It depends on how quick. Exercise (cardio) and diet ( 3 meals a day that include fruits and vegetables and healthy snacks). Also, cut back on your portions. Park in the last/end parking place and always take the stairs instead of the elevator or escalator. Swimming is one of the best exercises. Good Luck!
Remember to love your body. Remember only inner beauty counts. But i go to the YMCA to work out, do the tread mill, yoga, running and walking are the best. If you drink pop lay off of it. In one year of me drinking pop i gained 100 lbs, yes that is alot. But hope this helps. And one more thing don't eat anything WHITE.....
Eat healthy and do a good amount of exercise and if that doesn't help have your thyroid checked it may sound crazy but if you have a thyroid problem it slows down your metabolism and makes it hard to loose weight.
The 3day lose 10lbs military diet works. It's not that bad ethier u do eat real food I have done this and many friends too with proven results. But this is just a kick start..u need to do cardio and watch what your putting in your mouth. Oh and drink lots of water!!!
