When I first attempted to lose fat (and I still do this NOW) I used ‘Guerrilla Cardio’ (GC) (Kennedy, 2001): This is tabata intervals done sprinting (instead of on a bike). You jog lightly for 4 minutes as a ‘warm-up’; then you do 8 x 20 seconds hard-out-as-fast-as-you-can sprints/efforts, and jog easy for 10 seconds after each one; finishing with a 4 minutes easy jog ‘cool-down’. I do GC (or variations of it; now I increase how many efforts I do, and sometimes do up to 3 days a week, with a rest day between each one, as it is very hard and takes a lot out of you. If you do this, and you are doing weights and eating to lose fat, then you will most definitely see results.
