I have Aetna insurance and they require a 90 day supervised diet. I go tomorrow for my 3rd visit with the nutritionist. I am not having any luck on loosing or maintaining my weight. I have gained 3 pounds and I have been documenting in a journal daily my food and exercise. I am getting my daily water in and walking 30 minutes daily. The last couple of times I have seen the nutritionist she's only given my advise on portion control and chewing 20x per bite. She has never set any calorie ranges or other goals to work on to help me loose. However even with portion control and walking I am gaining, now I am terrified that Aetna choice POS II will deny me. My BMI is 45 and I have diabetes, high cholesterol, and PCOS. Can anybody tell me their similar experience with weight gain during 90day diet and insurance approval. Thank you.
