large-scale fraud
Refers to a weight-loss rip-off where they photograph da joyfully-beaming "satisfied customer" standing on an oversized weighing-machine dat merely makes him LOOK smaller/slimmer because said machine is itself so much bigger than a normal unit would be --- it's all merely a matter of perspective, like when they used bigger-than-normal set-pieces when filming da early-teenage Macaulay Culkin because he had grown so tall at such a young age.
Large-scale fraud aside, another simple way of faking weight-loss results is to use an **earlier** photo of da still-somewhat-slim-at-da-time person (i.e., BEFORE he even STARTED da weight-loss program!) as da "after" photo, and then showing a **later** photo of da person and falsely labeling it as a "before" photo --- i.e., showing da person in his **present** tubby bloated status dat he ballooned up to **after** starting da calorie-filled quackery-diet, and falsely claiming dat it's da "before" photo! Disgraceful!!
