See how your weight progress compares to the average outcome in the SOS Trial

Bariatric Surgery Weight Loss Calculator - wait a moment for the calculator to load....


Note that these are averages and only indicate whether your progress is faster or slower than average. If you find that that your weight is higher than average for the period, discuss with your dietitian what may be the contributors. Remember that some things you can change and some, like your age are fixed and others, like behaviour can be hard to change, but possible with the right strategies.  


Simply enter your pre-surgery weight in kilograms and your height in metres, choose the approximate period since surgery and note your starting BMI along with typical outcomes based on the Swedish Obese Subjects trial, and our recommendation for protein intake during weight loss.
