Meal Replacement Shakes for Weight Loss Surgery

The diet suggested before Bariatric Surgery is generally a Very Low Calorie Diet (VLCD).

The diet's goal is to increase surgical safety by lowering the size of the liver and fat around the organs, allowing easier access to the surgical region. A VLCD is intended to provide nutritional needs while being low in carbs.

Following a VLCD diet for as little as two weeks before Bariatric Surgery has been demonstrated to reduce liver size, fat tissue, and weight loss.

Making the surgery easier for your surgeon and a safer treatment from which you will recover more rapidly.

Frequently Asked Questions

Our Qualified Nutritionists are here to help you make the best choice when it comes to you and your health.

Mixing your shake with water will keep your "meal" within the caloric limit required for rapid fat loss. Adding milk will contribute more calories, protein and fats. This can be done if you are in a situation where you are attempting to gain weight if you have slipped below the suggested goal weight set out by your surgeon.

BN Slim shakes is highly mixable. The end result is always great in a blender, but you can also use a protein shaker with its own metal mixer ball to smooth out the drink by integrating the powder effectively.

You can heat the shakes without damaging the protein but bear in mind that some vitamins are sensitive to heat, so we dont recommend using boiling water.

Replacing all your meals with a shake is not recommended, even in the pre-op stage. Our bodies need food, and replacing all food with shakes means you will miss out on all the other healthy compounds found in healthy food that contribute to your overall health.

Yes, you can revisit shakes if you feel it helps you regain some routine in your eating habits. We suggest this is done with the other lifestyle changes needed to lose weight, and only for one meal of the day.

A sleeve/pouch reset is not viewed as a sustainable way to manage weight if poor eating habits have snuck back in after the honeymoon period is over. Long-term weight management success comes from prioritising portion management, moderation, behavioural change, and extra support from your professional team if you feel you have lost your rhythm or are experiencing weight regain.
