Before I add my personal 2 cents, the bottom line should be judging your own progress. Are you consistently losing weight each week? Out of the weight lost, what percentage came from fat vs lbm?
With that said, I would think that your 1,600 calories is to low for your overall weight and that this would cause additional lbm loss and limited overall loss. Also I think your protein is way to low, specially while on a cycle. At a minimum I would suggest at least 1gram per body weight. 2grm per weight is usually suggested for those on a cycle (no clue how people could eat that much protein though).
Personally I'm going in a completly different direction, bring on the red meat and fat....

and on a carb cycling diet such as The Anabolic Solution it makes having the occasional cheat meal/day benificial to your overall progress. Again let your own progress dictate any adjustments you may need.
