Kind of the other extreme - "eat as much as you want and NOT GET FAT"… if you eat more fat than you burn, your body will store some of the excess fat, no matter what kind of diet you are on. The extent and locations of fat storage are somewhat genetically determined. Fat is essential for life.
People seem to be deaf to the notion that getting exercise and try to eat a wide variety of fresh, unprocessed foods is probably the best thing you can do to stay healthy. Forget about the Atkins diet, the South Beach Diet, the Paleo diet, the California watermelon diet … they all come and go but the 2 basic principles (exercise and sensible eating) always hold.
For me the big takeaway from that article was the arbitrary basis on which the whole notion of 'fat makes you fat' came into being and subsequently became common wisdom. Confirmation bias and a desire for a convenient and comfortable solution.
I grew up in the middle of this stuff. Low-fat everything, artificial sweeteners, pasta (because pasta and bread are wholesome - they can't make you fat!), egg white omelettes and carbo loading (anyone remember that??). Then we went a bit too far in the other direction with Atkins and ketosis. Now we're landing somewhere in the middle, trying to avoid industrial food stuff, processed carbs and crappy meat in favour of organic/hormone-free whole foods with an emphasis on locally produced everything.
We're getting better.
There's nothing better than an Orangina after cheating death with Digger.
