The easiest thing to do to reduce your caloric intake is to start cooking...it's very hard to get to high calorie numbers if you are making your own food instead of eating out.
Oh, and when you're hungry eat a meal first then snack later. Don't start snacking first or you can find yourself over indulging in chips to make up for the meal you didn't eat on time.
Cooking your own food is a great way to improve your health and also unplug from technology for a while. Restaurant food is usually way too full of oil, sugar and salt.
Another very healthy way to reduce your caloric intake is to make fresh vegetables the center of your diet and then fill in from there instead of eating the occasional side salad.
When I started to cook I actually gained a huge amount of weight. I've no idea what you mean by being hard to get high calorie numbers. It's as easy as any other way: you eat too much food. It was only when I actually learnt what a sensible serving size was and actually weighing out my ingredients (especially carbs) that I became normal again.
Usually I just throw some meat on the grill and put it in a quesadilla or sandwich with various toppings. I occasionally make a salad, but very very occasionally.
I feel pretty full and rarely take in more than 2k calories a day - I'm not limiting intake in any way.
I've never struggled with weight though, just a few pounds after college prompted me to start cooking.
