You're asking a very personal question that others may not be able to answer adequately. Your calories goals will depend on how much you weight, how tall you are, your metabolism, and have active you are. For me personally, I have MFP manually set to 2000 calories. By default it wants me to be getting about 1800. I manually calculated mine, and they seem to be working for me. However, I don't eat my exercise calories as a general rule, so that is an extra 2600 to 2800 calories a week that I know I burn and don't eat back. That's 1/2 a pound right there. I've also had the RNY, so my procedure is mal-absorptive. It means that I don't absorb nutrients in food as easily as others. I'm 195 lbs and have a sedentary lifestyle with the the exception of the 4 to 5 hours a week I spend in the gym.

If you are worried about it, you can manually set your goals. Might want to check out a website such as iifym.com and do the iifym or at least the TDEE calculator. I've found if you are honest on the calculators then it gives you a fairly accurate calorie/macro goal. That's how I have manually calculated mine out.

I know from reading these forums for a few months now, the advice many people receive when they aren't losing weight is to actually eat more calories. Maybe try eating an extra hundred or two hundred a day? The reason for this is that if the body isn't getting enough calories, then it tends to hold onto them and doesn't release them for energy. Are you finding yourself worn out, or have a general lack of energy? Lack of calories might be the reason. Also, are you weighting or measuring food? Measuring food is not accurate at all. If you measure you should invest in a nice digital scale. You'd be surprised at how much extra food you are eating if you just measure!

Thank you, I will check that website out. Funny you mention fatigue. BIG YES! I have gone to bed at 9pm for days and days. I normally am ready at 10. I'm about to fall asleep at 8:30 but force myself to stay awake. I don't weigh my food but I eat out of 1 cup containers. That's supposed to be the amount I can eat at a sitting so that's how I do it. I'll keep plugging away and figure out what works best but these tips help.

I was told one cup servings as well, starting at about 1 year post-op. I vastly exceed 1 cup (8 oz) of food in a sitting. I've been known to eat 12 or 13 oz of food at a time. What I've done is go to more calorie counting than anything else. If you go that route, then make sure you invest in a good digital food scale. I actually did an experiment with oatmeal one day. I did half a cup (1 serving) of oatmeal, then weighed it. It came out to 57 grams. The serving size of oatmeal is 40 grams! That means in that half cup measure I was fitting almost 1.5 servings of oatmeal! Weighing is definitely more accurate for solid foods. I still measure liquids though.

I really do hope this helps. Maintenance is the hardest part. Tracking your food intake will never go away. I fully expect it to be a battle that I will fight for the rest of my life.
