I think you cut your calories too quickly, maxde1. I have this idea about strength gains and dieting, which is people stall/fail reps and sets whilst dieting not due to weight loss per se, but rather a lack of energy intake. It's a working theory. At any rate, I need some more info:
How are you tracking your food and what kind of protein/carb/fat are you taking in? At 6 feet tall and 92.5kg I have my doubts about you being fat, but I've been wrong before. Any idea of your current BF? What are you doing right now training wise?
