the apple group consumed 120 more cals per day at 12 months compared to baseline while the plum group consumed 200 more cals per day compared to baseline. Yet, the apple group lost weight...hmmmm...sounds dodgy...

It sounds like the dieters didn't log their actual intake but instead an RD analyzed a sample week at 4 time points. I don't think that is going to be much use, not with a 120 calorie variance, anyway. And I wonder if "recall" means they went from memory for the prior week? That would be even worse.

I was thinking that too. Even if they did a log week to week it's well known isn't it that intake can be under reported or the opposite too I'm assuming.
