Just wondering how some of you would address an issue I'm having with leading my wife to lose some weight. A little about me; former powerlifter, always been in good shape but after an injury that ended my involvement in the sport I gained a decent amount of weight, started moping, turned into a bitch a bit. Got my shit back together about 6 months ago, have been cutting fat and started lifting again (more geared towards general fitness than pure strength so doc says OK) and there has been a noticeable difference in my relationship with the wife, as she's starting to have her man back again. During the downtime when I let myself blob out, she kinda did the same thing and gained some weight herself. Now that I'm owning my shit and leading again she's also back to exercising, zumba classes etc.
The problem is with her eating habits. As someone who's been a gym rat most of my life I know that CICO (calories in - calories out) is the most important thing when it comes to dropping the weight. My wife on the other hand is one of these women who gets sucked into bullshit fads, magic weight loss pills, doctor Oz horseshit and whatnot. So she'll go for an hour long run, come home and immediately smash a bunch of chips or something, and then take some thermogenics pill/powder and think she's on the right track. Leading through action has worked in terms of getting her active, but doesn't seem to be sinking in when it comes to this. I've tried broaching the subject with her a couple times, and it gets met with a defensive attitude...I feel like trying to educate her directly is having the opposite effect that it should. I'm concerned that after some time has passed and she's made no progress on the scale she might get frustrated and give up.
How do you guys think this would be best handled? Should I just stay the course and hope she learns through experience (and failure) that there is no magic bullet for weight loss? Is there something more I can be doing to lead her in the right direction?
