Before/after weight loss photos

I just HAD to share this with you - it's one of those before/after shots which are used to sell various types of weight loss and/or fitness products:

As you'll see, not only does the advert show what (at least to me) seems like an unrealistic amount of weight loss/muscle gain in only 30 days, but also the program appears to make you lose your body hair and get a tan! If only!
I actually went to the website, and they are using the same two photos but claim the results take 49 days...
These photos are clearly cause for concern. And obviously these are not the only weight loss/muscle gain people to use before/after photos in which the 'after' photo has better lighting, better posing, fake tan etc. And that's not questioning whether the results were achieved in the time stated and using (just) the products advertised or not.
Anyway, as I'm currently pursuing the turbulence training bodyweight program, I thought it made sense to take a 'before' shot for two reasons. One is to give me something to compare to as (hopefully) my body composition changes. And the other is to give you a real before/after comparison.
I'm really looking forward to taking the 'after' photo - perhaps in 3 months or so?
