I have gone through your concern. Being an Ayurvedist I would recommend you a diet chart along with some tips which you can add in your lifestyle and enjoy the change.
Tip 1. Take 10-15 gms of coriander leaves with its stalk. Wash it properly. Now grind it to paste in your mixer by adding little water to it. Consume this paste every morning empty stomach. After half an hour you can have your tea or water....whatever you want to have.
Tip 2. Take atleast 2-3 cups of green tea. If your get green tea without caffeine...that would be the best.
Tip 3. Do some exercise(ask your gym trainer) daily or Do a normal walk daily for 30-45 mins.
Tip 4. Always take fresh food and fruits. Keep canned fruits or foods, fried foods, precooked foods at bay..
