There are only so many body types and drug combinations one can be on. Making a diet isn't rocket science, but the trainers will make like it's a custom custom tailored event.
"Yeah, you look good, but let's bring down your sodium and cut some carbs. Yes...yams are what we'll do this week. Send me a photo next week and I'll see how you're lookin' bro. I may put you back on rice and slurpees, but it may be potatoes. I'll have your body so confused....it will be a fat burning furnace!!! Oh yeah, send that payment to my paypal too so we're square for next month. Bro honestly, this show is yours to lose! Keep on it. I believe in you."

It's all about stroking the ego and given the bber the allusion of having that edge.
