If it makes you feel any better, I don't eat a whole lot more than you right now and my surgeon is also ok with it. My average calorie intake is about 350-500 most days. I do get my recommended Protein and fluids in.
You may have somewhat of a stricture, my doc thinks that's my issue, but since I can get all my protein/fluids in he wants to wait and see if it resolves itself.
The lack of energy is a bit of a concern and I would wonder if my blood work was all in check if it hasn't been tested.
I can assure you it is possible to have normal energy levels without much food as I don't lack energy.
I am a little over 2.5 months out from surgery. I am not losing as fast as you, but am down almost 60lbs post-op along with 45 pre-op.
Just the last week or so I've been able to eat a little more (eggs, refried Beans, cheese sticks, deli turkey). But my amounts are still so small that even 3 meals a day of just Protein heavy foods and I can still only get about 30-35g of protein from food. The rest I have to drink.
Anyway, just thought it might help to know you aren't alone in this.
And of course, listen to your surgeon. And if you aren't confident in his answers I think checking with your primary care doc is also good advice.
