Brief Answer:
lifestyle modifications, exercise and diet management...

Detailed Answer:
Hello XXXXXXX Welcome to HealthcareMagic,
I've gone through your query and understand your concern,

The first and foremost step to consider is diet management, I'm giving you a brief idea about it below, however, for a complete diet-chart, you can request for a Diet-Plan by the Dietitians(check for the option for Diet-plan in your package, and do mention your body weight, height, diet preferences etc, to the dietitian while requesting for this)...

Avoid junk foods in any forms... no excessive deep fried/ fast foods strictly...

Include fresh green leafy vegetables in your daily diet.. have a bowl of salad every day...avoid processed and packaged foods, always try to eat fresh, organic foods, have fresh fruits instead of packaged fruit juices...try to include high amount of antioxidant containing foods like olive oil, beans, and legumes, whole grains, plenty of nuts etc...

- Try to snack healthy instead of junk foods, have a handful of high zinc & antioxidant containing foods eg. cashew, almonds, raisins, pistachio, dry roasted/boiled chickpeas, yoghurt daily...

- Drink plenty of water throughout the day(at least 2.5 ltr) to remain well hydrated and it'll help to flush out the toxins and metabolites too...

Along with this, 30-45 min of daily workouts, free hand exercises, jogging in the park, to be done as an initial step, which later on can be stepped up to active work-outs in the Gym under proper supervision of the physical trainers...

These are the best, and absolute way to gain proper body shape (including tummy), body shapers are not recommended for this purpose as the natural way is the best for long-term well-being...

Take Care
Kind Regards
