Without looking at your diet record it's hard to make any recommendations really. There are many ways to reduce weight and I always start with the saying..."Eat like a king in the morning, like a prince at midday, and like a pauper in the evening".
1. Stay away from saturated fatty foods and increase intake of fats from fish and olive oil.
2. Consume more green veggies/salad stuffs and reduce white foods: pasta, potatoes, rice, and white bread.
3. Eat egg whites but not much yolks (if you have high LDL cholesterol stay away from eggs if you like).
4. Lower your salt intake, because it increases blood pressure and makes your body hold onto water.
5. Take one mulitvitamin/mineral supplement a day.
6. Drink plenty of fluids. This also makes you feel fuller at mealtimes, meaning you don't eat as much.
Basically, you should not reduce your calorie intake any more than the 2000 at present. Like Zygla says, if you do your body will hold on to the fat you already have
as it will be in a starvation mode. Best thing is eat all your calories from low fat green sources and white meats. There is a lot of food to 2k kcalories when eaten from
lowfat/high nutrition sources than if you just ate junk, and I promise you will feel fuller too.
Do that and increase your waking hours (if you sleep more than 9 hours a day) and increase frequency, intensity, and duration of your cardio workouts.
I'm assuming you're a reasonably fit guy who is medically cleared for exertive exercise?
Good food/plentiful exercise=weight loss while maintaining FFM.
