Hey guys - I've thoroughly enjoyed the Primal Blueprint and have had some success establishing many of the changes described in the book. I'm ready to take it to the next level. I'm about 6'4" and weigh 246. I'm probably around 20% bodyfat. I'd like to start losing some weight, specifically fat. I'd like to cut carbs down to around the 75g range. Can you guys tell me if you think this sounds like a good plan?

Roughly 3100 maintenance cals - so I'm aiming for 2600
250 grams protein
75 grams carbs
145 grams fat

This means 50% of my daily calories are going to come from fat. Is this too drastic of a change? It's roughly a 500 calorie drop. My plan is to include carbs in my first three meals of the day (breakfast, snack, lunch) and no carbs afterwards. I'm thinking of 25g carbs the first three sitting through potatoes, fruits, etc. I know I'll be hitting 75+ as I'll be getting other trace amounts of carbs from nuts, veggies, etc.

Does this sound like a good plan?
