I’m basically behind this article and agree the books sound too clickbaited. But two points —
The fat-phobia era did make a lot of food less savory. That the sugar industry was behind propaganda is a damned big story — simply because they knew fat-free remakes would require added sugar to taste decent at all. And checking on added sugar is well worthwhile (pretty easy to tell if it’s outta control).
Next, I think the common-sense council at the end of the essay is undeniable, but also not enough. For years and years I read similar advice, knew I was trying to be as common-sensical as I could and remained 30+ pounds overweight.
I would advise a visit or three with a pro nutritionist (now, thing is, I know they are like physical therapists — not all created equal or right for everybody; the one for you is the one where you get serious results following the advice). I found some fundamental things I considered common sense were not — e.g., pure OJ is a harmless thirst-quencher; intense exercise, as much as you can manage, is what will keep the weight off. And some essential affirmations: keep getting on those scales every week, dammit! Nothing becomes automatic — you will have to be mindful about your eating for the rest of your life. It is way too easy to chow too much when you work down the hall from your kitchen.
