Watch your portions
Don't snack on cast-offs foods
Drink LOTS of water, when you get up up, before bed, and throughout the afternoon... gets your metabolism going
Avoid fried foods
Add some cardio to your each day routine
no matter what, exercise is the push button to losing weight. as vanessa williams said, "you hold to work it to earn it." there is no effortless way to lose solidity.
do aerobics.just avoid consumption fried food and start walking or jogging.
To loose immensity eat healthie stuff. exercise. no second-hand goods food. and drink water no soda. do a work out everyday this should oblige
