Consistency in your workouts.
Progressive overload in your weight lifting: keep increasing those weights gradually and push yourself when it starts getting easy. Weight training needs to have more prominence in your weekly workouts now than cardio to make a difference in your body. Lift heavy. Start with total body workouts, progress to 3 day splits, then daily training of a separate body part, if that suits you. Change up your lifting program every 3 months or so.
Regular cardio workouts, 3 or 4 per week, 45-60 min sessions, including 1 or 2 interval type workouts.
Clean up your diet. Jettison the cakes, sweets and pastries. Eat hearty carbs, good doses of protein and fill up on veggies and fruit.
Patience. Change does not happen over night.
