As a result of a particular medication, I somehow managed to gain 35 pounds from August 2014 to August 2015. In the last two months, I have been doing some fast walking for 45 minutes for aerobic exercise. I saw a dietician and she said that I wasn't taking in enough calories and that my body was in starvation mode...even when exercising, though I saw myself losing some unwanted "stomach"...I wasn't losing weight. She gave me a proposed diet which added some calories that would be beneficial to me.
