Welcome to HealthCare Magic,
Thanks for your query.
It seems to be the problem related with imbalanced diet rather than the problem of over eating.
Better you avoid all fatty foods,fried foods,sweets etc.
Kindly consult a Nutritionist to check your food type and advice for the balanced nutritional diet.

Kapal Bhatee Pranayama is most preferable exercise for you.
