Not seen any, and wouldn't expect to TBH. Clinical trials with interventions look for measurable results in short timescales as the costs and dropout rates are too high on prolonged dieting.
There's published data on 6 month diets with 25% calorie reduction but I haven't seen a sort of phased approach as you describe.
A fat-phobic diet does condemn you to elevated insulin levels and decreased lipolysis I suspect.
