It's dead simple as long as you enjoy feeling hungry and irritable all day, have a magical body that burns the same amount of energy regardless of food input, and don't mind losing a ton of muscle mass during your diet.
The real answer is to cut out most of the carbohydrates that you eat (or at least lose the grains, there's some debate about potatoes and such) and replace them with fats instead. After a brief adaptation period, you can just eat when you're hungry and, because fat is more satiating, you'll naturally consume only what you need. Because you're not shoving tons of sugar down your throat, you won't experience the insulin surge-crash cycle, you'll have more energy and be less hungry than you would on a traditional "diet". Because you're eating more protein you'll lose less muscle mass than you would on a typical weight loss diet.
It might seem "extreme" or "fad" at first, but there's a growing body of evidence that suggests cutting carb intake is actually a very healthy and sustainable long-term choice. I do it and I recommend it to everyone who is looking to make a long-term diet adjustment.
