adequate nutrition. Weight loss surgery is a surgical “tool” that can help you reduce unhealthy weight and body fat. The number one reason for failure of weight loss surgery is not following the post surgery diet and modified exercise program prescribed by your weight loss surgeon or dietitian.
Ideally, your diet should have changed before bariatric weight loss surgery to get you into the habit of eating more protein, eating less and eating healthy. Immediately after your weight loss surgery, your eating habits will drastically change in ways that will have a major impact on your lifestyle - for the rest of your life. After surgery, it will generally take about 9-12 weeks for you to gradually progress to eating solid foods.
It is very important to strictly comply with your physician's or dietitian's recommended diet guidelines.
