I lost 90lbs during the year before my VSG by being on a 1500 Cal diet and lots of walking. Since my VSG on August 20th I have lost an additional 25 lbs but I hit the dreaded "three week stall" for the past week. I hope I start losing again soon. I am averaging only 500 Cals a day and run out of energy by mid afternoon. Unfortunately, I have to go back to work next week. I hope my energy holds out.
