Losing Weight before Surgery: How to Shed Those Last Stubborn Kilos Before a Procedure

How to Shed Stubborn Kilos Before Bariatric or Body Contouring Surgery

Once you’ve made the decision to get bariatric surgery (or contouring surgery after you’ve had gastric banding or a gastric sleeve), it’s time to dedicate your efforts to getting prepared for your procedure, including losing weight before surgery

You’ll have to lose some of the weight on your own before surgery, but fortunately there are specialists who work with the nutritional and psychological aspects of undertaking a major lifestyle shift – such as undergoing gastric surgery and completely changing your eating habits.


Excess weight

You may not know that bariatric surgery – such as gastric sleeves or gastric banding – won’t take off 100% of all the weight you want to lose; only 70%.

That means you’ll still have 30% of your excess weight after surgery – unless you lose some of the weight before surgery, which has many benefits in the longer run.

For many patients, losing 10 to 15 kilos before going into gastric surgery (as an obesity treatment) is going to make you – and your doctor happy.

Insider Tips to Losing Stubborn Kilos BEFORE you have Bariatric Weight Loss Surgery

Here are some of the most successful secrets of top nutritionists who make it their mission to do everything possible to help clients release excess kilos before going into bariatric – or post-gastric banding body contouring – surgery.

11 Tips To Help You Lose Weight Before Your Gastric SurgeryBalance

1.      Get familiar with the numbers

First of all, it helps to know how to calculate the expected weight loss from your pending bariatric surgery.

Let’s say you weigh 75 kilos. Subtract your ideal body weight of 61.36 kilos from your present weight of 75 kilos to get 13.63 kilos.

Now take 70% of this amount to get your expected weight loss from gastric bypass surgery, or 9.54 kilos.



That means that you’ll ideally have to aim to lose the remaining 4 kilos – on your own – prior to surgery.

If you’re getting the gastric sleeve surgery, you’ll have to increase the amount you reduce before surgery by about 1.36 to 1.6 kilos, or 5.68 kilos.

If you’re getting the gastric band surgery, the number goes up even higher by another 1.36 kilos to 7.2 kilos.

Here’s another example. Let’s say you weigh 150 kilos.  Your ideal body weight is 62 kilos. That means 88 kilos have to come off but only 61.6 will come off with the surgery.

In this scenario, you will have to take off 26.4 kilos on your own.

2.      Ask Your Surgeon or GP For a Healthy, Safe Method of losing weight AND stick to a suitable exercise program

Your Surgeon or GP may have a liquid-based nutritional suggestion or a modified eating regime that he or she prefers you to use to help reduce your weight prior to your weight-loss surgery.  Be sure to ask for any support you need as losing weight can seem easier when you know others are supportive of your efforts.

You’ll also need to exercise to your abilities, with professional advice to minimise your risk of injuries.

Sport against overweight

3.      Plate Size Reduction

Start reducing the size of your meals now.

You might decide to simulate what it will actually be like – after gastric surgery – when your stomach’s capacity is only ONE cup. This means your protein plus vegetables plus bread and dessert  – all these may not exceed 1 cup volume. It’s a sure way to lose the weight and may also help you psychologically prepare for smaller portion sizes.


4.      No More Sugar!

It may be ideal to try to eliminate sugar completely from your daily eating regime.

This is one of the quickest ways to lose weight – plus lose the cravings that go with the sugar.

You may not realize it but 1-1/2 hours after you eat a food with sugar, more food cravings and sugar cravings emerge because of the blood sugar reaction that occurs after consuming sugar.

5.      Do Some Studying about Glycemic Index and Digestive Responses

Look up information about the Glycemic Index and then aim to eliminate all high Glycemic Index foods. It’s usually quite shocking, at least initially, to discover that the list includes all foods made from wheat, which has been genetically modified over the years.

You’ll start to notice that you’ll need to incorporate a lot of leafy vegetables and other low-GI foods into your eating routine.

Good food

All the genetic modifications made to wheat in our diets has potentially brought many people to states of insulin resistance. Test this for yourself  for a few weeks – omit the high Glycemic Index foods from your eating plan for at least two weeks, and see how your body loses weight without other major effort. It may surprise you and you may want to continue following a low GI diet.

6.      Allergy Equals Inflammation: Stop eating the foods your body doesn’t respond well to consuming

If you’re allergic to certain foods – and admittedly, it’s not always easy to tell unless the allergy leads to a severe reaction – then try to eliminate them from your diet immediately.  It can be very interesting to see what effect this has on your entire well being, because allergies cause inflammation, and inflammation impedes your overall health. The reaction of an allergy is on a cellular level, too, not just a reaction causing you to have puffy eyes, itch due to a rash – or suffer indigestion.  Allergic foods can hold inflammation in your body, which can also lead to water weight (retention).

7.      Stay hydrated: You Must Drink Water!

Good food, and sport

No one can lose weight without drinking water during the day; it’s essential for the breakdown of fat. Two litres is a minimum per day if you really want to lose weight.

8.      Are You Eating Enough Protein?

Your daily protein intake should be:

  • your body weight divided by two = the number of grams of protein needed for the day

This usually means a minimum of 25 grams per meal. When your protein intake approximates your physical needs, then you will find cravings for high-carb foods will dwindle.

9.      Are You Getting Enough Nutrients?

Is your vitamin and mineral supplement plan adequate to match your body’s needs?Arginaid

Checking with a nutritionist who is well versed in this goes a long way towards taking off the stubborn kilos before your surgery.

The reason why is because all the nutrients work together in orchestra-like fashion in the body.

Not having enough zinc, niacin, or chromium interferes with blood sugar metabolism.

Not enough B vitamins results in lack of energy and inability to digest proteins, fats and carbohydrates.

Get all the nutrients you need – life goes a lot better when you do as does weight loss.

And if you’re having post-weight loss body contouring surgery with Dr Richard Maxwell at Cosmetic Surgery for Women or Aesthetic Surgery for Men, you’ll be given a Rapid Recovery kit that includes special supplements proven to aid in cellular renewal for improved healing processes.

10. Stop the High Fructose Corn Syrup Drinks

High fructose corn syrup drinks and food products tend to pack the weight on people fast – plus it can end up causing liver problems.

Give these fructose laden drinks up NOW; and replace them with water instead – there’s no nutrition in them and they are full of calories and questionable chemicals.

11. Stop Eating After 6 pm Each Night

Increasing the length of time you go without food (e.g., fast) in between your last meal of the day and your breakfast meal – seems to help speed up your body’s ability to lose weight.

Achieving your ideal weight is often a lot more attainable with Bariatric Surgery. But you can’t depend on the procedure itself to get you completely to the weight you’d like to be.

Plus, after Gastric Surgery, you’ll likely need to have body contouring surgery to remove the redundant skin folds or excess fat to regain a more natural-looking body contour after significant weight changes.

You’ll also need to be at a stable weight for the body contouring surgery.   So learning how to eat healthily and in your body’s best interest can go a very long way in helping you become fitter, healthier and more body-balanced over time.




So even with gastric banding or gastric sleeve surgery as a treatment option for obesity, you’ll still have to do change your lifestyle patterns and eating regimes BEFORE – not just after – your surgery to get the best weight change results as well as help minimise your surgical risks.

You CAN lose the weight.

The first step is believing it’s possible within yourself.

The second step is making a commitment to change, including getting the external support you need to boost your motivation to adopt the lifestyle, exercise and eating changes over a longer term of time.

Make it your goal to use these weight-change strategies starting today, and let us know if we can assist you with post-bariatric body contouring for excess skin reduction once you’ve reached a stable weight.
