If it's as simple as calories in vs calories out....

Oh yea almost forgot to add in to my previous post you frequenting Wendy's and KFC along with Taco Bell and McDonalds. Congratulations on being the first person to ever have surgery like this and now have a diet of all fast foods and not be able to eat veggies because veggies is to much food.

You'd crap bricks if you saw the food diary of a DS'er that's a year out.
Many get more than 4,000 calories a day, all fat and protein.
Even the nutritionist told me to limit veggies.
I need 120g protein a day and that is priority number 1.

Having read through the thread I do have one question, are we talking about the same nutritionist that you consistently say knows nothing about DS and its requirements?

I was wondering the exact same thing!

It takes more than a day or two.

I should explain-- I'm guessing since one calorie level (945?) and one gain (one lb.) was mentioned, we were talking one or maybe two days. The body is not that predictable.

I agree with asking your doctor.

This part here sounds like a dream situation, and am surprised someone with this 'problem' would choose WLS: "This is the regular thing for me - eat less than 1,600, I gain or don't lose. Eat more, I lose."

Doesn't that solve your problem then? Just eat more than 1,600 and you lose?

Because your calories in can actually effect and change your calories out. Besides diseased body.

And all the calculators and Fitbit's go out the window for any decent estimate at that point.

Not to the point you'd stop losing, but easily to the point your eating level must be so low to lose, you don't adhere to the diet, and everything in surplus is fat.

Is the OP really claiming to be not losing on 945? I read the following as a clarification:

No one debated a calorie = a calorie. Only that I frequently eat way below my BMR and do not lose or lose very slow. I ate 900 calories a day for a month. Lost 10lbs. Ate 1,500-2,000 for a month with no change in exercise. Lost 17lbs.
I've lost 70lbs.

The OP also explained that the 900 calories were in the first post-op month and the higher calories more recently. Not sure if this is a debate with her (or his?) nutritionist, who is saying to eat fewer calories or what, but this really doesn't seem to apply to typical calorie counting.

First, losing 10 lbs in a month is hardly not losing or super slow. Maybe it's not what's expected after WLS--although the stats above about losing all the weight in the following year make me question even that--and without WLS it's pretty good. It's the most rapid loss I've achieved, and I considered it quite quick--slightly over the 2 lbs/week I was aiming for. Second, that the rate of loss might be less immediately after surgery seems quite unsurprising to me, although I'm not a doctor, so don't have the list of reasons why it might be. Seems a huge stretch to go to calories in vs. calories out not working somehow. That surgery might affect calories out plus there being special issues relating to the effects of the surgery on the digestive system seems quite possible and again not really an argument as the OP seemed to be making initially.

As for the 1500-2000, I have no idea if that's safe, and would be inclined to listen to medical professionals in this situation, but at the stated BMI (even after a loss of 50 lbs), that's probably still a large deficit, especially if only a portion is being absorbed, so 17 lbs, while extremely fast, seems hardly a violation of the law of physics or some evidence that eating more typically causes more weight loss, all else equal. (Obviously there are many other reasons to avoid VLCDs or an overly large deficit, although we can all debate what an overly large deficit is under particular specifics.)

So you mean to tell me you got WLS to "cure" Diabetes? LOL. That's a bit ridiculous if you ask me.

It's called Metformin, a HEALTHY diet, exercise, and eating at a caloric deficit. No WLS necessarily to "cure" Diabetes, which by the way, is not possible.

I guarantee you were eating McDonald's, Wendy's, Taco Bell prior to WLS which is how you ended up with a BMI of 63 in the first place. So when you say you've made "major lifestyle changes", no you actually haven't.

You wonder why you aren't losing weight… well it's simple, you haven't made any changes to your diet. It's very easy to eat 150 g of fat a day without shoving McDonald's/Wendy's/Taco Bell down your throat multiple times a day. Ever hear of avocados, nuts, seeds, olive oil, coconut oil? By the way, McDonald's burgers aren't meat, it's by-product.

I know multiple people who have undergone DS surgery and they sure as hell do not eat like you do. I know for a fact your doctor would be MORTIFIED if they knew the kind of foods you were eating.

I don't think you understand the ramifications if you continue to eat the way you are… At the rate you're going, you are basically eating yourself back to a BMI of 63, serious side effects of diabetes, heart disease, and more.

There is such a thing as adaptive thermogenesis - if you're eating too far below your TDEE, your body will adapt and your resting metabolic rate will plummet drastically.

Drop yes. "Plummet drastically"? No. Your basal metabolic rate can't afford to "plummet drastically". That's what starts to happen after your stores are so depleted that you're moving into true starvation (note this "starvation mode" BS).

If you're like me, it could drop to 400 kcals a day.

If your BMR dropped to 400 kcals a day you'd be a starving skeleton so emaciated and undernourished as to be on the brink of death. You'd barely be able to even move.

Coma patients don't even tend to have that low of a BMR.
