It totally depends on your weight..moreover everyone is beautiful in their own way.! In their own body a person just needs to feel confident!
It variees from person to person. You will not see results overnight. However if you keep consistent and watch your eating habits you see a change in 1 or two months. Now if you are skinny it will be harder for you to lose weight but if your a little chubbier then you would see results quicker
For me it's not about how much you exercise but its about following a healthy eating plan that goes with the exercise and doing it (constantly) that's the . I hope I've answered your question
