Do you think it is possible that exercising 2x a day is being counter balanced with food intake? Was happening to me all the time before WLS. I would exercise 2 hours a day, but my diet was just not right and thwarted all my hard hours spent exercising. I am sorry you are going through this. Can you share a breakdown of what your diet looks like? Another thought, which would seem implausible at first, is exercising 2x a day is too much for your body and it is in starvation mode. However, Looking at your diet seems like a more logical and plausible place to start. Have you tried talking to a nutritionalist?
