Time consuming.... not sure what you are referring to. Do you wish to lose weight quickly? If yes, don't expect this given your current weight. A safe and sustainable weight loss regime with best health outcomes suggest 1/2-1 kg weight loss per week.

Hi there...Weight gain happens either due to addition of extra calories or due to failure to spend calories consumed...these extra calories deposited in our body as fat..for weight reduction you have to consume less calories and spend more...avoid junk foods,carbohydrates like rice etc,avoid oily foods...add proteins and fibre rich foods to your diet with green tea,green leafy vegetables, fruits...do regular exercise at least 2 hours a day...consult nearest dietitian they will do the needful.
