So, I actually used Isagenix. So, OP, here’s the what:
It’s lousy. Does it work? Maybe sorta: if you follow it religiously, you’d be reducing calories unless you already eat like a bird. So you’d probably lose weight. Following the plan, however, is incredibly difficult, because the products are seriously unpleasant.
As everybody on here is pointing out, “detox” is marketing woo, so let’s ignore that whole part.
Why did I try it? Simple. My mom got wooed by a friend who became a seller and bought a bunch of the supplies. She, like moms do, casually offered me a bunch of this amazing new diet product. I, like a broke guy in my 20s might do, figured, “hey, free sorta food.”
Nope. The program elements are lousy.
The big centerpiece is the “juice cleanse” stuff. It tastes like spoiled cran-apple juice with an uncomfortable chemical aftertaste. Vaguely medicinal and slightly oily. It’s full of aloe vera gel, which is a laxative. You connect the dots.
During the cleanse, you also get to eat brown chalk lumps, err, “chocolate snacks.” If these were originally manufactured as dog treats and repurposed when somebody realized the cocoa powder was killing dogs, I wouldn’t be surprised. Just awful.
There’s also meal replacement shakes. These aren’t exactly terrible. They’re just seriously overpriced and taste worse than SlimFast or generic protein shakes.
And then there’s the meal replacement bars. I actually kinda liked these. They’re an easy grab and go breakfast, and some of the flavors were okay. They are, however, basically just hyper-dense candy bars and I’m sure no better / cheaper / healthier than something like a Cliff bar.
So…don’t bother. It’s overpriced, mediocre, and extremely, extremely artificial and processed tasting. Unless you’re one of those people who literally can’t tell foods apart and just want some slight variations the texture of your nutrient pastes, you’ll find it unpleasant at best.
