What type of exercise do you do? When you look at the weight loss research, it suggests 1200-1500 calories each day for long term fat loss. They key, though, is not just calories that matter but the quality of these calories - a carbohydrate can be a can of soda or an apple, for example. So focus on high fiber carbohydrates (fruits, veggies, grains), lean proteins, and healthy fats.
