Does your pre-op diet weight loss "count"?

when it comes down to it, does it really matter?

I have a tendency in every aspect of my life to set unrealistically high expectations, so I'm trying to manage that, which is why it matters somewhat to me. For me, it provides peace of mind to see numbers (totally get that not everyone feels that way).

For background, I was watching John Pilcher's "Real Weight Goals" video, and he says at the 3 month milestone (which is approaching for me), you've generally lost half the weight you're going to lose. He says "not the weight when you first met us, but the weight just before surgery." I got caught up on that phrasing and couldn't figure out if he meant literally the day of surgery or the day you start the pre-op prep, which is a pretty big difference for me. So I was hoping for a more definitive answer on how doctors calculate this type of thing.

ok,so if i were to respond to this specific statement then, my surgeon made his calculations with my weight when i first got accepted into the program...which was 2+ YEARS BEFORE my actual surgery (long story, but i backed out twice before i finally went through it).

granted, for ME, it didn't really make a difference because i was the same weight on my acceptance date in 2016, as i was 2 weeks prior to my surgery date in 2018. but im sure many others could not say the same if they were to use the same barometer.

long story short, "excess weight" is arbitrary, and the calculations are different depending on who you ask.

your best measure of success and progress in the endeavour of weight loss is yourself. is your weight loss graph trending down? yes? then YAY! again, you are doing great...but you don't need me (or anyone else) to validate that, you can see it yourself in your numbers and hard work ❤️ .

I think a lot of us fall into numbers - we are bound to at least at some point.

Unfortunately I don't ever think there is a doctor/scientific answer to really calculate it. It's almost the same as why we all have so many different programs - not only our bodies are different, but every doctor has a different take in their "expert opinion".

I just had my 1 year post-op visit on Monday, and my surgeon definitely counts my weight loss total from the date I had my consult visit January 2023. I have always kept 2 running totals from before my pre-op diet to the day of surgery weight. Personally I feel like all pounds count and it's an accomplishment to see those numbers go down both before and after the surgery.

Calculates me at 182 at 18 months. Which I would have been thrilled with. Even more thrilled to get lower but honestly I had not *that* much of a say in it. My body kind of decided. 🤩

At my highest weight its tell me 188lbs at 18m but my pre-op weight its tell me its 179lbs. However in both scenarios I am weighing less than the 6months weight and I am 14weeks post op. So hey I call it a win!

Using my day of surgery weight, the calculator suggests I'll be 195lbs at 3 months. I'm 204.4 today, but assuming this blasted week-long stall breaks soon, it seems likely I'll be somewhere around there in another 26 days. It tells me to expect 178lbs at 3 months and 158lbs at a year, with a low of 151lbs at 18 months. I would be pleased as punch with that if it happens! That would be exactly 100lbs down from my highest weight, which seems unreal.

totally doable!! You got this!!

I find the calculator on the Mexico site to be rather inaccurate for me, but everyone varies. Age and surgery type, as well as co-morbidities all impact weight loss rate. It thinks I should be at 212lbs at 6 months but I'm at 240 with 6 days to go. Not gonna happen. It also thinks I should be at 170 by 12 months, but that's not very likely either.

I've always used the following one as it takes into account the different surgeries and looks just like the one my surgeon uses. They calculate from the highest weight, it is important to include that because if you have a lot of weight loss before surgery your percentages may track differently and your post op weight loss may be slower. I've seen this happen to several people with surgeons calculating it improperly, or applying the bypass trajectory to a DS patient, which is a disaster and very stressful for the patient! This one takes into account much more like your age, ethnicity, and pre-existing conditions:

According to this one I should be at 78 lbs down for my DS surgery at 6 months. I'm at 80 lbs down. My weight loss has tracked along with this thing pretty steadily, give or take 15 lbs, since surgery, except for my 6 week stall. It puts me at 202 by 12 months out, but DS patients lose for 18-24 months post op, so I should be at 170 sometime in that 12-24 month period!

In the end these are all just estimation tools. Our bodies do what they will and we make the most of it. Still, it is nice to have a loose guideline to follow.

All those calculators are just averages so try not to get too caught up in what they say you’ll have lost at certain times. Some will lose more. Some will less. Some will lose as they say. That’s how averages work. And it may change time frame to time frame. Treat it only as an idea of what might happen not what will happen. You may end feeling like you’re failing if you look at their results as gospel.

This one took a little more math since they give you pounds lost instead of what weight you will be, but I liked that I could see it month my month. The funny thing is the risk calculator one is more aggressive/optimistic in terms of my weight loss. The Mexico one says I'll be 195 at 3 months but the Risk one says 5lbs lower. Oh well, as everyone says, this is just an average, no matter which calculator you look at. But I do find it helpful to have an idea of what to expect. It keeps me realistic.

I think it counts. When I list my high weight, for example, it is my highest weight ever before WLS. That is different than pre-surgery weight, which was my weight on the day of the surgery.

Congrats for your success and wishing you continued success.
