Prediction or coincidence(11/365)

Either Google is very good with prediction or has a good spying ability or it's just a coincidence.
Today is day 2 of me not consuming any processed sugar. It was just a causal discussion with my dad on obesity and weight loss and from the next day Google recommended '30 days without sugar' video on my YouTube timeline. I didn't search sugar or weight loss anywhere on google. And yet it was recommended.
But I am not complaining , the recommendation actually motivated me to take the leap to not have any processed sugar.
This means no waffles, no soft drinks, no burgers or pizzas and anything which is packaged. Really difficult if you are a bachelor like me who has no idea how to cook.
So first day was ok, second day I just started to feel hungry all the time but my energy levels stayed up which seems good. Let's see how it goes in the next few days.
Coming back to prediction, i am still not sure what caused Google to recommend the exact topic which I discussed and was nowhere searched or accessed over the internet. Or maybe it's just a trend here in my age group in India which is why it showed up.
