Just a quick question.

Without removing parts of your body, like arms or legs this is NOT possible and medically inadvisable.

Put your jeans in the wash without checking the pockets.

Oh, you meant 50 pounds in weight? Give birth to triplets. Apart from that, it's really not possible or healthy.

To lose a pound of fat, you need a calorie deficit of 3500 calories. To lose 50lb in 30 days, you'd need a calorie deficit of 5833 calories a day, so even if you eat nothing at all, you'd still have to run a marathon every day to rack up that deficit.
