Post RNY and/or Sleeve: Different Daily Calories in Maintenance?

[gina171 626]

I am sure this must be out there somewhere, but I can't find it? If you could direct me to s post or site that would be so appreciated.

Let's look into the future.....and you get to a maintenance weight of say 150 pounds......would the amount of calories you consume daily be DIFFERENT if you chose RNY vs. Sleeve surgery? Or vice versa?

Is there a surgery that allows you to eat a generally higher number of calories in maintenance? How significant is the malabsorption of calories with RNY?

Thanks

Good question, I'm interested too.

I'm guessing it all depends on the person and the type of calories.

I think DS is the only surgery that is going to give you more calories once you hit maintenance. Gastric bypass starts out with caloric malabsorption, but after about 18 months your body figures out how to efficiently absorb those calories again, and the malabsorption component fades away. The duodenal switch has more powerful and longer-lasting malabsorption effect, which is why it is the most effective weight loss surgery there is.

At least, that is the way my surgeon explained it to me.

I agree with @@Bufflehead , that is basically how it was explained to me. And yes, most people lose their malabsorption as time goes on which is why, long term, the sleeve and the bypass results end up about the same.

If you are trying to pick surgeries based on the one that lets you eat the most long term, you might need to think about why you are having surgery and the kind of life changes you are willing to make.

RNY gastric bypass patients lose weight quickly and then enter Maintenance phase. I was in Maintenance after about 7 months. Sleeve patients lose weight at a slower rate before they bottom out. Some continue to lose weight for 2 years after surgery. But once in Maintenance, the caloric intake between RNY and the sleeve is probably the same. I discussed my perception of the Maintenance phase in the following article. http://www.breadandbutterscience.com/Surgery2.pdf

After about a year out from RNY surgery, the intestine realize that the stomach is no longer processing fats and sugars and steps up to the plate and takes over that function. So at that time fats and sugars could be eaten without causing dumping syndrome. But for RNY patients, their bodies will never again synthesize Vitamins from the food they eat, so they have to continue to take Vitamin supplement for the rest of their lives.

I've had the sleeve and am two years out and in maintenance. I eat around 1,200 calories a day and eat low carb less than 140 grams or I tend to gain a couple of pounds over what i am.

I had sleeve WLS 22 months ago. I've been in maintenance for 14 months now (I weigh 135 pounds). I'm a 70-year-old woman.

I eat 1700 - 1800 calories a day.

That's what's working for me.

For now.

P.S. Based on the millions (literally) of WLS forum posts I've read in the last nearly 3 years, there apparently is no "standard calories per pound to maintain your weight" for any specific WLS procedure. What a WLS patient's maintenance calorie budget is depends on their individual metabolism, which is a function of age, gender, activity level, ancestry, muscle mass, and God knows what else.
