Answer

Good afternoon, thank you for your question. I am sorry you have suffered with anxiety... I hope that you are now feeling better. Weight loss due to anxiety is a common problem, because of the obvious reason ( lack of appetite and subsequently,failure to eat enough calories to maintain body weight). Now that you are experiencing an improvement with your appetite you can predict a slow,steady weight gain of about 1 per week, given you are eating a diet with enough calories and nutrition. There is a very nice calculator here:
http://www.caloriecontrol.org/healthy-weight-tool-kit/weight-maintenance-calculator-women
where you can enter your statistics to see how many calories you require according to your height, weight and age. In order to gain back the weight you would need to increase your calories above that recommendation. If you increase your calories by 500 calories a day over the recommended number of calories foreach period of 7 days , you will gain one lb of weight, which is equal to 3500 calories. I hope this information has helped you, if so, please click accept. Feel free to ask more questions if you'd like. I am very happy to help you and I am very glad you have your anxiety under control!!
