When you crave for a tub of rich chocolate ice cream, you can blame your hard wired ancestral genes for it. This is the truth about evolution. Our ancestors had access to limited sweets, the only one being ripe fruit. So on a lucky day when they’d spot a fig tree, they’d eat as much to their hearts content. This super strong craving gene is still in our DNA. So, even with an overstuffed fridge of goodies, you still want to wallop down the whole tub of creamy ice cream, you now know where is that craving wala feeling coming from!!!!
