Many people who try to lose weight are very impatient to see results quickly. But you've got to remember, it probably took you a long time to put on those pounds, so it may be take awhile to take them off too.
Why not start building certain things into your lifestyle on a gradual basis, things that you can maintain for the rest of your lfie without feeling "deprived." Like parking further away from your office so you can walk more. Daily walks of at least 20 minutes.
Replacing unhealthy snacks, processed foods and soda for healthy snacks like fresh fruit and vegetables.
If you find yourself eating most when you're in front of the TV at night, try turning the TV off and doing something else; pick up the phone and call an old friend, start cleaning out that junk drawer or develop a new hobby.
