Roxy, do your RDI and track how many calories you intake every day. Don't worry about how many you burn, just focus on your intake. I will bet you are taking in more than you think. My doctor told me when I first went to her about losing weight (my weight loss doctor - I call her my fat doctor) she said, the first exercise we are going to teach you is push-a-ways. I heard of pushups but never push-a-ways. She said, you are going to learn to push away food you like to eat and eat the food that you need to eat. When I stick to her plan it works. My problem is I have to have the will power. It waivers too often for me.
