I seem to be stuck at about 400 calories a day no matter how hard I try. (I get 60-80 grams of protein though) I can't seem to eat more than about 4 bites. My dr wants me to 800 before I can work out and I'm very anxious to work out. Any tips on getting calories up?

How far out from surgery are you? I found for the first 4-6 weeks I was at 500 or less. Now I have started to get some hunger back and am working out. I typically eat between 700-900 daily now. I'm almost 10 weeks out. I do have to eat some snacks (cheese strings, yogurt) during the day in addition to my meals to get the calories up. I also drink a protein shake daily. My surgeon would like me to eat 1000 calories/day, but I find that hard to do with healthy choices simply because of stomach space/timing issues with water consumption!

4 weeks out and not even at 500. I have to be reminded to eat. I have been as low as 170 in a single day in the past two weeks. The trick is, I know I won't have the energy to workout if I don't get the required Protein, so I used that as an incentive to get up to about 500 so at least I'll go for brisk walk/jog.

Personally, I have been tolerating food well, but they fill me after a single bite. I had a 38 inch bougie, which is middling, but the restriction of anything but Clear liquids is still quite severe. However, this is nothing I would ask to have changed, as I am satisfied with my weight loss so far and have not yet hit a plateau. If I start to be able to eat more and then hit a plateau, I'll wish I had this back.

Eat more often.

My goal is 100 grams of Protein a day, so I eat four, five and sometimes six times a day to reach that target. And, I don't go to bed until I do.

Plan out your Snacks and meals, track your food, use protein supplements in your fluids, set a reminder of you are forgetting to eat, and keep trying. It does get easier.

I'm 6 weeks out.

I am 3 weeks out and still eating under 300 calories.

I am looking forward to getting more in, but mostly am focusing on protein and fluids.
It's still a challenge for me to get in 60 of each

Your fine, that's normal. Low calories is the point. It's good your getting in your protein. I say go work out. I've been on 400-700 calories for eight months and al it done for me is give me amazing results and I'm very active
