I struggle daily.
I completed a round of optifast. 500 calories a day, for months. I lost 20#. Good news was 16# were fat, not all muscle loss. Bad news, I gained it back plus 20 when I went back to eating.
I cut out soda. I decreased Starbucks. I started going to the gym.
By the end of 2013, I was going to the gym 5 days a week. Sometimes for 2 hours. I switched between treadmill, elliptical or rower for 30-60 minutes. I tried to keep my heart rate in the fat burning zone. Then I would hit the weights. NO WEIGHT LOSS!!
Frustration and acceptance has set in.
