I have been working really hard with my weight-loss, I exercise more than most people I know in my weight loss group, 65oz of water per day, 20-25 carbs, Veggies, Lean meats, no sugars, you name it, I've been doing it. I am also HypoThyroid and on 50mcg of Levothroid. My weight loss had been a upward battle, very hard battle.
Anyhow, I spoke to a Dr. on the phone (My Dr. is out on leave), she looked at my chart and said that as we get older, we exercise less. I am only 35.
