Eating Long Term After Bariatric Surgery

Eating long term after bariatric surgery you will find is no different to how it was before surgery, the only key difference is portion control.

You will find that your portion of food at main meals will average a bread and butter plate after 1 to 1.5 years of your operation. This allows you to maintain your weight loss and calorie control your food without dieting.

Initially after your operation, you will have the support from our dietitians to provide you with the right bariatric diet and eating techniques that will help you recover, transition of different food textures, help avoid complications, and maximize short and long term weight loss.

 Our dietitians will also help you with advice on:

  • Obtaining all the nutrients needed for good health and managing specific health conditions such as diabetes, coeliac disease, food intolerances, heart or kidney disease.
  • Vitamin and mineral supplementation
  • Ensuring adequate protein intake
  • Practice mindful eating
  • Meal planning and weight loss goal setting

On your weight loss journey you will find the following “nutrition” changes will typically occur:

Initially, you can only tolerate fluids in your diet for approximately 1.5-2weeks after surgery. There will be no hunger, and you will be sipping a variety of drinks slowly.

For a period of 4-6 weeks, you will have changed the texture of your foods by blending, pureeing, mashing and soft mashed to make it easier for you to digest these foods and to help recovery.

Your portion of food intake starts off small at ¼ to 1/3 cup portion size, 3 times a day. Each person progresses to different amounts at different rates. By 6months from the date of your surgery, research shows that on average you can manage ½ cup of food at a time. By 1 to 1.5years after surgery, you will manage approximately 1 cup of solid food (bread and butter plate).

Mindful eating will be a skill taught to you to help you enjoy a satisfying, healthy and enjoyable relationship with food. It will help you break free from food rules and to enjoy eating a wide variety of nutritious foods. Mindful eating is not a diet.

We encourage making every mouthful count, meaning to choose a food that will nourish your body with goodness, rather than providing you with minimal nutritional value. Choose solid wholesome nutritious foods such as lean protein, fruits and vegetables, over poor nutritious foods or liquids such as soft drinks, ice cream or chips.

Some liquids such as fizzy soft drinks, flavoured coffee, cordial, alcohol, take-away smoothies can provide you the same energy as food, and are not as satisfying. These fluids will empty from the stomach quicker than solids, and can hinder your weight loss journey. Water is best, and we aim to drink at least 1500ml per day.

Eating until satisfied is an important skill to learn to help maintain your weight loss and make bariatric surgery a success for you. Eating until you are too full can cause discomfort, and repeatedly doing so can compromise your long-term success of weight loss. We can help you learn to stop when feeling full and to recognise when comfort/boredom/stress eating arises.

Vitamins and Supplements may be needed and adjusted to suit your health needs. Due to small portions of food in the initial stages, it makes it a little tricky to reach your calcium, iron, zinc, B12, and fibre recommendations, so vitamins and supplements will be recommended accordingly.

Eating long term after bariatric surgery allows a wonderful variety of foods into your diet and yet satisfied on a smaller portions allowing a much more successful journey to weight loss and maintenance.
