You need to wait 12-24 months before you can consider your diet a success.
A caloric deficit doesn't work long term, as over time your metabolism slows down to match the caloric intake.
"The key to long-lasting weight control is to control the main hormone responsible, which is insulin. Controlling insulin requires a change in our diet, which is composed of two factors — how high the insulin levels are after meals, and how long they persist. This boils down to two simple factors:
What we eat — which determines how high insulin spikes; and
When we eat — which determines how persistent insulin is."
