A:  Your body is going through a transition. You are reducing the intramuscle fat and becoming more muscular. As you get more musclular, your body becomes more dense. You will not lose as much weight as you would expect (although your close are fitting you better). That is why I recommend that no one guage fitness success on weight oriented goals. As you become more densely muscular, then your body will more efficently utilize calories and you will lose the fat more quickly. Also, yes if you work at a higher intensity level you bypass the fat and start using the glucose and glycogens as fuel. I hope this helps.

Sincerely,
