Avoid heavy, salty food as it promotes water retention and bloating. It is better to have medium to low salt food.
Start body massages once a week with a light oil like olive oil. Massages promote the lymph channels movement which not only aids to decrease the bloating but also assists weight loss by improving the bile flow.
Eat light foods like vegetables, fruits, cereals etc and avoid too much of meat or fish. One can also enjoy grilled, tandoori foods which need minimum oil/butter.
Avoid fried foods as they decrease the digestive efficiency.
Do not indulge in heavy exercises, instead walking along with yoga or stretching is better as heavy exercises cause an increase in body temperature which leads to headaches, body aches etc.
