It’s pretty glib to just reduce the idea of intermittent fasting to “you don’t eat.” Intermittent fasting shouldn’t even be seen as some kind of innovation, since it’s essentially a return to how human beings have managed their metabolic processes for tens of thousands of years.
It’s actually the idea of eating all day everyday that’s the innovation. We evolved to be hunter-gatherers; we had to chase down and kill animals for sustenance, and there was no reliable way to preserve that food. Which means that we are adapted to eating once or twice during a day, probably during the daytime, when our bodies are meant to be active, and then abstaining from food. It’s the relatively recent innovations that changed the way we handle our metabolic processes, like having food available all day and filling it with sugar, that are responsible for the proliferation of things like obesity and diabetes, which our ancient ancestor just didn’t have to deal with to the extent that we do, because their diets were more “natural” and less maladaptive compared to ours.
All this is to say that when we’re talking about our diets from a normative point of view, we should think of intermittent fasting sort of as the null hypothesis, necessitating a rebuttal before it can be refuted, and our modern way of stuffing our faces all the time as the alternative hypothesis, requiring justification before it can be accepted.
For a healthy adult it’s probably more sensible to consume one’s diet within a reasonable window, say 8 hours per day, than to be constantly digesting the hyper processed, over sugared nonsense we put into our bodies nowadays, to the point where it overlaps with things like our sleep cycle and when we get our exercise in.
Of course, I’m not a physician, so don’t take my word for it. But you should consider the fact that formal research is increasingly coming to understand the benefits of IF; OP’s link is only one example. We don’t understand the full range of benefits that IF provides because modern medicine, in the grand scheme of things, is still pretty much in its infancy; we’ve existed for approximately 200,000 years, but we’ve only had modern antibiotics for less than 100. But it can’t be denied that so far, things are looking pretty good for intermittent fasting, at least when it comes to its suitability for “healthy” adults.
I am an intermittent faster as well and IF got my blood pressure back to normal after 17 years of medication.
But I have my doubts regarding usefulness of IF against dementias. These are strange, autodestructive diseases. Maybe IF can lower their incidence or push them to higher age, but unlike diabetes 2nd type, I cannot believe it can reverse them.
I think it is more like avoiding large amount of carbs to avoid developing type 2 diabetes. IF, low carb diets and more all contribute to helping avoid damage. I've even heard of Alzheimer's being called 'type 3 diabetes'. Also looking at the victim, he didn't look to be metabolically healthy, along with his wife. Households tend to eat similar.
Also not eating for 4 hours before you sleep and after you wake up is a very low risk, cheap & safe thing to try out compared to many other things. Same with avoid cheap carby things and eating more meat, eggs, vegetables and more non-processed carby foods.
> Also not eating for 4 hours before you sleep and after you wake up
Wait, does that count as IF? I mean yeah, I guess it is called break-fast, but does sleep time count as fasting time? Somehow in my mind it felt like it would "pause" the clock.
Yes they have carbs, but usually not to the amount and density that most pure, cheap carby foods like rice, potatoes, yams, bread, etc tend to have. Vegetables also have higher satiation.
It's actually fairly hard to get enough protein with a vegan diet unless you're eating beans, soy and vegetable protein extract and it's easy to fall into eating a lot of carbs and vegetable oil with some vegetables for flavor.
Yeah definitely, I wasn’t trying to claim it was some sort of panacea. I’d be surprised too if it helped cure something like Alzheimer’s.
Still, we’re learning surprising things about how our bodies work every day, and how seemingly unrelated parts are actually very interdependent. For example, we’re now seeing that the bacteria in our guts, our microbiome there, has a range of ways it maintains our health beyond just serving our digestive tracts.
