To lose 15 pounds in 1 month about 4 pounds a week how can you do that?

Snack every 3 hours on protein (it feeds muscles and will therefore speed up your metabolism which will burn fat faster). At meals, with every vegetable serve have protein too. Drink 4+ litres of water a day, as it is suspected to speed the metabolism slightly and also cleanses your insides. I suggest taking metamucil or a fibre supplement to get rid of any toxins/waste.

Weight train 3-4 times a week (this tones muscles which burn fat and will not make you look muscly- just toned- unless you're a male), do cardio such as bike riding, walking/running and develop a daily routine such as the stairs instead of the escalator or lift.

You could have one 'free day' and eat whatever you want, but you must get back to eating healthily the next day.

This has helped me lose 10kg in about two months, which I believe is the equivalent to 22 pounds. It is a healthy choice and something that is easy to follow. !
