Some people are so obsessed with counting calories and push themselves in an extreme level. But just after a couple of days, they start eating like they used to before. And they don't get the result at the end.
Setting up small goal seems easy. And if there is a reward like ice cream for ice cream lovers, that will definitely motivate more :)
On behalf of all ice cream lovers, thank you so much @gflfitness for your valuable suggestion! :)
