What works for me (and may not work for anyone else) is choosing a weight and bodyfat goal. Then multiply that goal weight times 10 (180 x 10 = 1800) and eat that many calories per day until you reach your bodyfat goal. Once you have met your bodyfat goal, slowly increase your caloric intake with protein to build/keep muscle. If your bodyfat goes up again, drop the calories down a bit.
You could try 12 x your goal weight to see if that's enough.
Focus on lean protein, lots of veggies and complex carbs. Don't fill up on carbs. Fill up on protein and veggies and toss in a few complex high-fiber carbs.
Drink lots of water or green tea (good iced).
Unless you supplement with (insert anabolic here) you will lose some strength as you lose weight and bodyfat. Focus more on quality lifting (form and technique) instead of quanity lifting (weight and reps).
Are you taking synthroid?
