Reduce calories until you are losing 1-2lbs / week
Foods for satiety: anything high in fibre and protien: salads, beans, lean meat, wholegrain bread, boiled potatos etc.
Make sure you get AT LEAST 1gramme of protien per lb of bodyweight per day
Do 3 x weight workouts per week with big compound exercises. You must include squat and deadlift in this. High reps don't do anything special by the way.
Fill in any remaining workout time with cardio. Elliptical machines burn off lots of calories / hour. You can also look up HIIT.
