hello~ will I be able to lose weight if i walk for 45 minutes 3 times a week? I'm 156cm, 60 - 63kg (my weighing scale cacat, and i weigh myself on the 34th floor O.o). My goal is to be at most 55kg by September. is that possible, just by walking 45 minutes 3 times a week?

Oh ya, without exercise, i am able to maintain my weight at 60-63kg. with the walking I'll be trying to eat the same amount as i did before, instead of more O.o

walk jog intervals thingy so it's possible to lose weight and reach my target?
