I think a lot of people have pretty bad misconceptions about diets in general. You might think dieting is about "eating 6 times a day, egg whites for bfast, chicken breasts throughout the day with a cup of rice and some broc on the side." Honestly, everyone diets, and you can either have something along the lines of a clean, structured diet, or an unclean, unstructured diet.
The difference between the 2 (or 4, really) is that at one end of the spectrum you eat healthy foods, and/or you count your calories -either literally with a log, or you ballpark it within maybe 5%. So from day to day, there's some sort of regularity in your food intake, you are hitting some sort of calorie or macro goals, and you are eating foods that are nutritious. Of course this is not to say your diet is necessarily healthy from a holistic sense since eating only chicken, eggs, bananas, broccoli, and rice is nowhere near a well-rounded diet, but you're not eating lots of foods that have empty calories or lots of sugar (fried foods, candy bars, etc).
At the other end, you don't count your calories, and/or you don’t watch what foods you eat. So maybe you skip some meals, eat a few candy or protein bars here and there, a dinner maybe, cereal for breakfast, etc. Most people fall into this category. They don’t care what they eat in a meal, or what they eat throughout the day.
I think in the end you are very driven to fall in the first category. Beyond following the steps I laid out, the differences are small and are based on your preferences and lifestyle. Start at the top, just watching what you eat and trying to eat with some regularity and you'll be fine. This can mean just throwing together some sort of mega-protein shake for breakfast (protein powder, fruits, peanut butter or EVOO or EVCO, etc), preparing a chicken salad or something for work, and eating some meat and veggies for dinner, eat some almonds over a snickers bar ... whatever, but the point is to not needlessly obsess over the details. But do take care of your health!
