Self-control isn't something you "just have" (or don't have), it's a part of a complex set of behaviors that are learned, practiced, and contingent on many factors. I do agree, though, that it's a big part of successful long-term weight control. Inasmuch as "self control" as a very broad generalization is useful to begin with; it's probably reasonable terminology, if you approach it critically.
Nutritional choice-making and behavioral modification go hand in hand. That's why nutritionist will not only tell you to eat healthier foods, but also to modify HOW you eat - at what time, in what setting, etc. Not because that dramatically changes the calorie count (there's some minor effects due to metabolic factors but they're often vastly overstated) but because certain behaviors are more - or less! - conducive to maintaining a good diet in the long term. For example, spreading out meals across the day rather than having a single big meal will often result in very similar overall calorie intake, but will make coping with cravings easier and lessen the risk of "cheating" on a diet (assuming there aren't other medical reasons at play, of course, like controlling blood sugar levels for diabetics etc.). Similarly, preparing meals by hand rather than buying processed or ready-to-eat meals can be conducive to healthier diet because it trains you to watch what you eat, making it more likely that you eat healthier food. And so on.
As always, though, there is no magic bullet. A good diet and maintaining a healthy weight and exercise is a complex and highly subjective process. It doesn't necessarily take backbreaking work, but it takes a lot of care about many little interconnected things, with results that usually won't be immediate or easily reduced to simple causes. The key is long-term care - the goal should be to both reach a target weight/body and MAINTAIN IT. Losing 50 pounds to heavy dieting over 2 months is worth very little if you put those 50 pounds back on again another 2 months later because you slipped on your overly stringent diet. It may be a better idea to lose 50 pounds over 6 months instead, but arrive at a place where you have changed your behaviors - slowly but steadily - to a point where you'll keep those 50 pounds off for the next 50 years, too.
