There are many things out there to help you out achieve 60Kg. Of course, you always want it to be the safest way possible. In my case, I dropped 5kg in a few weeks by just cutting down on sugars and Carbohydrates. It is amazing how fast our bodies adjust to changes in diet, the hard part of it is controlling the mental urge of eating. Working out moderately and cutting down in sugars and carbs will get you amazing results in a matter of days. You will be able to notice how good this is!
Best wishes,
