Diet is very important if you want to lose weight.
Cut down on your carbs, especially white rice and white bread.
And avoid having late dinner (after 8:30pm) as well as supper.
As for exercise, aim to do cardio at least 3 - 4 times a week.
Minimum 30 minutes per session. You can try running, swimming or go
for spinning classes. On top of that, do some weights if you can as
you burn more while resting from weight training.
