I am 14 weeks post op and have been eating about 700 calories a day. I have lost 50lbs but the last 5lbs have been a struggle the last month. I don't know if I am not eating enough or what it is. How many calories a day is the right amount to keep weight loss going?

Calories alone are not the best thing to go by. The first things I would check are that you're getting at least 60-80 grams of protein and 64oz of non caffeinated non caloric fluids. If you are, then how much are you exercising? It could very well be, especially if you're exercising, that you're not getting in enough calories. If that is the case, try bumping it up to 800-900 calories. But again focus on the proteins first. If all of your numbers are where they should be, then there is a good chance that you're just in a plateau Stick with it, be diligent and do what you're supposed to be doing and the scale will start moving again. This is a good time to mention the importance of taking body measurements so you can see that your body may very well still be shrinking even if the numbers are not going down. Good luck!

Thanks
