Thinking of changing caloric intake

After reading a little up on the issue and doing a few small/simple formula's I feel that I need to decrease my caloric intake a little during training camp do drop a few pounds of fat until the season really gets started.

First, I will be eating 175g of Protein from now on, instead of closer to 200-225.

Second, my BMR is ~1975kcalories. By playing hockey I need to add roughly 1000kcals/hr for that, along with exercise I would need to add even more. In other words, on a hockey+workout day, I might ingest 3500calories instead of my 4250-4500 now, and on a off day, I will probably only ingest 2500. I feel that after a month of trying this, I will have a better guesstimate on my maintenance kcal needs. All in all, I will be watching over each day how much kcals I need. Soon I will be getting a calorie, and heart rate monitor so hopefully I can watch these figures even closer.

Thoughts on Day 2 and 3 of Training camp coming soon today.
