You’re not alone.

Gastric Bypass Surgery for Weightloss

If you’re really ready for professional help with weight loss and you need no further motivation to lose weight, it’s time to consider weight loss surgery.

A gastric bypass will seriously help you with how to lose weight fast and keep it off long-term.

Just How Much Weight Loss?

How much weight you lose will depend on a few things:

Weightloss Surgery

Weightloss surgery may be a solution if you are chronically overweight

  • Exercise
  • Diet
  • Lifestyle
  • Your commitment to how to lose weight and change your habits

While the size the surgeon reduces your stomach to will make a difference in weightloss, the surgical differences can be somewhat minor.

So let’s assume you do everything right post-op. You change your diet, you indulge in physical activity daily and you make sure you’re moving more than you’re sitting. Just how much weight will you lose?

Average Weight Loss with a Gastric Bypass

Take a look at the average weight loss post-surgery. Different people are different heights and weights and therefore different BMI’s (Body Mass Index). So here’s an example:

Joe is 6”2 and weights 180kg. He’s going to lose a different amount of weight to Mary who is 5”2 and 90kg. However, both patients will lose a similar percentage of excess weight.

Joe’s journey:

  • Joe’s ideal weight is 87kg and he has 92kg of excess weight
  • He loses 65% of the excess; 60kg
  • 2 years after surgery his new weight is 120kg

Mary’s Journey:

  • Mary’s ideal weight is 66kg
  • She has 24kg of excess weight
  • She also loses 65% of the excess; 16kg
  • Her new weight 2 years after surgery is 74kg

So both patients lost the same percentage of excess weight. On average, gastric bypass surgery helps patients to lose around 70% of their excess weight so it’s a good number to work with if you’re trying to work out your expected weightloss.

Calculating Your Expected Weightloss

  1. Ideal Weight

Workout your Body Mass Index (BMI) using an online calculator.

  1. Excess Weight

To work out how much excess weight to lose:

Current Weight – Ideal Weight = Excess

  1. Expected Weight Loss:

Excess Weight x .70 = Expected loss

  1. Calculating New Weight:

Current weight – Expected Loss = Post-Surgery New Weight


Remember that 70% weightloss is merely an average. Everybody differs and some people can lose a lot more. Ultimately the success of the surgery will come from having realistic expectations and changing your habits for the long-run.
