Dont worry about looking like a wwf wrestler, believe me you'd need to be doing some seriously heavy weights, eating at least 100grms of quality protein every 2-3 hours and doing some serious heavy cycles of ahem, 'additional supplements'.
As a general rule of thumb work out your ideal weight in pounds. You want to be consuming 1 gram of protein for every pound, so if you want to be 150lbs you needs about 150grams of quality protein. For a good balanced diet Id go for 40% protein, 40% carbs and 20% good fats. When you stop losing weight play around with the carbs/fats. People have a downer on fats but your body uses fats for most of its energy. Egg whites, flax seed oil, olive oil, fish etc all contain excellent fats.
Split your meals up over the day, its much better to eat little and often, this will keep the metabo fired up. Eat the most carbs in the morning and taper them off over the day. Drink alot of water and exercise, espec with weights. Oh, and tons of greens, the more the better. If its white dont eat it is another rule that you can use, and substiture potatoes for yams, sweet potatoes etc if you eat alot of them.
Sadly I lost all motivation long ago but a few years back I was in seriously good condition. I had a body weight of around 14 stone with fat % in the high single figures. To MAINTAIN this I was eating around 7 meals a day and needed about 400 grams of protein. Thats alot of eggs, chicken, tuna, whey protein and salmon every day. Its a shame I dont take my own advice really.
Another excellent way of burning those fatty deposits is to do CV first thing in the morning before you eat anything. Work out your max heart rate and maintain 70% of this for 15-20 minutes, this is far more effective than doing CV at any other time.
