Sometimes the most effective ways is the simplest.
I think this applies to losing weight, for one, after reading complicated techniques, it will only confuse the mind or it becomes so difficult to implement that you will give up in no time.
Below are simple ways which you can do right away and make it a habit.
Simple strategies to help you with losing weight:

1. Say No to soft drinks - give away all the cokes in your fridge and any other can drinks that you have there.
   Replace them with water.
   Hmmm..
   ..
   sounds difficult? A tip to help - paste the poster or picture of your dream body at the fridge door.
   Another tip is to drink with a slice of lemon.
   Try this out!
2. Change to a smaller plate / bowl - whatever that you use to when eating.
   No joke, this is just a small twist but it makes a different.
   You can't take in that much in a smaller plate and you know what? Before you know it you are eating less..
   ...
   yep, if you feel like you can reduce further, keep changing to a smaller plate.
   The trick is not to do it drastically else you may rebel.
   Go slowly, just a little smaller - when you are comfortable, then change again.
   
3. Substitute junk foods with nuts or salad like baby carrots or celery sticks to bite on.
   Yeah, I know you grow up with potato chips and what's a movie or good TV program without those.
   It's important that you keep your mouth busy, that's why you need substitute.
   I'd say having fruits or vegetables or nuts will be a great fit.
   
4. Stand up and do walking on the spot when watching tv or if you have a treadmill and gym bicycle, it's time to move them over to the living room and move your sofa out.
   Instead on watching the soap opera on your sofa, do some walking or exercising.
   In no time you'll be burning fat and without realizing it you are losing weight.
   
5. Can you spare 10 minutes for walking? Just add 10 minutes of evening walk and 10 minutes of morning walk around the block.
   Hey, I know what's on your mind, 10 minutes will not do any good..
   ..
   nope it starts with 10 minutes.
   You have to build consistency.
   One of the top reasons why people fail in losing weight is because they set very high goals like from nothing to jogging 2 hours a day.
   Seriously that's the path to failure for the simple reason it's creating a "shock" to your normal behaviour.
   After a few days you'll give up because it is TOO hard.
   

Remember the race between the rabbit and the tortoise? Consistency and persistence wins.
The thing with all the above tips is it appear to be simple - that's why it works.
Try out and I bet after you achieve that you'll crave for more...
which is great.
Boost your confidence that you can do this and you'll be internally motivated to walk 5 min more or eat a scoop less...
and the great news is you'll find your dress size keep dropping without you feeling the pinch - in your lifestyle as well as in your pockets.
