A personal trainer whose blog is dedicated to "droppin' truth bombs" on the lies told by the fitness industry has uploaded a rather remarkable example to her personal Instagram account.

Promising a foolproof method of "losing 15 pounds in 15 minutes," Mel of MelVFitness reveals that many "before & after" photos seen in ads for weight loss suplements are actually optical illusions.

She explains:

Check out my transformation! It took me 15 minutes. Wanna know my secret? Well firstly I ditched the phonewallet (fwallet) cause that shit is lame, swapped my bather bottoms to black (cause they're a size bigger & black is slimming), Smothered on some fake tan, clipped in my hair extensions, stood up a bit taller, sucked in my guts, popped my hip- threw in a skinny arm, stood a bit wider #boxgap, pulled my shoulders back and added a bit of a cheeky/Im so proud of my results smile. Zoomed in on the before pic- zoomed out on the after & added a filter. Cause filters make everything awesome.

What's my point? Don't be deceived by what you see in magazines & on Instagram. You never see the dozens of other pics they took that wernt as flattering. Photoshop can make a pig look hotter then Beyonce.

A complete breakdown of the steps, including Mel's personal "transformation" testimonial, is up on her blog.
