oxygen. Please go for a walk twice a day. Let this walks be within half an hour of sunrise and one hour before sunset. You should walk for minimum 40 minutes at a stretch with 90 steps per minute.

proteins. Avoid nibbling. Have small feeds every three hours. Avoid maida, sugar, vegetable hyderogenated fats like Dalda, etc.
