What has been working for me (I've lost 8kg in 4 months) is Weight Watchers - not the meetings, just access to their points-rated food database via Web and App, which makes keeping track of your points budget reasonably convenient. The biggest advantage is that you don't have to make any fundamental changes to your diet or habits and it's flexible enough to accommodate occasional big, unhealthy meals - so there's not too much self control necessary to stick with it. It also subtly pushes you towards eating fruit and veggies because most of those have no points and thus can be eaten at any time, as much as you want.
