What's the expected rate of weight loss with VGS for low BMI patient.

Hello,
Thank you for your question and congratulations on your surgery! 
In my experience, patients tend to lose 20-30 pounds in the first month and average 10 a month thereafter. That said, it is not unheard of for patients to lose little weight the first few months following gastric sleeve surgery. It is also common for patients to have periods of stalled weight loss. Factors that influence the rate and total weight loss include gender, age, starting BMI, and extent of lifestyle changes. Your results appear to be within the expected range of weight loss.
From what you share, you are doing an excellent job sticking to the recommended diet. I caution you to avoid puréed and soft foods and be careful you do not consume too many liquid calories. It is much easier for sleeve patients to consume too many calories through liquids than with solid food. This is because the liquids are digested more quickly than the solids, allowing the patient to more easily "overeat" if consuming high-calorie liquids. Excessive liquid calories can stall and even reverse weight loss. It’s also important not to consume liquids with solids since it can push the food more quickly through your stomach. 
Exercise is also very important: at this point the goal is 45 minutes of daily exercise. 
Follow up care with your surgeon and support team (ideally including a therapist and nutritionist) is essential. It’s also important not to feel discouraged during these times; it can take time to see the results of your lifestyle changes.
Kind regards,
Dr. Moein
