18in4 = quick fix = waste of time and money
No really.
This particular diet and many others almost identical in their promises and astounding "real life" testimonials all pretty much add up to the same thing...
A big steaming load of poop.
Do a search for 18in4 and you will see many here tried it, most I read about did in fact lose a fair bit of weight, but the discomfort wasn't worth it and they gained it all back.
I can offer you the same diet for free.
1: Desperately under-eat for a few days and try to load up on low cal or no cal liquids to help the hunger pains. (wont work, but you can try)
2: Revel in the water weight you lose over those 4 days, hopping on the scale frequently. Go Team!
3: Sob quietly to yourself the week after when all that water weight has miraculously come back and you binge right back to where you were before (or bigger)
Only real positive thing I could see coming from all these quick fix schemes and dreams is maybe, just maybe, it will make you angry enough and pissed off enough to give you energy to throw into a healthier plan, which though perhaps slower, has more real, and sustainable goals.... If you can use that anger to fuel your desire to make a real difference, well worth the 27 bucks.
That said, if you REALLY want to throw the money away, please follow my plan and give the money to me!!!! All donations will be happily accepted and put towards my "new skinny clothes fund"
Better yet, stick that 27 bucks with a magnet to your fridge and think about the bathing suit or sexy outfit it will help to buy when you reach your goal the hard way....
