Weight Calculators

I’ve tried to project my Future weight with a half dozen weight calculators. They seem kind of mixed but I’m hoping to beat the ones I’ve used.

Pre surgery weight 305

surgery weight 283

current weight 267 (13 days post op)

I would love to get down to 150-155. Most calculators say 200 ish

do you use the projections / statistics Has anyone beat them by a lot?

  • I was 291.8 7 days after surgery. HW was 320.0. Goal weight was 170.0 to be at normal weight/ BMI. CW Is 145.6. I used the weight calculators too. Good luck on your journey.

    At my initial consult with my surgeon, when I weighed 229 lbs, he said he thought I could get down to 140 lbs. Post op appointment he changed it to 130. On my last visit I weighed 125 which was 93% of

I am glad I found this thread. I was watching some of Dr. Weiner's videos yesterday, and used the calculator he suggested (from Michigan BSC I believe) and it totally deflated me. Per that calculator, according to my age, gender, starting weight and my medical history I should expect to "only" get to 195, a disappointing number for me, and I totally let that get in my head. I also am aware that even though for me I am moving a lot (11-15,000 steps per day, with a weekly average of over 12k a day), moderately brisk walking will not spur weight loss. I spent a lot of time with better self talk, i.e. I want to walk so I can enjoy my time with my family, I love moderate "hikes" and have neither the inclination nor the ambition to hike the Alps, losing 65 pounds is a "lot" so 195 is a whole lot better than where I started, etc. However, with everything else that is going on in the world that number took on a whole lot more meaning that I should EVER have let it. Much happier running a few other calculators showing a lower number! Also, that I am currently at 40 pounds, so even if I "only" lose 5 this month, if the double your weight loss at the 4 month point holds true I'm at 90 pounds on that calculator.

The honeymoon of the first few months is waning, and I am spending too much time in my head. I'm eating healthy, moving more, and feeling good. Why can't I stay in the moment and be grateful?

those are averages. The average bariatric patient can expect to lose 70% of their excess weight. However, as with any average, there are people who fall on either side of that. There are plenty of us around who have lost much more than that. If you're committed, you can too.

Thanks @catwoman7. Most of the time I feel committed, though lately sometimes I feel like I should be committed! lol. Hope you are staying well, and, as always, I appreciate your feedback.

I had forgotten about this thread. Thanks for commenting!! Here was my predicted numbers:

  • 80% of patients reach at least 212 lbs 18 months after surgery.
  • 50% of patients reach at least 193 lbs 18 months after surgery.
  • 20% of patients reach 174 lbs 18 months after surgery.

Im almost 6 months out and 185 lbs (-120lb total). So I guess you can beat the calculator. I’ve been fairly strict on food choices, not that strict on water (I know...shame), and have gotten a lot more active. It’s a little off because I used pre liquid diet weight bc it wouldn’t let me do it after with the BMI rules. (Too low and it says you shouldn’t have surgery)

I used the calculator in the link out of curiosity. I never expected to reach goal let alone surpass it, despite metabolic disorders and inability to exercise amongst other things. Albeit I’m probably fairly obsessive since I have taken a daily log of weight, meals, protein and calories. And stuck with low carb. With exception of adding banana to my yogurt now. And since I don’t snack usually an apple. I’ve increased calories gradually. And still adapting. And struggle with that fear of regain.

According to the chart:

GASTRIC BYPASS

  • 80% of patients reach at least 145 lbs 18 months after surgery.
  • 50% of patients reach at least 132 lbs 18 months after surgery.
  • 20% of patients reach 119 lbs 18 months after surgery.

Of course the chart is based on my starting height and weight I entered. I’m 5’ started at 208lbs. I hit one year April 29th. And my current weight is 102lbs.

I don’t think I actually processed that I lost 106lbs and I’ve not been this weight as long as I can remember.

Calculate How Much You’ll Weigh 2 Years After Surgery
https://www.obesitycoverage.com/how-much-will-you-weigh-after-surgery/

The calculator gave me a number and let’s just say within 6 months I was lower than that and still going. Calculates don’t mean anything everyone’s metabolism and body works at different speeds. Just a tip If you go according to those things you’ll end up disappointed that you won’t lose as much as you want to or that you lost less than you should have....
