What are some of the most effective ways to lose weight?

Well it depends on what kind of situation you are in, but a good regular diet is to go outside once a day and walk,jog,run,etc. Do not i repeat not skip meals!
eat breakfast lunch and dinner, and you have to be able to know your proportion sizes , remember to walk everyday it will help do some sit ups and push ups too
well i hope this helped:) if you have got any questions ask:)

The most effective way to lose weight is to have a moderate workout at least 3-4 days a week. During each workout or exercise you should have an accelerated heart rate for 20-30 mins. A healthy diet concluding protein.
