Does intermittent fasting lose effectiveness overtime?

I've been intermittent fasting for over a year at this point. I don't really see the effects that it's supposed to have anymore. (16/8 method)Does your body just naturally adjust to the schedule and your metabolism returns to normal after doing it for a while? Like the way our body becomes immune to caffeine, you can also become immune to the health benefits of intermittent fasting?Could someone who understand the science of it please explain if this is possible. via /r/intermittentfasting https://ift.tt/2FEP7hZ https://ift.tt/eA8V8J
