I think it's just a little scary for people. There is the old saying, "If it ain't broke, don't fix it!" After losing close to 50 lbs on the old plan, it is scary because what if this doesn't work? But hey! I'm giving it a shot
The other thing that is weird is how pretty much everyone has 29 points - it doesn't make sense to me, but I guess they know what they are doing.
My other worry about this plan is that I am eating MORE on it. I used to eat around 4 or 5 points a day of fruit... I wouldn't use points for 100 calorie packs, or cakes, or fast food, or the other stuff they are trying to steer people away from...
But like I said, I'm definitely giving it a shot for 2 months just to see how it goes.
